Anyone can die of sepsis. The number one killer in hospitals has a reputation for felling the infirm and elderly, but while the immunocompromised are at highest risk, sepsis isn’t that selective.

Take 12-year-old Rory Staunton. In 2012, the healthy boy scratched his arm diving for a ball in gym class at his school in Jackson Heights, NY. Bacteria entered his arm through the cut and he died days later of septic shock.

His story is not unique. Physician Sarma Velamuri saw this firsthand in his internal medicine practice at St. Luke’s Health Center and his residency at Baylor, both in Houston. But it really struck home when he watched helplessly as a friend’s 22-year-old daughter lost her life to sepsis. He had to tell his friend that she would not be coming home.

“There are 300,000-plus people a year who die of sepsis,” says Velamuri. “It’s important that people understand it’s not just those who are most susceptible to infections.”

This fact is not only unfortunate, but preventable. And that’s why Velamuri, who describes himself as “a recovering hospitalist,” co-founded Luminare in 2014. A full-time CEO since 2017, Velamuri, who runs the company with co-founder and CTO Marcus Rydberg, is based in the TMC Innovation Factory.

“Because of the complex workflows in hospitals, sometimes it takes 10 people to get the patient the care they need,” Velamuri explains.

And because of the pervasiveness of sepsis, it’s important to screen every patient who enters an institution before it gets to that point.

Luminare’s technology allows nurses, who are notoriously spread thin, to automatically screen patients in 10 seconds using 50 different parameters.

“We’re looking at a vast amount of data simultaneously,” says Velamuri. “We’re not generating any new data, we’re taking data that exists and shining a light on it.”

In 2020, the technology found a new application when Velamuri and his team created a version of Luminare that helped with the hospital workflow surrounding COVID PCR testing and vaccine management. Since then, it has also been used to help identify and treat monkeypox.

Though Velamuri says he doesn’t want to distract Luminare from its goal of making sepsis the number-two killer in hospitals, he is also aware that his technology can be instrumental in identifying and treating patients at risk for countless other maladies, including heart failure and stroke, and even helping with oncology workflows.

Velamuri says that his team is Luminare’s biggest strength, far more than the AI that they have designed.

“I have this saying that AI is a great servant but a terrible master. It doesn’t solve the problem,” says Velamuri.

Though the company is distributed as far afield as Stockholm, about half of its people live and work in Houston. Of the company’s placement in TMC’s Innovation Factory, Velamuri says, “They’ve been tremendous partners to us. The company would not be as successful today without their supportive partnership.” Not least of that is working with in the same space as other founders who can share their expertise as easily as a trip to the coffee machine.

And the company is growing quickly. Last year, Luminare participated in Cedars-Sinai’s accelerator program. Thanks to that partnership, the hospital is now using Luminare’s technology for sepsis screening. The team is working to partner with even more large hospital systems on solutions for one of the health industry’s biggest problems. And data that shows that Luminare can be the path to preventing death from hospitals’ most prolific killer.

Houston researcher builds radar to make self-driving cars safer

eyes on the road

A Rice University researcher is giving autonomous vehicles an “extra set of eyes.”

Current autonomous vehicles (AVs) can have an incomplete view of their surroundings, and challenges like pedestrian movement, low-light conditions and adverse weather only compound these visibility limitations.

Kun Woo Cho, a postdoctoral researcher in the lab of Rice professor of electrical and computer engineering Ashutosh Sabharwal, has developed EyeDAR to help address such issues and enhance the vehicles’ sensing accuracy. Her research was supported in part by the National Science Foundation.

The EyeDAR is an orange-sized, low-power, millimeter-wave radar that could be placed at streetlights and intersections. Its design was inspired by that of the human eye. Researchers envision that the low-cost sensors could help ensure that AVs always pick up on emergent obstacles, even when the vehicles are not within proper range for their onboard sensors and when visibility is limited.

“Current automotive sensor systems like cameras and lidar struggle with poor visibility such as you would encounter due to rain or fog or in low-lighting conditions,” Cho said in a news release. “Radar, on the other hand, operates reliably in all weather and lighting conditions and can even see through obstacles.”

Signals from a typical radar system scatter when they encounter an obstacle. Some of the signal is reflected back to the source, but most of it is often lost. In the case of AVs, this means that "pedestrians emerging from behind large vehicles, cars creeping forward at intersections or cyclists approaching at odd angles can easily go unnoticed," according to Rice.

EyeDAR, however, works to capture lost radar reflections, determine their direction and report them back to the AV in a sequence of 0s and 1s.

“Like blinking Morse code,” Cho added. “EyeDAR is a talking sensor⎯it is a first instance of integrating radar sensing and communication functionality in a single design.”

After testing, EyeDAR was able to resolve target directions 200 times faster than conventional radar designs.

While EyeDAR currently targets risks associated with AVs, particularly in high-traffic urban areas, researchers also believe the technology behind it could complement artificial intelligence efforts and be integrated into robots, drones and wearable platforms.

“EyeDAR is an example of what I like to call ‘analog computing,’” Cho added in the release. “Over the past two decades, people have been focusing on the digital and software side of computation, and the analog, hardware side has been lagging behind. I want to explore this overlooked analog design space.”

12 winners named at CERAWeek clean tech pitch competition in Houston

top teams

Twelve teams from around the country, including several from Houston, took home top honors at this year's Energy Venture Day and Pitch Competition at CERAWeek.

The fast-paced event, held March 25, put on by Rice Alliance, Houston Energy Transition Initiative and TEX-E, invited 36 industry startups and five Texas-based student teams focused on driving efficiency and advancements in the energy transition to present 3.5-minute pitches before investors and industry partners during CERAWeek's Agora program.

The competition is a qualifying event for the Startup World Cup, where teams compete for a $1 million investment prize.

PolyJoule won in the Track C competition and was named the overall winner of the pitch event. The Boston-based company will go on to compete in the Startup World Cup held this fall in San Francisco.

PolyJoule was spun out of MIT and is developing conductive polymer battery technology for energy storage.

Rice University's Resonant Thermal Systems won the second-place prize and $15,000 in the student track, known as TEX-E. The team's STREED solution converts high-salinity water into fresh water while recovering valuable minerals.

Teams from the University of Texas won first and second place in the TEX-E competition, bringing home $25,000 and $10,000, respectively. The student winners were:

Companies that pitched in the three industry tracts competed for non-monetary awards. Here are the companies named "most-promising" by the judges:

Track A | Industrial Efficiency & Decarbonization

Track B | Advanced Manufacturing, Materials, & Other Advanced Technologies

  • First: Licube, based in Houston
  • Second: ZettaJoule, based in Houston and Maryland
  • Third: Oleo

Track C | Innovations for Traditional Energy, Electricity, & the Grid

The teams at this year's Energy Venture Day have collectively raised $707 million in funding, according to Rice. They represent six countries and 12 states. See the full list of companies and investor groups that participated here.
