Rice University professor earns $550k NSF award for wearable imaging tech​

science supported

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.”

Houston Spaceport launches $12M expansion for leading space tech co.

to the moon

Houston will get one step closer to the moon, as the Houston Spaceport at Ellington Airport (EFD) has announced an expansion of the lease for Intuitive Machines, the Houston space tech leader dedicated to furthering lunar exploration.

On July 15, the City of Houston announced passage of Amendment 1, which would add three acres of commercial space for Intuitive Machines at the spaceport and a $12 million infrastructure expansion. Approved by the city council and Mayor John Whitmire, the expansion will include new production, testing and support facilities. The amendment extends the current lease for Intuitive Machines from 20 years to 25 years.

"I want to shout out to Intuitive Machines about everything they’re doing at the Houston Spaceport. It’s exciting to see them expand. We’re starting to reach a critical mass out there — more and more aerospace companies want to be at the Spaceport because that’s where innovation is happening,” said Fred Flinkinger, who represents District E on the Houston City Council. “It’s a great sign of momentum, and we’re proud to have them here in Houston."

Intuitive Machines was the first commercial tenant for the Houston Spaceport when it moved into the facility in August 2016. Founded by Stephen Altemus, Kam Ghaffarian, and Tim Crain in 2013, the company holds three contracts with the National Aeronautics and Space Administration (NASA) to deliver payloads to the lunar surface. In 2023, the company opened its doors in Houston with a 105,572-square-foot Lunar Production and Operations Center that contains research and development labs, clean rooms, mission control centers, and a spacecraft assembly floor.


Intuitive Machines landed Odysseus on the moon in February 2024, the first privately owned soft lunar landing ever and the first soft landing since 1972.

The Houston Spaceport is owned and operated by the City of Houston and Houston Airports, who have an eye of keeping the city a prime name in space exploration. As "Houston" was the first word spoken on the moon when Apollo 11 landed in 1969, lunar exploration in particular has a soft place in the heart of the metropolis formerly known as Space City.

“This agreement reinforces Houston’s leadership in space innovation,” said Jim Szczesniak, director of aviation for Houston Airports. “We’re building infrastructure and supporting the next era of lunar and deep space exploration, right here at Houston Spaceport. This partnership represents the forward-thinking development that fuels job creation and drives long-term economic growth.”
