Another Houston scientist has won one of the highly competitive National Science Foundation (NSF) CAREER Awards.

Lei Li, an assistant professor of electrical and computer engineering at Rice University, has received a $550,000, five-year grant to develop wearable, hospital-grade medical imaging technology capable of visualizing deep tissue function in real-time, according to the NSF. The CAREER grants are given to "early career faculty members who demonstrate the potential to serve as academic models and leaders in research and education."

“This is about giving people access to powerful diagnostic tools that were once confined to hospitals,” Li said in a news release from Rice. “If we can make imaging affordable, wearable and continuous, we can catch disease earlier and treat it more effectively.”

Li’s research focuses on photoacoustic imaging, which merges light and sound to produce high-resolution images of structures deep inside the body. It relies on pulses of laser light that are absorbed by tissue, leading to a rapid temperature rise. During this process, the heat causes the tissue to expand by a fraction, generating ultrasound waves that travel back to the surface and are detected and converted into an image. The process is known to yield more detailed images without dyes or contrast agents used in some traditional ultrasounds.

However, current photoacoustic systems tend to use a variety of sensors, making them bulky, expensive and impractical. Li and his team are taking a different approach.

Instead of using hundreds of separate sensors, Li and his researchers are developing a method that allows a single sensor to capture the same information via a specially designed encoder. The encoder assigns a unique spatiotemporal signature to each incoming sound wave. A reconstruction algorithm then interprets and decodes the signals.

These advances have the potential to lower the size, cost and power consumption of imaging systems. The researchers believe the device could be used in telemedicine, remote diagnostics and real-time disease monitoring. Li’s lab will also collaborate with clinicians to explore how the miniaturized technology could help monitor cancer treatment and other conditions.

“Reducing the number of detection channels from hundreds to one could shrink these devices from bench-top systems into compact, energy-efficient wearables,” Li said in the release. “That opens the door to continuous health monitoring in daily life—not just in hospitals.”

Rice team develops complex wearables that can navigate users through Houston

hi, tech

A group of Rice researchers have tapped into the sense of touch to improve how wearable technology can communicate with its user.

Barclay Jumet, a mechanical engineering PhD student at Rice working in the labs of Daniel Preston and Marcia O’Malley, published the findings in the August issue of “Device.” The study outlines the group's new system of haptic accessories that rely heavily on fluidic control over electrical inputs to signal or simulate touch to a wearer. The research was supported by the National Science Foundation, the Rice University Academy of Fellows, and the Gates Millennium Scholars Program.

The accessories include a belt and textile sleeves, which deliver haptic cues like vibration, tapping and squeezing through pressure generated by a lightweight carbon dioxide tank attached to the belt. The sleeve contains up to six quarter-sized pouches that inflate with varying force and frequency, depending on what is being communicated to the wearer.

The team says the wearables have uses for those with visual and auditory impairments and offer a slimmed-down design compared to other bulky complex haptic wearables. The wearables are also washable and repairable, which gives them more everyday uses.

To test the system's usability, the team guided a user on a mile-long route through Houston, signaling haptic cues for forward, backward, left or right through the devices.

“In the future, this technology could be directly integrated with navigational systems, so that the very textiles making up one’s clothing can tell users which way to go without taxing their already overloaded visual and auditory senses—for instance by needing to consult a map or listen to a virtual assistant,” Jumet said in a release from Rice.

O’Malley, chair of the Department of Mechanical Engineering, said the system could also work in tandem with Cochlear implants and make lip-reading easier for users in noisy environments by directing users to sources of sound.

Jumet also sees uses outside of the medical space.

“Instead of a smart watch with simple vibrational cues, we can now envision a ‘smart shirt’ that gives the sensation of a stroking hand or a soft tap on the torso or arm,” he said in the release. “Movies, games and other forms of entertainment could now incorporate the sense of touch, and virtual reality can be more comfortable for longer periods of time.”

New Houston-born app OpenToBites connects users over meals in 16 cities

Friends and Food

A Houston-born social is connecting foodies and social butterflies for shared meals. OpenToBites launched on Android on June 18 and iOS on June 22, and is available to use for free in Houston and beyond.

Founded and operated by Houston developer Kelvin John, OpenToBites allows users to connect over meals in 16 cosmopolitan cities. That includes Austin and Houston in Texas, plus other American cities like Denver and New York, and even international destinations including Paris, Tokyo, and Sydney.

The app is built on a simple concept, and a press release emphasizes that it's for anyone who wants "friendly company."

“We built OpenToBites in response to several trends, including the rise of solo travel and the demand for social experiences that don’t feel like dating, networking, or large organized events,” said a spokesperson in the release. “We are not a dating app. We are offering shared food and conversation for people who want simple, in-person meal company in a public setting.”

When signing up, users provide their first name, an optional profile photo, and a short bio. They mark themselves as a traveler, a local, or both, and have the option to select their age range or opt out.

Once a profile is created, the user can search for existing meals or create a meal happening within the next 72 hours. To find an existing meal to join as a guest, they select the city, date, and apply filters for the number of seats, type of cuisine, and whether they want to share food with the table or order their own.

Since someone has to get the party started, users can also take the initiative to start a meal as a host. They'll choose the date, time, and restaurant — anything is on the menu, as long as they can link to the restaurant on Google Maps or its own website.

This divides users into "host" and "guest." Guests request to join a table, and a host can decide to accept the request or not. Guests aren't able to see the exact restaurant until their request is accepted, so hosts have a "helpful note" field to fill out with more information about the restaurant.

A similar app called Timeleft launched in Austin in 2024, acting as a friendship matchmaker for small groups of strangers who answer personality questions, meet at a restaurant for dinner, and decide if they wanted to stay in touch.

Though OpenToBites has a similar concept, it seems to work more like Couchsurfing, an app that connects travelers on their own terms. OpenToBites also emphasizes the immediate over the long-term — the meal itself is the social goal.

OpenToBites is available for free on the App Store and Play Store; the app plans to grow each current city's user base before adding new locations.

Houston mental health nonprofit expands platform statewide to connect more Texans with care

access granted

As mental health conversations evolve, the necessary pivot becomes how organizations across Texas navigate improved ways to help people access the care they need before their challenges become crises.

That’s why Mental Health America of Greater Houston recently announced that it is expanding its Care Connect platform statewide.

The expansion will address perhaps the most persistent barrier to behavioral healthcare—helping people find and navigate services that already exist.

Care Connect’s extended reach comes at a time when more than 3.5 million adults in the state live with some kind of mental health condition and scores of those in need continue to struggle with accessing care despite the growing awareness of mental health needs.

According to President and CEO Renae Vania Tomczak, Care Connect’s main goal was to remove as many obstacles as possible that Texans face when seeking mental health support.

“Care Connect was about a two-year planning process,” Tomczak says. “It really began with asking what challenges people in the Greater Houston Area were facing regarding mental health. It’s not just accessing care, but the difficulty in navigating the mental healthcare system.”

While provider shortages remain a challenge in some communities, Mental Health America of Greater Houston found that many individuals and families struggle simply to determine where to turn, how to identify the right provider and whether services are affordable.

“We wanted to make it easier for people who have questions, who may never have had a mental health challenge before, or they’re a caregiver for somebody who has a mental health issue,” Tomczak says. “We wanted to be the place that people can come to get their questions answered and be connected to care.”

Care Connect combines a vetted network of more than 1,000 providers and services across Texas with personalized navigation support.

Searches generate care results based on insurance coverage, language preferences, ZIP code and clinical specialties.

Additionally, one-on-one guidance and follow-up support are provided by bilingual resource specialists.

The platform also seeks to address affordability, one of the most significant barriers to mental healthcare access. Through participating providers, eligible individuals can receive six to eight counseling sessions at no cost.

“We have several providers who are willing to provide six to eight counseling sessions at no cost for people who do not have the means to pay for services themselves,” Tomczak says.

When provider matches are unavailable, the organization can connect individuals with master’s-level mental health professionals working under the supervision of licensed clinicians.

The statewide rollout builds on the platform’s early success in the Houston region, where it has helped thousands of individuals connect with mental health resources since launching last fall.

According to Tomczak, the decision to expand was driven in part by growing demand from outside the organization’s traditional service area.

“Last month we decided to take this program statewide,” she says. “It’s not just Houston that can use help in connecting to appropriate mental health services, but the whole state.”

The Care Connect program’s promotion through healthcare providers, community organizations and public-sector partners across Texas is now one of Mental Health America of Greater Houston’s top priorities.

Their goal is to create a stronger referral ecosystem that ultimately helps those who need access to mental health care more quickly.

To facilitate that, the organization has also added free mental health screenings to its website so that users will better identify any symptoms related to anxiety, depression and other conditions.

“Once they do that, then where do they go?” Tomczak says. “They’re not sure who to call and who can help them. At that point, we hope they’ll call us and talk to somebody live who can answer their questions and help them get started on the right path to improving their mental health.”

With eyes on the future, Tomczak believes public understanding of mental health has improved in recent years, particularly following the COVID-19 pandemic, which brought new attention to the effects of stress, isolation and uncertainty.

“The more we talk about it and have the opportunity to share that mental health conditions are traceable, the better,” she says.

According to Tomczak, long-term, Care Connect aims to reduce roadblocks that exist between recognizing the need for help and receiving it.

Ultimately, Care Connect hopes to create a robustly connected behavioral health system that gives Texans the ability to access mental health services swiftly and with confidence.

“No one should have to navigate mental health challenges alone,” Tomczak adds. “Care Connect is here to help connect people with resources, services and answers to ensure they get the care they need to take the next step toward better mental health.”
