Google program plants software expert at Houston-area university

meet the faculty

Computer science students at Prairie View A&M University are gaining firsthand knowledge this semester from a Google software engineer.

Prairie View A&M is one of 14 historically black colleges and universities (HBCUs) and Hispanic-serving schools that are benefiting this fall from the Google residency program. Since being founded in 2013, the program has enabled more than 8,000 college students across the country to absorb knowledge from Google tech professionals.

The Google program addresses a nationwide gap in tech diversity.

A 2023 report from CompTIA, a trade group for the tech industry, shows Black professionals make up 12 percent of the U.S. workforce but eight percent of tech occupations, while Hispanic professionals represent 17 percent of the U.S. workforce but eight percent of tech occupations.

Prairie View A&M, an HBUC, is one of two Texas universities in this fall’s program. The other is the University of Texas at El Paso, a Hispanic-serving school. The main campus of Prairie View A&M is roughly 45 miles northwest of Houston.

Google says Debnam is equipping students at Prairie View A&M “with the skills needed to enter the workforce, such as fundamental coding concepts, how to debug, and how to prepare for technical interviews.”

As a student in 2017, Debnam participated in the Google residency program at Hampton University, an HBCU in Hampton, Virginia. In a LinkedIn post, Debnam wrote that since then, “I always said to myself and others that if I could figure out a way to get into Google someday, I would make it a priority to try to be part of this program.”

After completing two Google internships and earning a bachelor’s degree in computer science from Hampton, Debnam joined the tech giant as a full-time software engineer in 2021.

“If you know me, you know I have a passion for tech, but an even deeper passion for working with students and being a resource in any way possible,” he wrote on LinkedIn.

Greentown Labs launches student-driven entrepreneurship program in Texas

back to school

The country's largest climatetech startup incubator and several schools are teaming up to prepare the next generation of clean energy innovators.

Greentown Labs, based in Boston and Houston, announced its new Texas Entrepreneurship Exchange for Energy (TEX-E) this week. The collaborative initiative aims to strengthen the student-driven entrepreneurship ecosystem in Houston, according to a news release, to focus on energy innovation. Greentown Labs, MIT’s Martin Trust Center for Entrepreneurship, and universities across Texas — including The founding institutions of TEX-E are Rice University, Texas A&M University, Prairie View A&M University, University of Houston, and The University of Texas at Austin — are collaborating on the project.

“Houston has long been known as the energy capital of the world, but to lead the world’s energy transition, the city must create a strong, vibrant innovation ecosystem to support the next generation of entrepreneurs and energy companies,” says Lara Cottingham, chief of staff at Greentown Labs, in the news release. “TEX-E will build upon Texas universities’ deep and long-standing connections to the energy industry by helping to attract and retain the world-class talent needed to supercharge Houston’s innovation ecosystem.”

The program, though based in Texas, will integrate both Greentown Labs locations, providing students with access to mentorship with incubator startups, networking events, career opportunities, and cross-learning with MIT.

“Boston and Houston might seem like an odd pairing, but they complement one another beautifully,” says Ben Soltoff, ecosystem builder and entrepreneur in residence at the Martin Trust Center for MIT Entrepreneurship, in the release. “The Boston area has a strong community-driven ecosystem around climate innovation, including MIT’s pioneering Climate and Energy Ventures Course in Cambridge, which has spawned over 30 companies. But often when MIT startups need to scale up, they look towards Texas, where they can find talent, space, and industry knowhow in spades.

"Together, these two regions are unstoppable,” he adds.

The five schools are just the beginning for the program, which plans to expand the collaboration over time. Locally, Houston area schools have collaborated with Greentown Houston since its opening over a year ago.

“The TEX-E collaboration will provide valuable opportunities to our students, and Houston is a natural location to create such an ecosystem,” says Ramanan Krishnamoorti, vice president for energy and innovation at the University of Houston, in the release. “Training new talent and supporting their pursuit of innovative ideas are vital in addressing the growing global need for affordable, reliable, and environmentally sustainable energy.”

For more information, students and educators should sign up for the TEX-E newsletter and attend an upcoming event at Greentown Houston. The next event at the incubator is the Climatetech Summit on November 2.

Shell forms $5M carbon capture research partnership with Houston-area university

struck a deal

Houston-based Shell Global Solutions and Prairie View A&M University signed a $5 million partnership this week that aims to foster innovative and effective carbon dioxide utilization and carbon capture methods.

The five-year research agreement will be headquartered out of the Historically Black University's College of Agriculture and Human Sciences. A portion of the $5 million will go toward building new infrastructure and state-of-the-art greenhouses on the university's nearly 700 acres of land devoted to farm research.

Shell staff members are also slated to collaborate on research projects developed at the site.

In addition to the $5 million partnership, Shell also pledged another $1 million to create a career pipeline for PVAMU students. The funds will go toward university infrastructure, retention programs, and work experience opportunities.

"[Shell's] comprehensive approach — involving infrastructure, research collaboration, internships and ongoing staff involvement — is especially welcome," Ruth J. Simmons, president of PVAMU, said in a statement.

The new research program is funded through Shell's Projects & Technology organization, which "helps to ensure that neither people nor nature are harmed during the construction and operation of Shell’s facilities, and it supports Shell’s carbon-management activities," according to the company's website.

Shell has launched more than 220 research and development projects through this branch of the organization over the years.

In 2019, the energy giant committed to a $10 million arrangement to launch the Carbon Hub at Rice University, a research initiative aimed at developing zero-emissions technologies. The hub made its first seven seed grants in August.

Shell is also an industry partner on the University of Houston's Data Science for Energy Transition project.

The partnership also marks a milestone for PVAMU as the first significant partnership under the university's new classification as a Research 2 Institution, according to PVAMU's website. The university attained its R2 Carnegie Classification, the second-highest ranking for research and higher education institutions in the country, earlier this month.

H-E-B leader gifts $5 million to historic Houston-area university for future students

HEB and PVAMU

The leader of the Lone Star State’s beloved H-E-B has bestowed a monumental gift upon a historic Houston-area university.

On November 17, Prairie View A&M University announced that H-E-B chairman Charles Butt — one of America’s favorite CEOs and member of one of Texas’ richest families — has donated $5 million to create Founders Scholarships for incoming PVAMU students.

“The $5 million gift will provide a permanent endowment to support students today and in the coming years,” a release notes. “Initially generating approximately $200,000 a year for scholarships, the fund will grow significantly in coming years, making even more available to support students.”

The scholarships will be available to students from public high schools in Texas graduating in the top quartile of their class, the release says. They must be incoming first-year students, enrolled in a full-time course load, and as scholarship recipients, they will benefit from “enrichment opportunities unique to their [Founders Scholarships] cohort.”

Scholarship disbursements will begin in fall 2022, a spokesperson confirms; the number of initial scholarships available has not been revealed.

“Charles Butt has been amazingly generous to our university. He has shown time and time again that he genuinely cares about the opportunities afforded to students at PV. We are indebted to him for his grace and his humanity,” says Ruth Simmons, president of PVAMU, in the release.

Prairie View A&M University is the second-oldest public institution of higher learning in the state and is one of Texas’ historically Black universities. It is located approximately 50 miles northwest of Houston and has a current enrollment of more than 8,000 undergraduate and graduate students.

Philanthropist gifts historic $50 million to Houston-area university

major gift

Historically Black universities have traditionally been overshadowed and underfunded compared to their non-Black collegiate counterparts. But now, a major public figure's game-changing gift has helped level the playing field for a beloved Houston-area school.

Noted author and philanthropist MacKenzie Scott (many know her as the former wife of Amazon CEO and billionaire Jeff Bezos) has donated a massive $50 million to Prairie View A&M University, the institution announced on December 15. The gift is the largest one-time endowment in the school's 144-year history.

Under terms of the donation, the funds can be used at the discretion of the president to support the needs of the university, per a press release. Administrators have chosen to designate $10 million of the total to create the Panther Success Grant Program, an effort to assist juniors and seniors with unpaid balances created by the financial challenges posed by COVID, the school announced.

"This is a historic gift for Prairie View, coming at a time when the university had already decided and begun to invest heavily in key areas to strengthen its academic programs and improve student success," said Ruth J. Simmons, president of Prairie View, in a statement. "The timing of this gift could therefore not be better."

Simmons adds in a statement that she had been in contact with Scott "about a matter not involving Prairie View," and thus was "stunned and, for a time speechless" when Scott's assistant phoned and revealed the donation.

Another whopping gift from Scott includes $18 million to the Greater Houston YMCA.

In a post on Medium, Scott notes that she and her advisers have disbursed over $4 billion in gifts to 384 organizations across all 50 states, Puerto Rico, and Washington D.C. over the last four months. This is in effort to "accelerate my 2020 giving through immediate support to people suffering the economic effects of the crisis," Scott writes.

Scott's generosity includes myriad Texas organizations and groups, including:

Easterseals of Greater Houston
Easterseals Rehabilitation Center, San Antonio
East Texas Food Bank
El Pasoans Fighting Hunger
Feeding the Gulf Coast
South Texas Food Bank
Southeast Texas Food Bank
Goodwill Houston
Goodwill Industries of Dallas
Goodwill Industries of East Texas
Goodwill Industries of Fort Worth
Goodwill Industries of San Antonio
Heart of Texas Goodwill Industries
Meals on Wheels Central Texas
Meals on Wheels Montgomery County
Meals on Wheels North Central Texas
Texas A&M International University

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.

New report ranks Houston as America's No. 2 least safe city

Ranking It

A new study contains bad news for Houston. A report from personal finance website SmartAsset ranks the Bayou City as the second-least safe city in the U.S. among cities with at least 250,000 residents.

Only Memphis ranked worse than Houston.

The 2026 study looked at 83 U.S. cities' violent crimes, property crimes, traffic deaths, and disaster risk.

Houston fared poorly in all four: 11.5 violent crimes per 1,000 residents, 42.9 property crimes per 1,000 residents, 11.6 traffic deaths per 100,000 residents, and “very high” risk for natural disasters, which makes sense in a city prone to tropical weather and flooding.

For all cities in the study, disaster risk and traffic deaths were measured at the county level.

Houston is the only Texas city to rank in the bottom 10. The other cities are:

1. Memphis, Tennessee
2. Houston, Texas
3. St. Louis, Missouri
4. San Francisco, California
5. Kansas City, Missouri
6. Albuquerque, New Mexico
7. Oakland, California
8. Nashville, Tennessee
9. Philadelphia, Pennsylvania
10. Detroit, Michigan

“While no major population center is entirely free from danger, some are more successful than others at creating environments where people can live, work and travel with confidence,” SmartAsset says.

Although this study paints Houston in a poor light, other reports take a more positive view. The "America's Best Cities" report from Canada-based real estate and tourism marketing firm Resonance Consultancy ranked as No. 9 in America out of 393 cities with a population of 500,000 or more. Houston also boasts Texas’ 10th best park system, according to its ParkScore Index.

While SmartAsset has bad news for Houston, the Dallas suburb of Plano ranked as the study’s second-safest big city. Compared to Houston, Plano fared well in three of the four categories: 1.5 violent crimes per 1,000 residents, 14.7 property crimes per 1,000 residents, and 6.9 traffic deaths per 100,000 residents. Its only shortcoming is a “relatively high” risk for natural disasters.

Elsewhere in Texas:

Fort Worth ranked No. 22
Austin ranked No. 26
San Antonio ranked No. 54
Dallas ranked No. 73
