Taking control of your health can be a difficult path to walk on your own. A new startup, created by eight female Rice University students, is aimed at wading through the health care system.

The Healthcare Navigator is a platform that helps users to learn about not just treatment options, but also the financial bearings thereof.

“About 88 percent of Americans aren’t health literate,” founder and president Kayla Grimes says in a news release. “It’s very hard for them to navigate health care in the way to get the best benefit for it, so what our platform will do is essentially give them the tools and resources to confidently navigate the health care system. We also help with price transparency specifically.”

The multidisciplinary team includes women majoring in pre-med, computer science, medical humanities, art and business. According to Grimes (a rising senior business major), the seed for the idea’s success was planted two years ago when she was volunteering for the National Patient Advocacy Foundation.

“They told me, ‘If you do this right, this could actually change everything in health care,’” she remembers.

Now she and her team have an app, as well as an accessible website, composed of several features all meant to make it easier to save money — and users’ health. The features are:

  • Cost Compass, which compares procedure costs across local hospitals, enabling users to shop around and save money.
  • Care Genius AI, an AI chatbot that helps users to negotiate medical bills and answers health care system questions.
  • Patient Power Modules, which are interactive educational videos that make understanding the health care system easy and engaging.
  • Pocket Doc, which helps consumers find the best providers for them based on location, ratings and quality metrics.
  • Pulse Check Alert keeps users informed on important health care news and patient insights.
  • Care Manager streamlines users’ health care needs and goals in one convenient place.

Grimes says that she hopes that users will skip Google reviews and go straight to their Pocket Doc, which includes information on hospitals, clinics, urgent care centers and freestanding emergency rooms.

“We have that in the system, so that you can actually see useful metrics instead of just going on Google reviews and reading their readmission rate — we’re going to explain what’s a good readmission rate and what’s a bad readmission rate,” she says. “That’s the whole point: We’re not just going to give you these metrics, we’re also going to give you some benchmarks, so you can make the decision for yourself.”

When dealing with your health, knowledge is certainly power, and Healthcare Navigator is bestowing a new kind of power on its users.

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.
