Fifty-one scientists and professors from Houston-area universities and institutions were named among the most cited in the world for their research in medicine, materials sciences and an array of other fields.

The Clarivate Highly Cited Researchers considers researchers who have authored multiple "Highly Cited Papers" that rank in the top 1percent by citations for their fields in the Web of Science Core Collection. The final list is then determined by other quantitative and qualitative measures by Clarivate's judges to recognize "researchers whose exceptional and community-wide contributions shape the future of science, technology and academia globally."

This year, 6,868 individual researchers from 60 different countries were named to the list. About 38 percent of the researchers are based in the U.S., with China following in second place at about 20 percent.

However, the Chinese Academy of Sciences brought in the most entries, with 258 researchers recognized. Harvard University with 170 researchers and Stanford University with 141 rounded out the top 3.

Looking more locally, the University of Texas at Austin landed among the top 50 institutions for the first time this year, tying for 46th place with the Mayo Clinic and University of Minnesota Twin Cities, each with 27 researchers recognized.

Houston once again had a strong showing on the list, with MD Anderson leading the pack. Below is a list of the Houston-area highly cited researchers and their fields.

Houston research: How social pressures are affecting digital product evaluations

houston voices

Theoretically, product evaluations should be impartial and unbiased. However, this assumption overlooks a crucial truth about product evaluators: They are human beings who are concerned about maintaining credibility with their audience, especially their peer evaluators.

Because evaluators must also care about being perceived as legitimate yet skillful themselves, certain social pressures are at play that potentially influence their product reviews.

Research by Minjae Kim (Rice Business) and Daniel DellaPosta (Penn State) takes up the question of how evaluators navigate those pressures. They find that in some cases, evaluators uphold majority opinion to appear legitimate and authoritative. In other contexts, they offer a contrasting viewpoint so that they seem more refined and sophisticated.

Pretend a movie critic gives an uplifting review of a widely overlooked film. By departing from the aesthetic judgments of cinema aficionados, the reviewer risks losing credibility with their audience. Not only does the reviewer fail to understand this specific film, the audience might say; they fail to understand film and filmmaking, broadly.

But it’s also conceivable, in other situations, that the dissenting evaluator will come across as uniquely perceptive.

What makes the difference between these conflicting perceptions?

Partly, it depends on how niche or mainstream the product is. With large-audience products, Kim and DellaPosta hypothesize, evaluators are more willing to contradict widespread opinion. (Without a large audience, contradicting opinions are like the sound of a tree that falls in a forest without anyone nearby to hear.)

The perceived classiness of the product can affect the evaluator’s approach, as well. It’s easier to dissent from majority opinion on products deemed “lowbrow” than those deemed “highbrow.” Kim and DellaPosta suggest it’s more of a risk to downgrade a “highbrow” product that seems to require more sophisticated taste (e.g., classical music) and easier to downgrade a highly rated yet “lowbrow” product that seems easier to appreciate (e.g., a blockbuster movie).

Thus, the “safe spot” for disagreeing with established opinion is when a product has already been thoroughly and highly reviewed yet appears easier to understand. In that case, evaluators might sense an opportunity to stand out, rather than try to fit in. But disagreeing with something just for the sake of disagreeing can make people think you’re not a fair or reasonable evaluator. To avoid that perception, it might be better to agree with the high rating.

To test their hypotheses, Kim and DellaPosta used data from beer enthusiast site BeerAdvocate.com, an online platform where amateur evaluators review beers while also engaging with other users. Online reviewers publicly rate and describe their impressions of a variety of beers, from craft to mainstream.

The data set included 1.66 million user-submitted reviews of American-produced beers, including 82,077 unique beers, 4,302 brewers, 47,561 reviewers and 103 unique styles of beer. The reviews spanned from December 2000 to September 2015.

When the researchers compared scores given to the same beer over time, they confirmed their hypothesis about the conditions under which evaluators contradict the majority opinion. On average, reviewers were more inclined to contradict the majority opinions for a beer that had been highly rated and widely reviewed. When reviewers considered a particular brew to be a “lowbrow,” downgrading occurred to an even greater extent.

Kim and DellaPosta’s research has implications for both producers and consumers. Both groups should be aware of the social dynamics involved in product evaluation. The research suggests that reviews and ratings are as much about elevating the people who make them as they are about product quality.

Making evaluators identifiable and non-anonymous may help increase accountability for what they say online — a seemingly positive thing. But Kim and DellaPosta reveal a potential downside: Knowing who evaluators are, Kim says, “might warp the ratings in ways that depart from true objective quality.”

Houston researcher tapped for prestigious fellowship for offshore safety innovation

big win

A University of Houston professor has been selected by a national organization to “contribute to the understanding, management and reduction of systemic risk in offshore energy activities.”

The Gulf Research Program of the National Academies of Sciences, Engineering, and Medicine announced that Harish Krishnamoorthy, assistant professor of electrical and computer engineering at the University of Houston, is one of four selected early-career research fellows in the Offshore Energy Safety track. Krishnamoorthy is the first researcher from UH selected for the recognition.

“I am happy and honored to be the first one, but hopefully there will be a lot more in the coming years,” Krishnamoorthy says in a UH news release.

The award, which isn't granted based on a specific project, includes a $76,000 grant, mentor support, and access to a network of current and past cohorts.

Created in 2013, the program is an independent, science-based program founded as part of legal settlements with the companies involved in the 2010 Deepwater Horizon disaster. Its goal is "to enhance offshore energy system safety and protect human health and the environment by catalyzing advances in science, practice and capacity, generating long-term benefits for the Gulf of Mexico region and the nation," the release reads.

“These exceptional individuals are working hard to pursue new research, technical capabilities, and approaches that address some of the greatest challenges facing the Gulf and Alaska regions today,” says Karena Mary Mothershed, senior program manager for the Gulf Research Program’s Board on Gulf Education and Engagement. “We are incredibly excited to announce these new Early-Career Research Fellows, and to continue supporting them as they make lasting impacts.”

Krishnamoorthy, who also serves as associate director of the Power Electronics, Microgrids and Subsea Electric Systems Center at UH, has expertise is in power electronics, power converters, and offshore technologies. His research interests include high-density power conversion for grid interface of energy systems, machine learning-based methods for improvement in quality and reliability of power electronics, advanced electronics and control for mission-critical applications.

According to Krishnamoorthy, there are around 1,500 offshore rigs — with a large amount located North Sea and the Gulf of Mexico. There's a need to improve existing systems, according to Krishnamoorthy, and this process of evolving the grid comes with safety risks and challenges.

“When there are so many electronics involved, safety and reliability are going to be very critical,” Krishnamoorthy says in he release. “I have been looking at safety aspects a lot in my research as well as how to connect subsea oil and gas systems with offshore renewable systems.”

In 2022, Krishnamoorthy was recognized as an OTC Emerging Leader at the Offshore Technology Conference for his contributions to offshore safety and workforce development in offshore, as well as reducing the carbon emissions.

Houston research: The future of decision making in energy operations

houston voices

Real options represent the decisions companies can make in the face of evolving risk. In the energy and commodity industries, real options are ubiquitous, including the extraction, processing and refinement, storage, and transportation of natural resources. These choices are influenced by ever-changing market and environmental conditions.

Because of these uncertainties, the energy industry has been a key focus of the operations literature on real options. Rice Business professor Nicola Secomandi, along with University of Illinois at Chicago College of Business Administration professor Selvaprabu Nadajarah, were recently invited by the European Journal of Operational Research to conduct a review of the operations literature on real options in energy. Their review included 80 papers across 10 journals active in the field. The research was mostly conducted during Secomandi’s time at the Tepper School of Business at Carnegie Mellon University.

The review examined how often different types of energy and methods of studying related business processes appeared in the operations literature. Nearly a quarter of the papers considered natural gas, more often than any other energy type. Natural gas storage was the most studied process, while the transport and sale of natural gas were less discussed.

While only 10 percent of the papers focused on electricity by itself, mostly in the context of battery management, electricity was discussed alongside emissions and the environment in 22.5 percent of the papers—almost as often as natural gas. About 11 percent of the papers examined both electricity and natural gas.

Roughly 21 percent of the papers focused on crude oil and refined products. Exploration, development, and abandonment of crude oil fields were common topics, while work on crude oil refining and gasoline logistics was rarer.

The review looked at the frequency of use of five categories: real option types, valuation methodologies, model formulations, price risk dynamics, and optimization schemes. Timing options, which irreversibly change the status of an asset when exercised, and switching options, which involve reversible changes, appeared with about equal frequency. Of the valuation methodologies, risk neutral valuation was employed the most often, appearing in nearly 78 percent of the papers. Model formulations were divided mainly between Markov decision processes, which assume that decisions are made at set times, and stochastic optimal control models, which assume that decisions are made continuously. About 63 percent of the papers discussed Markov decision processes, but at nearly 34 percent, stochastic optimal control models haven’t been entirely left out of the literature. Almost 75 percent of the papers formulated models based on spot prices as opposed to futures prices, and over 80 percent adopted normal distribution models, either alone or in combination with other models. Approximate solution approaches dominated within optimization schemes, appearing in 71 percent of the papers.

While several energy sources and analysis tools have been discussed in the literature, the possibilities for future research remain broad. The transition to clean energy sources may increase the complexity of already intricate operations. Its modeling and analysis may require more advanced models than existing ones.

We're living in the age of machine learning and artificial intelligence. Miguel Tovar/University of Houston

Now is the time to expand machine learning, says Houston researcher

Houston voices

One might not expect the game of checkers to have anything to do with artificial intelligence, but the game really marked the beginning of machine learning in 1959. Pioneered by an MIT professor named Arthur Lee Samuel, it was discovered that teaching a simple strategy game to a computer is not so simple when every move needs to be anticipated.

Smart machines Additionally, in a Forbes article about the difference between artificial intelligence and machine learning, Bernard Marr comments, "Artificial Intelligence is the broader concept of machines being able to carry out tasks in a way that we would consider 'smart'. And, machine learning is a current application of AI based around the idea that we should really just be able to give machines access to data and let them learn for themselves."

That's the premise of many a movie involving computers which become sentient, but is it really science fiction anymore?

Meet the new boss

Teaching a computer to think like a human is advantageous and includes the added bonus of increased speed. Computers aren't biased, either — which is why huge corporations, such as Unilever, use computers to thin out their first wave of applicants. You actually interview with a bot when you begin the employment process there.

Cause and effect AI and ML are often used in cybersecurity efforts — at least one would suppose. But in Security magazine, Jordan Mauriello writes: "AI/ML cannot do causation." That means artificial intelligence cannot, at this point in time, tell you why something happened. The why? is best left to experts who deal with game theory and other ways of determining how to defend against hypothetical attacks.

Get in on the ground floor

The field is growing and students at colleges across the country are beginning to train for careers in it in droves.

"America's top colleges are ramping up their research efforts and developing concentrations for their computer science degree programs to accommodate this high-tech field," writes Great Value Colleges on their blog. It looks as though this discipline is on an upward trajectory and shows no sign of slowing down.

Houston ranks among 15 U.S. hot spots for women in tech

Ranking It

Houston is soaring among the best places in the U.S. for women in tech, a new report says. Houston ranked No. 15 nationwide in SmartAsset's new report, "Best and Worst Cities for Women in Tech — 2026 Study," which compared the 50 biggest U.S. cities across four metrics:

  • Gender pay gap — women's median earnings as a percentage of men’s median earnings in tech
  • The share of all tech workers that are women
  • The overall concentration of employment for tech workers, defined as "tech workers as a share of the local workforce"
  • Women tech workers’ median earnings, adjusted for regional price parity
For the purpose of the study, tech workers are defined as "city residents employed in computer and mathematical occupations." The study's findings show that fewer than 9,500 tech workers in Houston are women, or 25.6 percent of the total tech workforce in the city. In total, tech workers in general make up less than 3 percent of the Houston workforce.Despite the high ranking, women tech workers in Houston have a sizeable gap to cross to receive equal pay compared to their male counterparts in the same industry. Women tech workers make just over $97,000 in median earnings after adjusting for regional price parity, which is only 93 percent of what male tech workers make, SmartAsset found.

There are only two U.S. cities where women in tech earn more than what their male counterparts: Miami and Memphis, Tennessee. Women tech workers in Miami make an adjusted $88,650 in median earnings, or 101.7 percent of what men in tech make. In Memphis, women make $84,718 in adjusted earnings, or 101.5 percent of what men in tech earn.

The findings also assert that women remain underrepresented in the nation's overall tech sector, despite making up nearly half of the total workforce. Only 22.6 percent of the country's tech labor force is made up of women, according to the Equal Employment Opportunity Commission."Opportunities for women in tech can vary considerably by location, and these differences shape access to jobs, career advancement and earning potential," the report's author wrote. "In some places, women account for a larger share of tech workers, face narrower pay gaps and enjoy a stronger local labor market. In others, they may encounter a more challenging career environmentThe six other Texas cities that earned spots in the report are Austin (No. 6), Fort Worth (No. 26), Dallas (No. 32), Arlington (No. 38), San Antonio (No. 42), and El Paso (No. 49).

The top 10 best U.S. cities for women in tech are:

  • No. 1 – San Jose, California
  • No. 2 – Seattle, Washington
  • No. 3 – San Francisco, California
  • No. 4 – Atlanta, Georgia
  • No. 5 – Baltimore, Maryland
  • No. 6 – Austin, Texas
  • No. 7 – Oakland, California
  • No. 8 – Portland, Oregon
  • No. 9 – Boston, Massachusetts
  • No. 10 – Minneapolis, Minnesota

Five female-founded businesses have been named finalists for the 2026 award. This year's finalists, selected by our esteemed panel of judges, range from an AI startup for C-Suite execs to a company developing semi-autonomous crawler robots for corrosion detection.

Read more about these innovative startups and the visionary female founders behind them below. The 2026 winners will be announced on InnovationMap.com in mid-November.

Adair

Artificial intelligence startup Adair uses computational linguistics and behavioral economics to measure, model and quantify the impact of spoken and written language on firm valuation and stock prices. The company works with C-Suite executives of public companies on high-stakes communications before they go live.

The company was founded last year by CEO Kathleen Perley, CPO Alex Duong and CTO Anthony Grivet. It raised $5.6 million earlier this year, according to its application.

ARIX Technologies

Energytech startup ARIX Technologies has developed a semiautonomous VENUS crawler robot to detect corrosion under insulation before it becomes a failure. The robots climb insulated piping in refineries, chemical plants and energy facilities to capture inspection data without removing insulation or building scaffolding. ARIX's inspection portal then turns information from the inspection into data a company can act on.

ARIX was founded in 2017 by Dianna Liu, who serves as director, and Head of Product Petter Wehlin. Craig Malloy serves as CEO. The company has raised more than $22 million in seed funding and a Series A round, according to its application.

Bairitone Health

Healthtech startup Bairitone Health is bringing anatomy imaging for sleep apnea to the home environment. The company's platform maps users' anatomy during natural sleep using a facial patch to determine the root cause of airway obstruction. It then offers effective therapies for each patient.

The company was founded in 2022 in the Texas Medical Center's Biodesign program by CEO Meagan Pitcher, CTO Onur Kilic and chief medical officer Britt Cross. It was a member of Activate Houston's inaugural cohort and has participated in numerous accelerators and incubators. The company raised an oversubscribed seed round for $2.4 million earlier this year and received Breakthrough Device Designation from the Food and Drug Administration in April.

FlowCellutions

Energytech startup FlowCellutions is developing a chemistry-agnostic diagnostics platform for flow and metal-air batteries supporting data centers and critical infrastructure. The platform is designed to help reduce operating costs, prevent failures and costly downtime, and extend battery lifetime from approximately seven years to more than 30 years. It has deployed four paid pilots and plans to take insights from the programs to develop its next-gen sensor platform technology.

CEO Becca Segel founded the company in 2022. It is a member of Greentown Labs, and Segel was a 2025 Activate Fellow. The company has raised over $2 million in non-dilutive funding and received a $1.5 million NSF SBIR Fast-Track award earlier this year.

ParaDocs Health

Healthtech startup ParaDocs Health is developing a clinical intelligence platform that helps doctors and care teams streamline administrative tasks and make better use of patient records. Its technology organizes fragmented clinical data into actionable insights, helping care teams identify gaps in care, assess patient risks and simplify documentation and reimbursement.

ParaDocs was founded in 2022 by CEO Dr. Dhini Nasution and CTO Dr. Omar Mohtar. The company participated in the TMCi Biodesign Program and raised a preseed round last year, according to its application.
