Houston hardtech accelerator names 8 scientists to 2025 cohort

ready, set, activate

National hardtech-focused organization Activate has named its 2025 cohort of scientists, which includes new members to Activate Houston.

The Houston hub was introduced last year, and joins others in Boston, New York, and Berkley, California—where Activate is headquartered. The organization also offers a virtual and remote cohort, known as Activate Anywhere. Collectively, the 2025 Activate Fellowship consists of 47 scientists and engineers from nine U.S. states.

This year's cohort comprises subject matter experts across various fields, including quantum, robotics, biology, agriculture, energy and direct air capture.

Activate aims to support scientists at "the outset of their entrepreneurial journey." It partners with U.S.-based funders and research institutions to support its fellows in developing high-impact technology. The fellows receive a living stipend, connections from Activate's robust network of mentors and access to a curriculum specific to the program for two years.

“Science entrepreneurship is the origin story of tomorrow’s industries,” Cyrus Wadia, CEO of Activate, said in an announcement. “The U.S. has long been a world center for science leadership and technological advancement. When it comes to solving the world’s biggest challenges, hard-tech innovation is how we unlock the best solutions. From infrastructure to energy to agriculture, these Activate Fellows are the bold thinkers who are building the next generation of science-focused companies to lead us into the future.”

The Houston fellows selected for the 2025 class include:

  • Jonathan Bessette, founder and CEO of KIRA, which uses its adaptive electrodialysis system to treat diverse water sources and reduce CO2 emissions
  • Victoria Coll Araoz, co-founder and chief science officer of Florida-based SEMION, an agricultural technology company developing pest control strategies by restoring crops' natural defenses
  • Eugene Chung, co-founder and CEO of Lift Biolabs, a biomanufacturing company developing low-cost, nanobubble-based purification reagents. Chung is completing his Ph.D. in bioengineering at Rice University.
  • Isaac Ju, co-founder of EarthFlow AI, which has developed an AI-powered platform for subsurface modeling, enabling the rapid scaling of carbon storage, geothermal energy and lithium extraction
  • Junho Lee, principal geotechnical engineer of Houston-based Deep Anchor Solutions, a startup developing innovative anchoring systems for floating renewables and offshore infrastructure

  • Becca Segel, CEO and founder of Pittsburgh-based FlowCellutions, which prevents power outages for critical infrastructure such as hospitals, data centers and the grid through predictive battery diagnostics
  • Joshua Yang, CEO and co‑founder of Cambridge, Massachusetts-based Brightlight Photonics, which develops chip-scale titanium: sapphire lasers to bring cost-effective, lab-grade performance to quantum technologies, diagnostics and advanced manufacturing

The program, led locally by Houston Managing Director Jeremy Pitts, has supported 296 Activate fellows since the organization was founded in 2015. Members have gone on to raise roughly $4 billion in follow-on funding, according to Activate's website.

Activate officially named its Houston office in the Ion last year.

Charlie Childs, co-founder and CEO of Intero Biosystems, which won both the top-place finish and the largest total investment at this year's Rice Business Plan Competition, was named to the Activate Anywhere cohort. Read more about the Boston, New York, Berkley and Activate Anywhere cohorts here.

Houston team’s discovery brings solid-state batteries closer to EV use

A Better Battery

A team of researchers from the University of Houston, Rice University and Brown University has uncovered new findings that could extend battery life and potentially change the electric vehicle landscape.

The team, led by Yan Yao, the Hugh Roy and Lillie Cranz Cullen Distinguished Professor of Electrical and Computer Engineering at UH, recently published its findings in the journal Nature Communications.

The work deployed a powerful, high-resolution imaging technique known as operando scanning electron microscopy to better understand why solid-state batteries break down and what could be done to slow the process.

“This research solves a long-standing mystery about why solid-state batteries sometimes fail,” Yao, corresponding author of the study, said in a news release. “This discovery allows solid-state batteries to operate under lower pressure, which can reduce the need for bulky external casing and improve overall safety.”

A solid-state battery replaces liquid electrolytes found in conventional lithium-ion cells with a solid separator, according to Car and Driver. They also boast faster recharging capabilities, better safety and higher energy density.

However, when it comes to EVs, solid-state batteries are not ideal since they require high external stack pressure to stay intact while operating.

Yao’s team learned that tiny empty spaces, or voids, form within the solid-state batteries and merge into a large gap, which causes them to fail. The team found that adding small amounts of alloying elements, like magnesium, can help close the voids and help the battery continue to function. The team captured it in real-time with high-resolution videos that showed what happens inside a battery while it’s working under a scanning electron microscope.

“By carefully adjusting the battery’s chemistry, we can significantly lower the pressure needed to keep it stable,” Lihong Zhao, the first author of this work, a former postdoctoral researcher in Yao’s lab and now an assistant professor of electrical and computer engineering at UH, said in the release. “This breakthrough brings solid-state batteries much closer to being ready for real-world EV applications.”

The team says it plans to build on the alloy concept and explore other metals that could improve battery performance in the future.

“It’s about making future energy storage more reliable for everyone,” Zhao added.

The research was supported by the U.S. Department of Energy’s Battery 500 Consortium under the Vehicle Technologies Program. Other contributors were Min Feng from Brown; Chaoshan Wu, Liqun Guo, Zhaoyang Chen, Samprash Risal and Zheng Fan from UH; and Qing Ai and Jun Lou from Rice.
