Earlier this month, Ali Mostafavi got an unexpected chance to pilot his company's data-backed and artificial intelligence-powered platform — all while weathering one of Houston's most impactful storms.

Mostafavi, a civil and environmental engineering professor at Texas A&M University, founded Resilitix.AI two years ago, and with the help of his lab at A&M, has created a platform that brings publicly available data into AI algorithms to provide its partners near-real time information in storm settings.

As Hurricane Beryl came ashore with Houston on its path, Mostafavi says he had the opportunity to both test his technology and provide valuable information to his community during the storm.

"We were in the process of fine tuning some of our methods and algorithms behind our technology," Mostafavi says on the Houston Innovators Podcast. "When disasters happen, you go to activation mode. We put our technology development and R&D efforts on hold and try to test our technology in an operational setting."

The platform provides its partners — right now, those include local and state organizations and emergency response teams — information on evacuation reports, street flooding, and even damage sustained based on satellite imagery. Mostafavi says that during Beryl, users were wondering how citizens were faring amid rising temperatures and power outages. The Resilitix team quickly pivoted to apply algorithms to hospital data to see which neighborhoods were experiencing high volumes of patients.

"We had the ability to innovate on the spot," Mostafavi says, adding that his own lack of power and internet was an additional challenge for the company. "When an event happens, we start receiving requests and questions. ... We had to be agile and adapt our methods to be responsive. Then at the same time, because we haven't tested it, we have to verify that we are confident (in the information we provide)."

On the episode, Mostafavi shares how Hurricane Harvey — which occurred shortly after Mostafavi moved to Houston — inspired the foundation of Resilitix and how Houston is the ideal spot to grow the company.

"We are very excited that our company is Houston based," he says. "We should not be just ground zero of disasters. We have to also be ground zero for solutions as well. I believe Houston should be the hub for resilience tech innovation as it is for energy transition.

"I think energy transition, climatetech, energy tech, and disaster tech go hand in hand," Mostafavi continues. "I feel that we are in the right place."

new and improved

Where some might see just a basement, Mayor Sylvester Turner sees an opportunity to tell a story of Houston's resiliency and dedication to sustainability.

When Hurricane Harvey hit Houston, it left 18 to 20 inches of floodwaters in the basement of Houston City Hall. The city received funding from FEMA to support the $4.4 million renovation project that commenced in 2020. After facing challenges — including a defaulted contractor — the city revealed the new space this week, which was completed by contractor Dunhill Construction.

"The City Hall Basement renovation is a testament to the resilient spirit of Houston," says Turner in the news release. "We encountered some challenges, but we've revitalized this space while preserving our history and embracing innovation. This space truly embodies our commitment to a sustainable future."

The new basement holds conference rooms, training facilities, and a wellness center that was donated by Cigna. The project was focused on implementing sustainability and efficiency and included replacing aging air handling units with more efficient technology, LED lighting equipped with sensors to avoid energy waste, and a sliding floodgate to prevent history from repeating itself should another storm hit Houston.

The project also incorporated 18 pieces of Houston-focused art by artists including Mark Chen, Syd Moen, Nancy Newberry, and David Reinfeld. The 49 Houston mayor portraits, which were rescued by a staffer during the storm, were conserved, reframed, and rehung.

The space will also be the home to Houston's first walk-in 311 center, per the release, and the 311’s Continuity of Operations Plan, or COOP, and will be a secondary location in case the main call center fails.

With the completion of the project, the city has a few more upgrades — including additional training facilities, the mayor's dining room, and kitchen — coming soon and set to be completed in November.

City of Houston announces partnership college on 5th anniversary of Hurricane Harvey

preparing the city of Houston

Last week, Houston Mayor Sylvester Turner looked back on the past five years since Hurricane Harvey and made a lofty goal to provide the community with resiliency training.

The city of Houston and Houston Community College signed a memorandum of understanding that will address the city's goal to train 500,000 citizens, employees, small businesses, volunteers, and first responders in new resiliency training programs starting this fall.

The agreement was signed last week at the "Embracing Resiliency Symposium" hosted by the Resilience Innovation Hub, Amegy Bank, and HCC in front of 175 business, civic, community, education, and government leaders attending.

“I am pleased to announce the City of Houston’s partnership with Houston Community College’s new Resilience Center of Excellence and the Operations Training Facility and all the many ways we will collectively pave the path for a stronger and more prepared citizens, workforce, and community and a more resilient future,” Mayor Turner says at the event.

“Five years back, as we faced the wrath and impacts of Hurricane Harvey, it was a moment of reckoning for us as a city. It spurred us to think more cohesively about response and recovery; and most importantly, it urged us to think about building forward from recovery, from response towards resilience," he continues.

Starting this fall, the Houston community will have access to the following seven resiliency courses:

  • Resiliency 101 + Community Emergency Response Training (CERT)
  • Disaster Case Management
  • Facilities and Infrastructure
  • Disaster Recovery
  • Drones, Data Science, and Internet of Things
  • Public Safety and Rescue
  • Medical Triage

An additional 30 courses and programs will follow in 2023.

“As Mayor Turner recently stated, the lessons learned from Hurricane Harvey and subsequent disasters have identified one common take-away: When we work together as a team, Greater Houston is always resilient,” HCC Chancellor Cesar Maldonado says at the event. “In light of this observation, we must remain vigilant so these disasters will not continue to harm our families, our neighborhoods, our companies, our facilities and the community-at-large."

Earlier this summer, HCC announced that it is developing the Resilience Center of Excellence to aid the city’s resilience campaign. At the heart of this project is the 65,000-square-foot, $30 million Resiliency Operations Center, which will be built on a five-acre site HCC’s Northeast campus. The complex is scheduled to open in 2024.

"The HCC Resiliency Center of Excellence and Operations Training Facility will contribute to addressing preparedness and long-term mitigation from future floods, storms, snow and ice, pandemics and other challenges that have cost the region in the loss of lives, community, operations, and economic competitiveness," Maldonado continues.

City of Houston launches pilot program to promote stormwater infrastructure growth

seeing green

The City of Houston has launched a pilot project that will speed up the permitting process for environmentally friendly stormwater projects.

The Green Stormwater Infrastructure Expedited Permitting Pilot Program, announced August 4, will approve at least 10 projects in the Houston area by August 2022. In conjunction with the Resilient Houston initiative, the city is targeting 100 green stormwater infrastructure projects by 2025.

The city is working on rules and regulations that will govern development of green stormwater infrastructure. Mayor Sylvester Turner rolled out a tax abatement program for green stormwater infrastructure projects last December.

According to a city news release, green stormwater infrastructure improves the performance of drainage systems and can make real estate projects more attractive to buyers, while delivering benefits such as heat reduction, improvement of air and water quality, and conservation of native habitats.

Green stormwater infrastructure helps reduce the downstream impact of development and mimics how rain behaves when it falls onto an undeveloped green landscape. Techniques that fit into this category include green roofs, rain gardens, rainwater harvesting, permeable pavement, and urban forests.

"In the aftermath of Hurricane Harvey, we have taken critical steps to address our flooding and drainage challenges. As Houston has rapidly developed, we have relied on traditional gray infrastructure systems to keep us safe. However, as we build forward, we must consider new and innovative approaches for achieving greater flood resilience in Houston," the city says in a 2019 report about green stormwater infrastructure.

Traditional "gray" infrastructure, designed to move urban stormwater away from the built environment, includes curbs, gutters, drains, piping, and collection systems, according to the U.S. Environmental Protection Agency (EPA). Generally, gray infrastructure collects and moves stormwater from impervious surfaces, such as roadways, parking lots, and rooftops, and into a series of pipes that ultimately send untreated stormwater into local waterways.

In tandem with Houston's new permitting program, the city has created the Green Stormwater Infrastructure Awards and Recognition Program. The program salutes green development and redevelopment projects. It "is intended to recognize some of the most effective and exemplary of 'green' building in Houston and encourage more development projects to adopt resilient measures," according to the news release.

Projects considered for the awards program will be judged on factors such as:

  • Proximity to nearby communities.
  • Impact on nearby communities.
  • Efforts to conserve native plants.

Turner says the permitting and awards programs are part of an initiative aimed at "futureproofing our city" to ease harm caused by hurricanes and flooding.

"In Houston and in towns across the U.S., climate change is no longer knocking on our front door; it's broken into the house," Turner wrote in an opinion piece published in July by The Hill.

New Houston hub calls for collaboration for flood and hurricane prevention innovation

Houston innovators podcast episode 43

When it comes to insurance, most people's interaction is pretty limited buying a plan, filing claims when need be, and paying the monthly bill. However, unbeknownst to most of their insured clients, insurance companies are investing in insuratech and new innovations within the natural disaster space.

Richard Seline, managing director of ResilientH20, along with the Insurance Information Institute and The Cannon, to launch the Gulf Coast & Southwest Resilience Innovation Hub to foster this type of technology and bring insuratech startups and the big insurance players to the table — something that's not often done.

"It's two different languages," Seline says on the Houston Innovators Podcast. "There's a whole language and a whole mindset within the insurance industry that is not real well known."

The hub, which is based in downtown Houston's Cannon Tower, has been hard at work hosting virtual pitch events and networking opportunities since it launched in June just as the 2020 hurricane season commenced. Seline explains the mission is threefold: allow for reverse pitching where insurance companies tell innovators what their challenges are in hopes of inspiring new technology, introducing insuratech companies to potential investors or clients, and fostering innovation for new natural disaster prevention innovations.

On the podcast, Seline discusses new endeavors he's working on within his organization and explains the role his feels the new hub has in Houston's innovation ecosystem. To him, the city must work collaboratively to move the needle on growth of its innovation ecosystem.

"The good news is there is a lot of great activity underway in Houston right now — no questions asked," Seline says. "What we are doing can be seen as complimentary and not competitive with anyone else."

From game-changing startups to watch out for to upcoming events and partnerships for the Gulf Coast & Southwest Resilience Innovation Hub, check out the podcast. You can listen to the full interview below — or wherever you stream your podcasts — and subscribe for weekly episodes.

These Houston entrepreneurs and startups are searching for flooding solutions

Flood tech

The feeling is all too familiar for Houstonians. Tropical Storm Imelda hit Houston with devastating flood waters just two years after Hurricane Harvey did its damage.

With any obstacle or challenge, there is room for innovation. Over the past year, InnovationMap has covered various flood tech startups in Houston. Here are six innovations that can make a difference the next time a storm decides to take its toll on Houston.

Self-deploying flood protection for buildings

A self-deploying flood damage prevention device caught Tasha Nielsen's eye on a trip to Denmark, and then launched the U.S. iteration of FloodFrame to bring the technology here.

FloodFrame works by using buoyancy. A lightweight cloth is wrapped around a tube is installed underground outside the perimeter of your home or business. One end of that cloth is attached to a box that is also installed underground. As flooding begins, an automatic system will release the lids to deploy the inflation of the tube that will protect the structure. When the flood comes in, the system will float on top of the flood — kind of like a pool noodle — and protect the structure from the water.

FloodFrame adds a level of security during flooding events and can be considered more cost-effective when compared to the high cost of renovating or rebuilding after flooding.

"Right now we are focused on residential but I think there's a huge potential for it to go commercial. A lot of commercial buildings are self insured, and commercial developers, industrial developers, this would be a drop in the bucket for the overall cost of the entire project," Nielsen tells InnovationMap. "For homeowners, it's kind of a bigger expense, but I think there is the potential for homebuilders to include it as an option in the entire package of a new house because when you put it in to a mortgage, it's only another like $0.50 a month."

Floodwaters from Hurricane Harvey seriously damaged about 600,000 vehicles in the Houston area, which included Rahel Abraham's 2008 Infiniti G35. Now, Abraham's brainchild forms the backbone of her Houston-based startup, ClimaGuard LLC. The company's waterproof, temperature-resistant, portable Temporary Protective Enclosure (TPE) can entirely cover a compact car, sedan, or midsize SUV. It comes in three sizes; the cost ranges from $349 to $499.

To protect a vehicle, someone sets a TPE on the ground, a driveway, or another flat surface, then drives the vehicle onto the bottom part of the product, and connects the bottom and top parts with the zipper. Abraham likens it to a clamshell preserving a pearl.

"My goal is not to make it to where it's an exclusive product — available only to those who can afford it — but I want to be able to help those who it would make even more of an economic impact for," Abraham tells InnovationMap.

A network to find shelter.

It only took a natural disaster for Reda Hicks to make her startup idea into a reality.

"I had been thinking on what it would be like to help people find space to do business in and how businesses find a way to stay in business a long time," Hicks tells InnovationMap. "But, I was afraid of the tech."

Hicks, who has practiced law for almost 15 years, wanted to create a website that allows for people with commercial space — a commercial kitchen, conference room, spare desks, etc. — to list it. Then, space seekers — entrepreneurs, nonprofits, freelancers, etc. — can rent it. When Hurricane Harvey hit, Hicks was kicking herself for not acting on her idea sooner.

"It was really Harvey and having so many people desperate to find space for emergency purposes that made me realize there are so many contexts in which people need space right away for something specific," she says. "Certainly the primary user is the entrepreneur trying to grow their business, but there are so many other reasons why a community would need better access to the space it already has."

Now Hicks is growing GotSpot in hopes that short-term rental space and emergency housing can be smooth sailing no matter the circumstances. Recently, the company was named a finalist for MassChallenge Texas in Austin.

A water-absorbing tower.

In the wake of Hurricane Harvey, many Houstonians began to think of solutions for the next time Mother Nature struck with her full-force of flooding. Gensler designers Chelsea Bryant, Jordan Gomez, Luisa Melendez, Barbara Novoa, Benjamin Nanson, Maria Qi, and Melinda Ubera created a solution as a part of Gensler's By Design program called Fil Trat. The tower can absorb, filter, and store flood waters until the bayou is ready for the water to be released — cleaner than it was before.

During Harvey, thousands of people were displaced, but Fil Trat has a solution for that too. The tower's floors would alternate between filtration floors and shelters, which could house up to 24 families per floor.

While the suggested Houston locale would be by Buffalo Bayou, the group suggests putting the tower in other coastal cities at risk of devastating flooding.

Nearly two years after Hurricane Harvey battered the Houston area, a flock of electronic "rubber ducks" flew above homes in Katy in a broader endeavor to keep first responders and victims connected during natural disasters.

Developers and backers of Project Owl, an Internet of Things (IoT) hardware and software combination, conducted a pilot test of this innovation June 1 — the first day of this year's hurricane season. In the Katy test, 36 "ducks" took flight.

"So, our technology can be deployed to help communities that have been destroyed after natural disasters by providing quickly accessible communications network to coordinate and organize a response," Bryan Knouse, co-founder and CEO of Project Owl, tells InnovationMap.

The DuckLink network comprises hubs resembling rubber ducks, which can float in flooded areas if needed. It takes only five of these hubs to cover one square mile. This network sends speech-based communications using conversational systems (like Alexa and Facebook Messenger) to a central application. The app, the Owl software incident management system, relies on predictive analytics and various data sources to build a dashboard for first responders.

Restored native wetland coastal prairies.

Before it was the fourth largest city in America, Houston was a prairie. That type of ecosystem — thick with prairie grass — is very absorbing when it comes to rain water. Cassidy Brown Johnson, a Rice University lecturer and president of the Coastal Prairie Partnership, has been taking every opportunity to raise awareness on the importance of prairie restoration.

"It's really surprising to people that the trees and all this lushness is actually all artificial," Johnson says. "We know that this ecosystem evolved with the cyclical flooding events that happened here."

This movement to bring back Houston's ancient ecosystem is a new focus on a few prairie conservationist groups — and even the Harris County Flood Control. This has been going on for a while, but recent flooding events have opened the eyes of people now looking for reliable solutions to flooding problems.

"After Hurricane Harvey, people started realizing that this might be one of the solutions we could actually investigate and see if it can help us," Johnson says. "A green space is going to absorb way more water than a parking lot."

Memorial Park Conservancy's master plan redevelopment project, which is being supported by the Kinder Foundation, includes a lot of prairie restoration plans is expected to deliver by 2028.

The project is a collaborative effort between MPC, Uptown Houston TIRZ, and Houston Parks, Kinder Foundation, and Recreation Department to redevelop the 1,500-acre park. An ongoing part of the transformation will be stormwater management upgrades. MPC has budgeted $3 million to this asset of the renovation. While a part of the plan is tributaries for run-off water, bringing back prairie and wetlands will do a great deal to help abate stormwater.

"We're taking ball fields, parking lots, and roads and converting them back to what was here — native wetland coastal prairie," MPC president and CEO Shellye Arnold tells InnovationMap. "This serves important stormwater purposes."

Houston scientist wins prestigious Pew Scholar award for brain cancer research

standout scholar

Christina Tringides, an assistant professor of materials science and nanoengineering at Rice University, is one of 21 scientists to win a prestigious Pew Biomedical Scholar award.

She is the first faculty member from Rice to win the distinction, which provides $300,000 over four years for advances in biomedicine, according to the university. The awards are granted to researchers who are in the first few years at the assistant professor level.

In Tringides’ case, the funding will support her innovative new method of modeling glioblastoma, a common and extremely aggressive form of brain cancer. Thanks to producing its own blood supply, glioblastoma spreads quickly, weaving tendrils of blighted tissue throughout the brain. Because of this, surgery is difficult and conventional therapies ineffective.

Understanding the way glioblastoma spreads is crucial to the search for a cure. Tringides is using hydrogels that mimic the brain’s extracellular matrix. Using cultures and a microscopic labyrinth, her team can see how the cancer spreads, bonds with neurons and changes cell wall activity. Essentially, Tringides has devised an intelligence test for tumors in hopes of learning how to outsmart them.

“As cancer crawls through the maze, we can look at how it is interacting with the neurons more and more, and measure how electrical activity is changing as a result,” she said in a news release from Rice.

Examining how cancer cells grow can reveal which conditional changes slow them down. Finding ways to alter the structure of brain matter in a way that makes it inhospitable to the cancer could lead to therapies that would impede growth or even reverse it. Using her custom-made ersatz brain maze makes it easier to observe changes than it would be in a patient’s brain.

“Imaging synapses is time-intensive ⎯ it can involve large data files that are hard to visualize, but if we know that the only place where we might have a synapse is this tiny 1-by-4-by-10 micron channel, it makes it much faster and reliable to image them,” Tringides said.

Born in Ames, Iowa, Tringides received her doctorate in biophysics from Harvard before joining Rice in 2024 through a Cancer Prevention and Research Institute of Texas (CPRIT) recruitment award.

Her research was also one of the first four projects to receive research awards through the Rice Brain Institute and TMC Neuro Collaboration Seed Grant Program.

Texas residents earn 11th highest income in U.S., says 2026 study

Money Matters

A new WalletHub study comparing income disparities across America has ranked Texas residents No. 11 on the list of states with the highest earning residents in the nation.

The report, "States Where People Have the Highest Income (2026)," analyzed U.S. Census Bureau income data in all 50 states and the District of Columbia. The report evaluated the average annual income of the top five percent, the median annual household income, and the average annual income of the bottom 20 percent of residents in every state, all adjusted for the cost of living.

The report's data revealed the top five percent of Texans, the highest earners, make $520,378 on average yearly after adjusting for the cost of living. That's the seventh-highest income among the top five percent of earners nationwide.

Meanwhile, the median annual income of a Texas household is just under $76,000. The bottom 20 percent of Texas residents make $17,651 a year, the report found.

For additional context, the latest data from the Federal Reserve shows an American household's median yearly income is about $83,700. WalletHub analyst Chip Lupo also found that the highest earning 10 percent of individuals in the U.S. earn over 12 times more than those in the lowest-earning 10 percent, based on the latest Census data.

"By measuring the income of various percentiles against a state's median income, we can better identify where income disparities are more prevalent, which could help us better understand why residents of certain states struggle more to make ends meet," said Lupo.

Virginia is the state where residents earn the highest income in the U.S., WalletHub said. Based on the report's findings, the top five percent of Virginians make $545,097 on average per year after adjusting for the cost of living. The median annual income of a Virginia household comes out to $95,339, and the bottom 20 percent of residents make $19,671 annually on average.

Conversely, West Virginia is the state where people have the lowest income in the U.S. A West Virginia household makes a median annual income of $56,610, the third-lowest nationally, and the bottom 20 percent of residents make $13,260 on average per year, which is the fifth-lowest in the nation. The top five percent of West Virginians make $372,218 on average per year.

The top 10 states where residents have the highest income are:

  • No. 1 – Virginia
  • No. 2 – New York
  • No. 3 – New Jersey
  • No. 4 – Washington
  • No. 5 – Connecticut
  • No. 6 – Utah
  • No. 7 – Colorado
  • No. 8 – Minnesota
  • No. 9 – Illinois
  • No. 10 – Massachusetts

23 Houston companies rank among America’s most future-ready businesses

future focused

By one measure, Spring-based tech giant Hewlett Packard Enterprises reigns as the most future-ready Houston-area company on the S&P 500 stock index.

HPE sits at No. 72 in a first-time ranking of the best S&P 500 companies for the future. Including HPE, 23 Houston-area companies appear on the list.

Published by The Wall Street Journal, the ranking was created by Bendable Labs for the WSJ Leadership Institute. It evaluates how S&P 500 companies stack up in six areas: AI readiness, innovation, talent readiness, financial fitness, resilience and agility. To be ranked, a company had to be part of the S&P 500 as of Dec. 31.

Among the six categories, HPE ranked highest for innovation (No. 30) among local companies. The WSJ didn’t say why HPE scored so well for innovation. However, the company stands out in this category thanks to:

  • Creation of the El Capitan and Frontier supercomputing systems
  • Research into photonic computing and quantum networking
  • Last year’s $14 billion acquisition of Juniper Networks, giving HPE an edge in AI-native networking
  • Establishment of the everything-as-a-service GreenLake hybrid cloud platform for data centers, colocation facilities and edge computing environments

In an interview with the Six Five podcast at HPE Discover 2025 in Las Vegas, CEO Antonio Neri said the company’s strategy is “basically founded on innovation, and that innovation drives shareholder value over the long term.”

While HPE fared well in the innovation category, it ranked toward the bottom for financial fitness. What’s behind the No. 430 ranking in the financial category? HPE’s low score likely reflects a debt-heavy acquisition strategy coupled with a historically low-margin hardware business.

Here’s the full list of the 23 Houston-area companies included in the ranking of the best companies for the future:

  • No. 72 Hewlett Packard Enterprise
  • No. 105 SLB
  • No. 120 Baker Hughes
  • No. 125 ConocoPhillips
  • No. 158 NRG Energy
  • No. 176 Targa Resources
  • No. 185 Chevron
  • No. 195 Halliburton
  • No. 223 Coterra Energy
