A Houston biotech startup is one step closer to releasing its marquee drug for the global insulin market, which is projected to break the $90 billion threshold by 2029.

rBIO says it recently completed testing of the properties of R-biolin, an insulin drug that’s biologically identical to Novo Nordisk’s Novolin drug. The patent for Novolin about two decades ago. In March 2023, the Dutch drugmaker announced it was slashing the list price of Novolin by 65 percent to $48.20 per vial and $91.09 per FlexPen.

Executives at rBIO are now pursuing a partnership with a contract research organization to manage clinical trials of R-biolin. If those trials go well, R-biolin will seek approval to supply its insulin therapy to diabetes patients around the world.

Washington University in St. Louis is rBIO’s academic partner for the R-biolin project.

The rBIO platform produces insulin at greater yields that traditional manufacturing techniques do. The company is striving to drive down the cost of insulin by 30 percent.

About 38 million Americans have diabetes, with the vast majority being treated for type 2 diabetes, according to the U.S. Centers for Disease Control and Prevention (CDC). Many people with diabetes must take insulin to control their blood sugar levels.

Research company iHealthcareAnalyst predicts the global market for insulin will surpass the $90 billion mark in 2029.

“There has been a lot of talk in the media about reducing the cost of insulin for diabetic patients, but what is often overlooked is that the domestic demand for insulin will soon outpace the supply, leading to a new host of issues,” Cameron Owen, co-founder and CEO of rBIO, says in a news release.

“We’re dedicated to addressing the growing demand for accessible insulin therapies, and … we’re thrilled to announce the viability of our highly scalable manufacturing process.”

Professionals from the University of California San Diego and Johns Hopkins University established rBIO in 2020. The startup moved its headquarters from San Diego to Houston in 2022.

Houston doesn't have too many unicorns — startups valued at $1 billion or more — in its innovation ecosystem, but Solugen, a sustainable chemicals company, is among the elite group. Gaurab Chakrabarti, the CEO and co-founder of the company, joined Houston House by the Greater Houston Partnership, to share his story on the SXSW stage.

“You do make your own luck, but you have to be putting in the work to do it," Chakrabarti says, adding that it's not an easy thing to accomplish. “There are things you can be doing to increase your luck surface area."

He shared several lessons he learned on his founder journey in the discussion. Read more.

Following the failure of Silicon Valley Bank, there's one thing Sandy Guitar can say has changed for Houston innovators: Bank diversification is going to be a must.

“We didn't think we needed one last week, but this week we know we need a resilience plan," she says, explaining that bank diversification is going to be added to "the operational due diligence playbook." Read more.

Founded in San Diego, rBIO recently relocated to Houston and has big plans for settling in the city, says Cameron Owen, the company's co-founder and CEO.

“Companies from California like us and the coastal areas were converging here in Houston and creating this new type of bioeconomy,” he tells InnovationMap.

He shares that Houston wasn't originally on his radar, until it was. A visit turned into a relocation, and it's just the beginning for the biotech startup that's focused on using synthetic biology for pharmaceuticals. Read more.

California-founded biotech startup relocates to join Houston's emerging bioeconomy

new to hou

Cameron Owen had an idea for a synthetic biology application, and he pitched it to a handful of postdoctoral programs. When he received the feedback that he didn't have enough research experience, he decided to launch a startup based in San Diego around his idea. He figured that he'd either get the experience he needed to re-apply, or he'd create a viable company.

After three years of research and development, Owen's path seems to have taken him down the latter of those two options, and he moved his viable company, rBIO, to Houston — a twist he didn't see coming.

“Houston was not on my radar until about a year and a half ago,” Owen says, explaining that he thought of Houston as a leading health care hub, but the coasts still had an edge when it came to what he was doing. “San Diego and the Boston area are the two big biotech and life science hubs.”

But when he visited the Bayou City in December of 2021, he says he saw first hand that something new was happening.

“Companies from California like us and the coastal areas were converging here in Houston and creating this new type of bioeconomy,” he tells InnovationMap.

Owen moved to Houston last year, but rBIO still has an academic partner in Washington University in St. Louis and a clinical research organization it's working with too, so he admits rBIO's local footprint is relatively small — but not for long.

"When we look to want to get into manufacturing, we definitely want to build something here in Houston," he says. "We’re just not to that point as a company."

In terms of the stage rBIO is in now, Owen says the company is coming out of R&D and into clinical studies. He says rBIO has plans to fundraise and is meeting with potential partners that will help his company scale and build out a facility.

With the help of its CRO partner, rBIO has two ongoing clinical projects — with a third coming next month. Owen says right now rBIO is targeting the pharmaceutical industry’s biologics sector — these are drugs our bodies make naturally, like insulin. About 12 percent of the population in the United States has diabetes, which translates to almost 40 million people. The demand for insulin is high, and rBIO has a way to create it — and at 30 percent less cost.

This is just the tip of the iceberg — the world of synthetic biology application is endless.

“Now that we can design and manipulate biology in ways we’ve never been able to before,” Owen says, "we’re really only limited by our own imagination.”

Synthetic biology is a field of science that involves programing biology to create and redesign natural elements. While it sounds like science fiction, Owen compares it to any other type of technology.

“Biology really is a type of software,” he says. “Phones and computers at their core run on 1s and 0s. In biology, it’s kind of the same thing, but instead of two letters, it’s four — A, C, T, and G.”

“The cool thing about biology is the software builds the hardware,” he continues. “You put that code in there and the biology builds in and of itself.”

Owen says the industry of synthetic biology has been rising in popularity for years, but the technology has only recently caught up.

“We’re exploring a brave new world — there’s no doubt about that,” Owen says.

Houston residents rank economy as biggest problem, new Kinder survey shows

by the numbers

The region’s economy tops the list of concerns of Houston-area residents surveyed by Rice University’s Kinder Institute for Urban Research.

Respondents in the Kinder Houston Area Survey, which questioned nearly 9,000 residents of Harris, Fort Bend and Montgomery counties, cite the regional economy as the area’s “biggest problem.”

Shrinking confidence in job opportunities and growing household financial pressures fueled the grim economic outlook:

  • The share of residents rating job prospects as “good” or “excellent” fell by more than 25 percentage points, the sharpest single-year decline since the 1980s.
  • Seventy-nine percent of those earning less than $25,000 said they’d be unable to cover an unplanned $400 expense. That was up from 72 percent last year. In the $50,000-to-$99,999 category, the figure was 39 percent, up from 30 percent last year.
  • More than 20 percent of residents said their financial status was worse than it was 12 months earlier.

“These challenges were particularly notable among lower- and middle-earning households,” according to a report about the survey.

Dan Potter, co-director of the institute’s Houston Population Research Center, says the annual survey “provides community leaders and the public with a map of where we’ve been on key issues, where we are now, and what’s of looming importance. It allows everyone to work together toward a better future for our city and our region.”

Houston-based Oxy officially announces CEO transition, names successor

Team Transition

Houston-based Occidental (Oxy) has officially announced its longtime CEO's retirement and her successor.

Oxy shared that Vicki Hollub will retire June 1. Reuters first reported Hollub's plan to retire in March, but a firm date had not been set. Hollub will remain on Oxy's board of directors.

Richard Jackson, who currently serves as Oxy's COO, will replace Hollub in the CEO role.

“It has been a privilege to lead Occidental and work alongside such a talented team for more than 40 years," Hollub shared in a news release. "Following the recently completed decade-long transformation of the company, we now have the best portfolio and the best technical expertise in Occidental’s history. With this strong foundation in place, a clear path forward and a leader like Richard, who has the experience and vision to elevate Occidental, now is the right time for this transition. “I look forward to supporting Richard and the Board through my continued role as a director.”

Hollub has held the top leadership position at Oxy since 2016 and has been with the energy giant for more than 40 years. Before being named CEO, she served as COO and senior executive vice president at the company. She led strategic acquisitions of Anadarko Petroleum in 2019 and CrownRock in 2024, and was the first woman selected to lead a major U.S. oil and gas company.

Hollub also played a key role in leading Oxy's future as a "carbon management company."

Jackson has been with Oxy since 2003. He has held numerous leadership positions, including president of U.S. onshore oil and gas, president of low carbon integrated technologies, general manager of the Permian Delaware Basin and enhanced oil recovery oil and gas, vice president of investor relations, and vice president of drilling Americas.

He was instrumental in launching Oxy Low Carbon Ventures, which focuses DAC, carbon sequestration and low-carbon fuels through businesses like 1PointFive, TerraLithium and others, according to the company. He also serves on the Oil and Gas Climate Initiative’s Climate Investment Board and the American Petroleum Institute’s Upstream Committee. He holds a bachelor's degree in petroleum engineering from Texas A&M University.

Jackson was named COO of Oxy in October 2025. In his new role as CEO, he will also join the board of directors, effective June 1.

“I am grateful to be appointed President and CEO of Occidental and excited about the opportunity to execute from the strong position and capabilities that we built under Vicki’s leadership,” Jackson added in the release. “It means a lot to me personally to be a part of our Occidental team. I am committed to delivering value from our significant and high-quality resource base. We have a tremendous opportunity to focus on organic improvement and execution to deliver meaningful value for our employees, shareholders and partners.”

Rice Brain Institute awards seed grants for dementia, Alzheimer’s research

brain trust

The recently established Rice Brain Institute awarded 12 seed grants last month to support research on dementia, Alzheimer’s disease, Parkinson’s disease and other neurological disorders.

The grants are part of the Rice DPRIT Seed Grant Program, which aims to help faculty members generate preliminary data, test and teams that would be supported under the Dementia Prevention and Research Institute of Texas.

The DPRIT was approved last year to provide $3 billion in state funding over a 10-year span for research on dementia prevention and other neurological conditions. It will be modeled after the Cancer Prevention and Research Institute of Texas (CPRIT), which has awarded nearly $4 billion in grants since 2008.

“DPRIT is a historic initiative with transformative impact potential and at Rice we are very well equipped to contribute to its mission and help make Texas a leader in brain health and innovation,” Behnaam Aazhang, a Rice professor of electrical and computer engineering and director of the Neuroengineering Initiative and the RBI, said in a news release.

The Rice DPRIT Seed Grant Program is supported by the RBI and the Educational and Research Initiative for Collaborative Health (ENRICH) office at Rice. Most of the funding came from Rice's Office of Research, with a contribution from Rice's Amyloid Mechanism and Disease Center, which also launched last year.

A number of the teams include collaborators from Houston's Texas Medical Center, including Baylor College of Medicine, University of Texas Medical Branch and the McGovern Medical School at UTHealth Houston.

The 12 teams are:

  • Keya Ghonasgi, assistant professor of mechanical engineering at Rice. Ghonasgi's research addresses the high risk of falls among people with different types of dementia and aims to develop a personalized, home-based fall-prevention approach using textile-integrated wearable sensors.
  • Luz Garcini, associate professor of psychological sciences at Rice, and Hannah Ballard, associate director of community and public health at the Kinder Institute for Urban Research at Rice. Garcini and Ballard's research looks at barriers and facilitators to early detection of Alzheimer’s disease in diverse, medically underserved urban communities and focuses on populations that experience late diagnosis, including Hispanic/Latino groups.
  • Lei Li, assistant professor of electrical and computer engineering at Rice, and Pablo Valdes, assistant professor of neurosurgery at UTMB. Li and Valdes' project develops a noninvasive, bedside imaging approach to monitor brain blood flow and oxygenation in patients recovering from stroke or brain surgery using photoacoustic imaging through a specialized transparent skull implant.
  • Cameron Glasscock, assistant professor of biosciences at Rice. Glasscock's project addresses repeat expansion disorders, such as Huntington’s disease and myotonic dystrophy, and focuses on stopping DNA instability before repeats reach a disease-causing threshold.
  • Raudel Avila, assistant professor of mechanical engineering at Rice. Avila's project focuses on everyday health factors such as nutrition, hydration and brain blood flow and how they influence brain aging long before symptoms of dementia appear.
  • Isaac Hilton, associate professor of bioengineering at Rice, and Laura Lavery, assistant professor of biosciences at Rice. Hilton and Lavery's project uses precise CRISPR-based gene regulation to target multiple genetic drivers of neuronal damage in Alzheimer’s.
  • Quanbing Mou, assistant professor of chemistry at Rice, and Qing-Long Miao, assistant professor of neurology at Baylor College of Medicine. Mou and Miao's project aims to develop a gene-regulation therapy for childhood absence epilepsy by restoring activity of the CACNA1A gene.
  • Momona Yamagami, assistant professor of electrical and computer engineering at Rice, and Christopher Fagundes, professor of psychological sciences at Rice. Yamagami and Fagundes' project addresses the physical and mental health challenges faced by spouses caring for partners with Alzheimer’s disease and related dementias and aims to develop algorithms to determine the optimal timing and frequency of supportive text messages.
  • Han Xiao, professor of chemistry at Rice. Xiao's project aims to improve the delivery of antibody therapies to the brain using a noninvasive, light-based approach that temporarily opens the blood–brain barrier.
  • Lan Luan, associate professor of electrical and computer engineering at Rice. Luan's project investigates how tiny blood-vessel injuries in the brain, known as microinfarcts, contribute to dementia.
  • Natasha Kirienko, associate professor of biosciences at Rice. Kirienko's project targets a shared cause of neurodegeneration, impaired mitochondrial cleanup, and aims to identify an existing antidepressant that could be repurposed to protect neurons in diseases like Alzheimer’s and Parkinson’s.
  • Harini Iyer, assistant professor of biosciences at Rice. Iyer's project will observe zebrafish to investigate how the brain’s primary immune cells become improperly activated in neurological disorders, leading to the loss of healthy neurons and cognitive impairment.

The RBI also named the first four projects to receive research awards through the Rice and TMC Neuro Collaboration Seed Grant Program in January. Read more about those projects here.
