Houston and Boston climate tech incubator Greentown Labs has named Georgina Campbell Flatter as the organization’s incoming CEO.

Flatter will transition to Greentown from her role as co-founder and executive director of TomorrowNow.org, a global nonprofit that studies and connects next-generation weather and climate technologies with communities most affected by climate change.

“We are at a transformational moment in the energy transition, with an unprecedented opportunity to drive solutions in energy production, sustainability, and climate resilience,” Flatter said in a news release. “Greentown Labs is, and has always been, a home for entrepreneurs and a powerhouse of collaboration and innovation.”

Previously, Flatter worked to launch TomorrowNow out of tomorrow.io, a Boston-based AI-powered weather intelligence and satellite technology company. The organization secured millions in climate philanthropy from partners, including the Gates Foundation, which helped deliver cutting-edge climate solutions to millions of African farmers weekly.

Flatter also spent 10 years at the Massachusetts Institute of Technology (MIT), where she was a senior lecturer and led global initiatives at the intersection of technology and social impact. Her research work includes time at Langer Lab and Sun Catalytix, an MIT – ARPA-E-funded spin-out that focused on energy storage solutions inspired by natural photosynthesis. Flatter is also an Acumen Rockefeller Global Food Systems Fellow and was closely involved with Greentown Labs when it was founded in Boston in 2011, according to the release.

“It’s rare to find an individual who has impressive climate and energy expertise along with nonprofit and entrepreneurial leadership—we’re fortunate Georgie brings all of this and more to Greentown Labs,” Bobby Tudor, Greentown Labs Board Chair and Chairman of the Houston Energy Transition Initiative, said in a news release.

Flatter will collaborate with Kevin Dutt, Greentown’s Interim CEO, and also continue to serve on Greentown’s Board of Directors, which was recently announced in December and contributed to a successful $4 million funding round. She’s also slated to speak at CERAWeek next month.

“In this next chapter, I’m excited to build on our entrepreneurial roots and the strength of our ever-growing communities in Boston and Houston,” Flatter added in a news release. “Together, we will unite entrepreneurs, partners, and resources to tackle frontier challenges and scale breakthrough technologies.”

Greentown also named Naheed Malik its new chief financial officer last month. The announcements come after Greentown’s former CEO and president, Kevin Knobloch, announced that he would step down in July 2024 after less than a year in the role.

Future-focused Houston nonprofit names new leader

taking the helm

A nonprofit organization dedicated to leading Houston into the future has named its next leader.

The Center for Houston’s Future named David Gow as president and CEO, succeeding Brett Perlman, who was announced in April to be remaining at the Center with a focus on the Center’s hydrogen initiative. Gow is the founder and chairman of Gow Media, InnovationMap's parent company. His role is effective September 3.

“I am excited to step into this opportunity with the Center and work with the team, the board and many other stakeholders to help shape Houston’s future,” Gow says in a news release. “The Center presents an exciting opportunity to cast a vision for our region and identify initiatives that will make an impact.”

Gow — whose career includes a portfolio of online media properties and ESPN Radio — is a board member of Goose Capital and chair of MSAI, an entity he formed through a SPAC acquisition. Before he founded Gow Media, he served as CFO and CEO of an online watch retailer, Ashford.com. Prior to Ashford, Gow was director of corporate strategy at Compaq Computers and a consultant at McKinsey & Co. He received his master’s in public policy from Harvard and his bachelor's in economics from Williams College.

“David’s portfolio of experiences and skills, record of innovation and success, and deep commitment to the Houston community make him the perfect fit to lead the Center as we chart and execute on our next set of initiatives focused on ensuring a bright future for all residents in the Houston region,” adds Center for Houston’s Future Board Chair Cindy Yeilding.

In his new role, Gow will lead the Center’s next effort, Vision 2050, which plans to identify the city's key issues, gaps, and opportunities.

“Today’s announcement also reflects the success of the Center’s clean hydrogen program,” Yeilding continues. “On behalf of the Center’s board, I’d also like to recognize Brett for launching and building such a successful and important effort as well as his overall leadership and record of achievement at the Center these past seven years.”

Houston med device company names new CEO

new hire

Houston-based medical device company BiVACOR has brought aboard a new CEO.

Jim Dillon, a longtime executive in the medical device sector, has been hired to lead BiVACOR and join its board of directors. Dillon succeeds former heart surgeon Dr. Thomas Vassiliades, whose appointment as CEO was announced in January 2022.

“Jim’s leadership style, combined with his experience in building high-performance teams as well as expertise in the heart failure field, makes him the ideal person to lead BiVACOR,” Raymond Cohen, chairman of BiVACOR, says in a news release.

Cohen was named chairman of BiVACOR in December 2023.

Most recently, Dillon was CEO of Massachusetts-based BioVentrix, a medical device company that focuses on minimally invasive procedures aimed at preventing heart failure. He previously held sales and marketing positions at medical device companies Abiomed, TherOx, and InfraReDx.

In November, the U.S. Food and Drug Administration (USDA) paved the way for BiVACOR to conduct a first-in-human clinical feasibility study of its Total Artificial Heart product. The study, initially featuring three patients at Houston’s Texas Heart Institute, is set to start during the first half of 2024. It will evaluate the device’s use as a substitute for a heart transplant.

The device “is unique in its complexity and importance as an advanced treatment option for end-stage biventricular heart failure patients,” Dillon says, and promises “to truly revolutionize the field.”

About 100,000 patients suffering from severe heart failure could benefit from BiVACOR’s artificial heart, the company says. For these patients, drug therapy is limited and the health prognosis is bleak, given the scarcity of donor hearts around the world.

Founded in 2008, BiVACOR maintains its headquarters in Houston, along with offices in Huntington Beach, California, and Brisbane, Australia.

To date, BiVACOR has raised nearly $37.8 million, according to CB Insights. The company’s investors include Boston-based Cormorant Asset Management, Australia-based OneVentures, the Australia Department of Health, and the National Institutes of Health (NIH).

Houston medical device startup names new CEO

now at the helm

Houston-based medical device company Saranas has tapped a veteran of the healthcare industry as its new CEO.

Mike MacKinnon most recently was president and partner at Madison Ventures +, a private equity firm based in Greenwood Village, Colorado. The firm invests in companies in healthcare, real estate, finance, and other sectors.

Before joining Madison Ventures +, MacKinnon was CEO of Zidan Medical, a startup focused on treatment of airway lesions in patients with early stage lung cancer. He served in that role from 2019 to 2023.

Earlier, he was CEO of ROX Medical, a medical device company specializing in minimally invasive vascular therapy for patients with uncontrolled high blood pressure. He held that role from 2018 to 2019. He previously worked at Philips North America, Volcano, AtheroMed, Hansen Medical, Access Closure, and FoxHollow Technologies.

In a news release, Dan Wolterman, chairman of Saranas’ board and former president and CEO of Memorial Hermann Health System, calls MacKinnon “an accomplished executive with an impressive record of bringing disruptive technology to market, guiding strategy, and driving significant growth.”

Now president and CEO of Nashua, New Hampshire-based medical device company Conformal Medical, James Reinstein was president and CEO of Saranas from 2020 to 2022. Prior to Reinstein, Zaffer Syed held that position from 2017 to 2020. He's still an adviser for the company and recently announced his role as entrepreneur in residence at the Texas Medical Center.

Saranas is working on commercializing its Early Bird Bleed Monitoring System, touted as the first and only system FDA-approved bleeding detection system for procedures involving blood vessels. It is designed to detect bleeds early, enabling physicians to reduce medical risks and potentially avoid costly medical problems.

“Bleeding remains a common issue during and after endovascular procedures and can result in life-threatening complications,” says MacKinnon.

Since being founded in 2013, Saranas has treated over 1,200 patients with its device and has received $29.2 million in funding, according to Crunchbase. This includes a $12.8 million Series B round that Saranas got in 2021 from Chicago-based Baird Capital and Austin-based S3 Ventures.

The Early Bird device was developed at Houston’s Texas Heart Institute. The FDA approved the device in 2019.

Houston leaders form coalition to boost Texas power grid with new tech

a better grid

A Houston-based coalition that launched this month aims to educate Texas officials about technology designed to shore up the state’s power grid.

The public-private Texas Reliability Coalition says it will promote utility-scale microgrid technology geared toward strengthening the resilience and reliability of the Texas power grid, particularly during extreme weather.

A utility-operated microgrid is a group of interconnected power loads and distributed energy sources that can operate in tandem with or apart from regular power grids, such as the grid run by the Electric Reliability Council of Texas (ERCOT). Legislation passed in 2023 enables the use of utility-scale microgrid technology in Texas’ deregulated energy market, according to the coalition.

John Elder, executive director of the coalition, says that with the legal framework now in place, the Public Utility Commission of Texas and ERCOT need to create rules to establish the Texas marketplace for microgrid technology. The goal, he says, is to “take the Texas grid from good to great” by installing microgrid technology, improving the infrastructure, and strengthening the system — all targeted toward meeting power needs during extreme weather and amid growing demand.

Houston-based CenterPoint Energy will test the utility-scale microgrid technology being promoted by the coalition. In a January 31 filing with the Public Utility Commission, CenterPoint says microgrid technology will be featured in a $36.5 million pilot program that’ll set up an estimated three to five microgrids in the company’s service area. The pilot program is slated to last from 2026 to 2028.

In the public affairs arena, five Houston executives are leading the new reliability commission’s microgrid initiative.

Elder, one of the coalition’s founding members, is president and CEO of Houston-based Acclaim Energy. Other founders include Ember Real Estate Investment & Development, Park Eight Development, and PowerSecure. Ember and Park Eight are based in Houston. Durham, North Carolina-based PowerSecure, which produces microgrid technology, is a subsidiary of energy provider Southern Co.

Aside from Elder, members of the coalition’s board are:

  • Stewart Black, board secretary of the coalition and vice president of Acclaim Energy’s midstream division
  • Todd Burrer, president of municipal utility districts at Inframark
  • Harry Masterson, managing principal of Ember
  • Martin Narendorf, former vice president at CenterPoint Energy

This Houston neighbor is the fastest growing wealthy suburb in America

By The Numbers

The Houston-area city of Fulshear is booming like nowhere else: It's now the No. 1 fast-growing affluent suburb in the country.

Fulshear's No. 1 status was unveiled in a new GoBankingRates' study that ranked the "30 Fastest Growing Wealthy Suburbs in America" for 2025. The report examined population changes from 2018 to 2023 among cities and towns in major U.S. metro areas with populations between 25,000 and 100,000 residents. Median household income, average home value, and a "livability score" were also calculated for each locale.

Fulshear, located 34 miles west of downtown Houston, experienced the most dramatic population increase out of all 30 cities in the report. Though the suburb only has an estimated population of 42,616 residents, that number has skyrocketed 237 percent during the five-year period.

A Fulshear resident's median income is $178,398 annually, and the average value of a home in the city comes out to $521,157, the report additionally found.

Fulshear was the second fastest growing city in America in 2023. The city's growth is further reflected by the number of new apartments that were built in the area in 2024.

Texas is tops
Texas cities took the top three fastest growing U.S. suburbs for 2025, with Dallas-area cities of Celina (No. 2) and Prosper (No. 3) experiencing wildly different (yet still sky high) population changes. Celina's population ballooned 190 percent to 43,317 residents, while Prosper's grew 81 percent to an estimated 41,660 people.

Other Texas cities that earned spots in the report include Flower Mound (No. 19), Southlake (No. 27), University Park (No. 28) and Colleyville (No. 29), all in the Dallas-Fort Worth area.

"The old adage that everything is bigger in Texas is true, considering the number of Lone Star State suburbs that are quickly growing in population and overall wealth," the report's author wrote.

The top 10 fastest growing wealthy suburbs in America are:

  • No. 1 – Fulshear, Texas
  • No. 2 – Celina, Texas
  • No. 3 – Prosper, Texas
  • No. 4 – Erie, Colorado
  • No. 5 – Clarksburg, Maryland
  • No. 6 – Zionsville, Indiana
  • No. 7 – Redmond, Washington
  • No. 8 – Dublin, California
  • No. 9 – Parkland, Florida
  • No. 10 – Eastvale, California

Rice research breakthrough paves the way for advanced disease therapies

study up

Bioengineers at Rice University have developed a “new construction kit” for building custom sense-and-respond circuits in human cells, representing a major breakthrough in the field of synthetic biology, which could "revolutionize" autoimmune disease and cancer therapeutics.

In a study published in the journal Science, the team focused on phosphorylation, a cellular process in the body in which a phosphate group is added to a protein, signaling a response. In multicellular organisms, phosphorylation-based signaling can involve a multistage, or a cascading-like effect. Rice’s team set out to show that each cycle in a cascade can be treated as an elementary unit, meaning that they can be reassembled in new configurations to form entirely novel pathways linking cellular inputs and outputs.

Previous research on using phosphorylation-based signaling for therapeutic purposes has focused on re-engineering pathways.

“This opens up the signaling circuit design space dramatically,” Caleb Bashor, assistant professor of bioengineering and biosciences and corresponding author on the study, said in a news release. “It turns out, phosphorylation cycles are not just interconnected but interconnectable … Our design strategy enabled us to engineer synthetic phosphorylation circuits that are not only highly tunable but that can also function in parallel with cells’ own processes without impacting their viability or growth rate.”

Bashor is the deputy director for the Rice Synthetic Biology Institute, which launched last year.

The Rice lab's sense-and-respond cellular circuit design is also innovative because phosphorylation occurs rapidly. Thus, the new circuits could potentially be programmed to respond to physiological events in minutes, compared to other methods, which take hours to activate.

Rice’s team successfully tested the circuits for sensitivity and their ability to respond to external signals, such as inflammatory issues. The researchers then used the framework to engineer a cellular circuit that can detect certain factors, control autoimmune flare-ups and reduce immunotherapy-associated toxicity.

“This work brings us a whole lot closer to being able to build ‘smart cells’ that can detect signs of disease and immediately release customizable treatments in response,” Xiaoyu Yang, a graduate student in the Systems, Synthetic and Physical Biology Ph.D. program at Rice who is the lead author on the study, said in a news release.

Ajo-Franklin, a professor of biosciences, bioengineering, chemical and biomolecular engineering and a Cancer Prevention and Research Institute of Texas Scholar, added “the Bashor lab’s work vaults us forward to a new frontier — controlling mammalian cells’ immediate response to change.”
