For Alex Han, it all started with peanut butter.

Han was a high school student in Korea when he learned that the spread is a pure odorant that could be used to test smell in each hemisphere of the brain—issues on the left side was thought to be a predictor for Alzheimer’s disease. He later learned that the method wasn’t as airtight as previously thought, but Han was hooked. Alzheimer’s research became the teenager’s passion. While still in high school, Han began volunteering for Alzheimer’s Los Angeles, translating their brochures into Korean.

When it came time to choose a college, Han says Rice University appealed to him for many reasons.

“I loved the atmosphere. I loved the campus—it’s so beautiful. The diverse food, the people, I even liked the highway,” he says of Houston. “In Korea, everything is so close and compact. I loved the whole scenario of the city.”

A scholarship was also part of the appeal, as well as the pull of the world’s largest medical center. Han’s instincts were correct. Now, a junior at Rice, he has been working at renowned geneticist Huda Zoghbi’s Baylor College of Medicine lab for almost two years.

But dividing his obligations between full-time studies and his wet lab position wasn’t enough to keep Han’s active mind occupied. Last May, the statistics and biochemistry student began another endeavor that uses both his specialties. It was then that he founded Biokind Analytics. The nonprofit was designed to explore how data science can support health care nonprofits.

Han reached out to Alzheimer’s Los Angeles to offer his data analysis services on a volunteer basis and was shocked that the association had never considered it before.

“I was really surprised—even small stores and restaurants use statistics to boost their profits. [Alzheimer’s Los Angeles] receive a couple million dollars every year in donations. They have data stores but hadn’t really capitalized yet in the area of analytics.”

Han, along with a small team of Rice students, including vice president Zac Andrews and development director Masha Zaitsev, made Alzheimer’s Los Angeles a pet project, analyzing geospatial trends in its donorship and interpreting the past year’s donation trends. “We wanted to see if the demand was the same in Houston. We found that this pattern was consistent. A lot of nonprofits are willing to have us analyze the data sets they’ve already been tracking and provide data analysis for healthcare nonprofits.”

Less than a year after Han established Biokind Analytics, the 501(c)(3) already has seven chapters on college campuses around the country. From UC Davis and San Diego in the West to Brown University and the University of Virginia on the East Coast, the data science students have helped a diverse range of medical nonprofits, mostly based in the Houston area. They run the gamut from ALS Association of Texas to Nora’s Home, which serves organ failure and transplant patients.

Biokind Analytics has now completed seven projects and analyzed $100 million in funds. Each student group includes four to six members, mostly majors in the worlds of statistics, data science, and biochemistry, all working with the help of faculty advisors. At a total of about 35 students nationwide, Han says that he’s dedicated to growing at a steady pace to avoid potentially expanding too fast, too soon.

Another question for the future is what will happen to Biokind Analytics when Han completes his undergraduate studies in 2024. He plans to continue his medical studies with the goal of one day becoming a physician specializing in Alzheimer’s who uses data analytics to aid in patient care. But no matter how active Han continues to be in the nonprofit he started, his stated attachment to the cause and a growing group of both student leaders and healthcare associations eager for their services are sure to keep Biokind Analytics active long after graduation.

How Houston innovators played a role in the historic Artemis II splashdown

safe landing

Research from Rice University played a critical role in the safe return of U.S. astronauts aboard NASA’s Artemis II mission this month.

Rice mechanical engineer Tayfun E. Tezduyar and longtime collaborator Kenji Takizawa developed a key computational parachute fluid-structure interaction (FSI) analysis system that proved vital in NASA’s Orion capsule’s descent into the Pacific Ocean. The FSI system, originally developed in 2013 alongside NASA Johnson Space Center, was critical in Orion’s three-parachute design, which slowed the capsule as it returned to Earth, according to Rice.

The model helped ensure that the parachute design was large enough to slow the capsule for a safe landing while also being stable enough to prevent the capsule from oscillating as it descended.

“You cannot separate the aerodynamics from the structural dynamics,” Tezduyar said in a news release. “They influence each other continuously and even more so for large spacecraft parachutes, so the analysis must capture that interaction in a robustly coupled way.”

The end result was a final parachute system, refined through NASA drop tests and Rice’s computational FSI analysis, that eliminated fluctuations and produced a stable descent profile.

Apart from the dynamic challenges in design, modeling Orion’s parachutes also required solving complex equations that considered airflow and fabric deformation and accounted for features like ringsail canopy construction and aerodynamic interactions among multiple parachutes in a cluster.

“Essentially, my entire group was dedicated to that work, because I considered it a national priority,” Tezduyar added in the release. “Kenji and I were personally involved in every computer simulation. Some of the best graduate students and research associates I met in my career worked on the project, creating unique, first-of-its-kind parachute computer simulations, one after the other.”

Current Intuitive Machines engineer Mario Romero also worked on Orion during his time at NASA. From 2018 to 2021, Romero was a member of the Orion Crew Capsule Recovery Team, which focused on creating likely scenarios that crewmembers could encounter in Orion.

The team trained in NASA’s 6.2-million-gallon pool, using wave machines to replicate a range of sea conditions. They also simulated worst-case scenarios by cutting the lights, blasting high-powered fans and tipping a mock capsule to mimic distress situations. In some drills, mock crew members were treated as “injured,” requiring the team to practice safe, controlled egress procedures.

“It’s hard to find the appropriate descriptors that can fully encapsulate the feeling of getting to witness all the work we, and everyone else, did being put into action,” Romero tells InnovationMap. “I loved seeing the reactions of everyone, but especially of the Houston communities—that brought me a real sense of gratitude and joy.”

Intuitive Machines was also selected to support the Artemis II mission using its Space Data Network and ground station infrastructure. The company monitored radio signals sent from the Orion spacecraft and used Doppler measurements to help determine the spacecraft's precise position and speed.

Tim Crain, Chief Technology Officer at Intuitive Machines, wrote about the experience last week.

"I specialized in orbital mechanics and deep space navigation in graduate school,” Crain shared. “But seeing the theory behind tracking spacecraft come to life as they thread through planetary gravity fields on ultra-precise trajectories still seems like magic."

UH breakthrough moves superconductivity closer to real-world use

Energy Breakthrough

University of Houston researchers have set a new benchmark in the field of superconductivity.

Researchers from the UH physics department and the Texas Center for Superconductivity (TcSUH) have broken the transition temperature record for superconductivity at ambient pressure. The accomplishment could lead to more efficient ways to generate, transmit and store energy, which researchers believe could improve power grids, medical technologies and energy systems by enabling electricity to flow without resistance, according to a release from UH.

To break the record, UH researchers achieved a transition temperature 151 Kelvin, which is the highest ever recorded at ambient pressure since the discovery of superconductivity in 1911.

The transition temperature represents the point just before a material becomes superconducting, where electricity can flow through it without resistance. Scientists have been working for decades to push transition temperature closer to room temperature, which would make superconducting technologies more practical and affordable.

Currently, most superconductors must be cooled to extremely low temperatures, making them more expensive and difficult to operate.

UH physicists Ching-Wu Chu and Liangzi Deng published the research in the Proceedings of the National Academy of Sciences earlier this month. It was funded by Intellectual Ventures and the state of Texas via TcSUH and other foundations. Chu, founding director and chief scientist at TcSUH, previously made the breakthrough discovery that the material YBCO reaches superconductivity at minus 93 K in 1987. This helped begin a global competition to develop high-temperature superconductors.

“Transmitting electricity in the grid loses about 8% of the electricity,” Chu, who’s also a professor of physics at UH and the paper’s senior author, said in a news release. “If we conserve that energy, that’s billions of dollars of savings and it also saves us lots of effort and reduces environmental impacts.”

Chu and his team used a technique known as pressure quenching, which has been adapted from techniques used to create diamonds. With pressure quenching, researchers first apply intense pressure to the material to enhance its superconducting properties and raise its transition temperature.

Next, researchers are targeting ambient-pressure, room-temperature superconductivity of around 300 K. In a companion PNAS paper, Chu and Deng point to pressure quenching as a promising approach to help bridge the gap between current results and that goal.

“Room-temperature superconductivity has been seen as a ‘holy grail’ by scientists for over a century,” Rohit Prasankumar, director of superconductivity research at Intellectual Ventures, said in the release. “The UH team’s result shows that this goal is closer than ever before. However, the distance between the new record set in this study and room temperature is still about 140 C. Closing this gap will require concerted, intentional efforts by the broader scientific community, including materials scientists, chemists, and engineers, as well as physicists.”
