An engineering project at the University of Houston has been selected to join a $10 million effort to bring biopharmaceutical manufacturing into the future. The National Institute for Innovation in Manufacturing Biopharmaceuticals (NIIMBL) chose the lab of Richard Willson, Huffington-Woestemeyer Professor of chemical and biomolecular engineering at UH, as one of eight development projects that it will fund.

Willson and his team are working to develop a mix-and-read antibody measurement system that uses fluorescent materials to determine the amount of antibody present in a sample. The funding for this project is $200,000. This is the first grant UH has received from NIIMBL.

“In the course of the manufacturing processes, it's important to know the concentration of antibody in your sample and this measurement needs to be made many times in a typical manufacturing process,” said Willson in a press release. In the realm of fluorescents, he is also working to pioneer the use of glow sticks to detect biothreats for the U.S. Navy. His discoveries include a fluorescent material that emits one color of light when excited with another color of light.

Antibodies are what immune cells produce in response to alien substances such as bacteria and viruses. Lab-made antibodies, called monoclonal antibodies, have been in use since the 1980s. Antibody treatments now account for some of the world’s top-selling drugs.

“The nice thing about this reagent is that it becomes more fluorescent in the presence of antibodies, and you can determine the amount of antibody present in a sample by using it,” said Willson. “Along with our industrial partners Genentech, Agilent and Bristol Myers Squibb, we think that this might be a useful tool for people who do everything from growing the cells that make the antibodies, to determining concentrations of antibody before purifying them.”

Willson’s team also includes Katerina Kourentzi, research associate professor of chemical and biomolecular engineering at UH; Yan Chen, Agilent; Midori Greenwood-Goodwin, Genentech/Roche; and Mathura Raman, Bristol-Myers Squibb.

“One really distinguishing feature of this project is the tight coupling to industry,” said Kourentzi. “We got a lot of guidance from our industrial partners who volunteer to work with us through NIIMBL.” And through that, the technology could make it to the market in record time.

A Houston-based research team is tapping glow-in-the-dark materials to upgrade at-home rapid COVID-19 testing.

Researchers at the University of Houston have been rethinking the lateral flow assay (LFA) test used for at-home COVID-19 diagnostics. The traditional method indicates the sample's results with colored lines.

“We are making those lines glow-in-the-dark so that they are more detectable, so the sensitivity of the test is better,” says Richard Willson, a professor at the University of Houston, in a UH news release. He previously created a smartphone-based diagnostics app.

Willson's inspiration came from a familiar and nostalgic method — the glow-in-the-dark stars in a child's bedroom. In Willson's case, it was his daughter's bedroom, and within a few days his team of students and postdocs was designing a test featuring glowing nanoparticles made of phosphors.

The team evolved into a spin-off company called Clip Health, originally founded as Luminostics by two of the researchers. The operation is again evolving with new glowing applications.

“In this new development, there are two tricks. First, we use enzymes, proteins that catalyze reactions, to drive reactions that emit light, like a firefly. Second, we attached those light-emitting enzymes onto harmless virus particles, along with antibodies that bind to COVID proteins,” says Willson in the Royal Society of Chemistry’s journal Analyst.

The test now also can be read with a smartphone app. The group is also entertaining additional tests for other diseases.

“This technology can be used for detecting all kinds of other things, including flu and HIV, but also Ebola and biodefense agents, and maybe toxins and environmental contaminants and pesticides in food,” says Willson.

In addition to Willson, the original technology was explained in a paper with co-authors:

  • Katerina Kourentzi, University of Houston research associate professor of chemical and biomolecular engineering
  • Jacinta Conrad, Frank M. Tiller Associate Professor of Chemical and Biomolecular Engineering,
  • UH researchers Maede Chabi, Binh Vu, Kristen Brosamer, Maxwell Smith, and Dimple Chavan

Houston startup lands $10M to power up electrician staffing platform

money moves

Houston-based Buildforce, which provides a tech-enabled staff platform geared toward electricians and electrical contractors, has raised a $10 million Series A round led by Houston’s Saepio Capital.

Other investors in the round include Blue Heron Capital, Revolution’s Rise of the Rest Seed Fund, S3 Ventures and Chicago Ventures.

Buildforce says the funding will help fuel its national expansion and further development of its technology.

The startup, founded in 2019, connects electricians with electrical contractors for commercial and industrial construction projects. Buildforce’s mobile app helps electricians find and carry out work, and a web app helps electrical contractors find and manage electricians.

“This financing is a major milestone in furthering our mission to help people dedicated to a career in the construction trades lead more secure and fulfilling lives,” co-founder and CEO Moody Heard said in a news release.

Buildforce focuses solely on the electrical trade within the construction sector.

Nick Graziano, principal at Blue Heron, says the shortage of electricians is intensifying as demand for electricians accelerates, driven by data center construction, infrastructure development and energy transition initiatives.

The U.S. Bureau of Labor Statistics estimates the U.S. will need to hire about 80,000 new electricians per year through 2032 to catch up with demand. According to the National Electrical Contractors Association, the U.S. is grappling with a current shortage of 50,000 electricians.

A 2026 economic report from asset manager BlackRock says the electrical trade is expected to be the single fastest-growing employment category in the U.S. labor market over the next 10 years.

“Buildforce is capitalizing on a clear opportunity in America’s generational infrastructure buildout. We believe their mission to use technology to improve lives in the construction space will allow them to make a positive long-term impact on a large and important labor market,” added Jaan Bains, managing partner at Saepio Capital.

Venus Aerospace adds government, C-suite leaders following $91M raise​

new leaders

Fresh off its $91 million Series B, Houston-based Venus Aerospace has made several key additions and promotions to its leadership team.

The company says its expanded team will help it deploy its high-thrust rotating detonation rocket engine (RDRE), which completed its first U.S. flight test last summer.

"We flew the world's first high-thrust RDRE in just over four years on $80 million. We believe that makes it the fastest, most capital-efficient rocket engine program in history," Sassie Duggleby, co-founder and CEO of Venus Aerospace, said in a news release. "Adding this talent to our leadership team is how we bring that same discipline to the company itself, as we scale to meet the technical needs of defense and space customers who need range and speed legacy systems can't deliver."

The key hires include:

Lane Bodian, Vice President of Public Policy

Bodian previously served as the Principal Deputy Assistant Secretary of Defense for Legislative Affairs at the Pentagon.

Dan Rebnord, Director of Federal Government Relations

Rebnord most recently served as Senior Policy Advisor to a member of the Senate Armed Services Committee and previously worked in the Office of Legislative Affairs at the Department of Defense and as Staff Director for a national security subcommittee in the House of Representatives. Rebnord and Bodian will lead Venus' work with government stakeholders.

Tom Barron, Chief Operating Officer

Barron was promoted from his role as vice president of operations for Venus Aerospace. Before his time at Venus, he served as Special Assistant to the Secretary of Defense and consulted aerospace clients at McKinsey & Company. He also served as a U.S. Army Infantry and Special Forces officer.

Nick Cardwell, Chief Product Officer

Cardwell was promoted from his role as vice president of research and development. He previously held product and technology leadership roles at VC-backed tech companies in the San Francisco Bay Area and Austin.

Venus also named Cameron Taylor as its new vice president of operations, Sarah Boland Heine as its head of communications, Matt Stohr as its head of business development, and Sheila Menz as general counsel.

The company also announced a joint technology development agreement to advance the RDRE with defense giant Lockheed Martin last week. Through the partnership, Venus and Lockheed will focus on evaluating the RDRE's propulsion architecture in defense systems, specifically for precision fires applications where weapons are designed to accurately strike targets at long distances.

Lockheed Martin Ventures, the investment arm of the aerospace and defense contractor, is an investor in Venus Aerospace.

"Lockheed Martin is focused on rapidly delivering advanced capabilities that strengthen deterrence and provide decisive advantages for the warfighter," Tim Cahill, president, Lockheed Martin Missiles and Fire Control, said in a news release. "Our collaboration with Venus Aerospace allows us to evaluate a promising propulsion technology and determine how it can be integrated into future precision fires solutions. Efforts like this help accelerate innovation, reduce risk and shorten the path from emerging technology to operational capability."

Venus' RDRE is expected to enable vehicles to travel four to six times the speed of sound from a conventional runway and is about 15 percent more efficient than traditional alternatives, according to the company.

Venus says the reusable, affordable and scalable RDRE is designed with a "common propulsion architecture" that can work for multiple industries and mission types. The company has previously estimated that the hypersonic market is projected to surpass $12 billion by 2030.
