It's hard to understate the impact Dr. William Cohn has had on cardiovascular health as a surgeon at the Texas Heart Institute or on health care innovation as the director of the Center for Device Innovation at the Texas Medical Center. However, his role as chief medical officer of BiVACOR might be his most significant contribution to health care yet.

The company's Total Artificial Heart is unlike any cardiovascular device that's existed, Cohn explains on the Houston Innovators Podcast. While most devices are used temporarily for patients awaiting a heart transplant, BiVACOR's TAH has the potential to be a permanent solution for the 200,000 patients who die of heart failure annually. Last year, only around 4,000 patients were able to receive heart transplants.

"Artificial hearts historically have had bladders that ejected and filled 144,000 times a day. They work great for temporary support, but no one is suggesting they are permanent devices," Cohn says on the show. Read more.

Promising Houston cancer research project wins $18M grant

fresh funding

The Biden-Harris administration is deploying $150 million as a part of its Cancer Moonshot initiative, and a research team led by Rice University is getting a slice of that pie.

AccessPath is a novel, affordable, slide-free pathology system that helps surgeons determine if they have completely removed tumors during surgery. Rebecca Richards-Kortum, a Rice bioengineering professor and director of the Rice360 Institute for Global Health Technologies, is the lead PI on the project that is receiving up to $18 million over five years from the Advanced Research Projects Agency for Health (ARPA-H).

“Because of its low cost, high speed, and automated analysis, we believe AccessPath can revolutionize real-time surgical guidance, greatly expanding the range of hospitals able to provide accurate intraoperative tumor margin assessment and improving outcomes for all cancer surgery patients,” Richards-Kortum says in a news release.

The project is focused on two types of cancer, breast and head and neck cancer, and Ashok Veeraraghavan, chair of Rice’s Department of Electrical and Computer Engineering and a professor of electrical and computer engineering and computer science, is a co-PI and Tomasz Tkaczyk, a professor of bioengineering and electrical and computer engineering at Rice, is also a collaborator on the project.

AccessPath is addressing the challenge surgeons face of identifying the margin where tumor tissue ends and health tissue begins when removing tumors. The project not only hopes to provide a more exact solution but do so in an affordable way.

“Precise margin assessment is key to the oncologic success of any cancer operation,” adds Dr. Ana Paula Refinetti, an associate professor in the Department of Breast Surgical Oncology at The University of Texas MD Anderson Cancer Center and one of the lead surgeons PIs on the project. “The development of a new low-cost technology that enables immediate margin assessment could transform the landscape of surgical oncology — particularly in low-resource settings, reducing the number of repeat interventions, lowering cancer care costs and improving patient outcomes.”

The project optimizing margin identification with a fast-acting, high-resolution microscope, effective fluorescent stains for dying tumor margins, and artificial intelligence algorithms.

AccessPath is a collaboration between Rice and MD Anderson Cancer Center, other awardees in the grant include the University of Texas Health School of Dentistry, Duke University, Carnegie Mellon University and 3rd Stone Design.

“AccessPath is exactly the kind of life-changing research and health care innovation we are proud to produce at Rice, where we’re committed to addressing and solving the world’s most pressing medical issues,” Ramamoorthy Ramesh, Rice’s executive vice president for research, says in the release. “Partnering with MD Anderson on this vital work underscores the importance of such ongoing collaborations with our neighbors in the world’s largest medical center. I am thrilled for Rebecca and her team; it’s teamwork that makes discoveries like these possible.”

Rice-led initiative looks to make cancer detection affordable, equitable

future of health care

A new initiative from two Houston organizations is hoping to develop affordable health care innovation for early cancer detection.

The Center for Innovation and Translation of POC Technologies for Equitable Cancer Care, or CITEC, will be managed through Rice360 Institute for Global Health Technologies, which is part of an ongoing international effort to prepare the future global health workforce.

Rice will be joined by Baylor College of Medicine, University of Texas MD Anderson Cancer Center, University of Sao Paulo, Barretos Cancer Hospital in Brazil, Mozambique Ministry of Health, and Universidade Eduardo Mondlane in Maputo, Mozambique.

“While early detection and treatment of cancer can improve survival, available tests for early cancer detection are too complex or too expensive for hospitals and clinics in medically underserved areas,” CITEC co-principal investigator Rebecca Richards-Kortum, a Rice bioengineering professor and director of Rice360, says in a news release.

The project is part of a five-year grant from the National Institutes of Health to launch a top-tier research center in the Texas Medical Center to develop point-of-care technologies that improve early cancer detection in low-resource in America and internationally that are effective and affordable. Rice’s leading collaboration group to help secure the grant includes engineers, oncologists and international global health partners from three continents. in low-resource settings in the United States and other countries.

CITEC will aim to target development of POC tests for oral, cervical and gastrointestinal cancers through the first-year grant from the National Institute of Biomedical Imaging and Bioengineering (NIBIB) of $1.3 million—up to $6.5 million over five years. CITEC is funded by a NIBIB grant.

Last month, NIBIB announced that CITEC will be one of six research centers that it will support, along with an additional center, through its Point of Care Technology Research Network (POCTRN).

Dr. Sharmila Anandasabapathy, vice president of global health at Baylor College of Medicine, and Tomasz Tkaczyk, bioengineering professor at Rice, are the other two cco-principals on the initiative.

“CITEC will identify needed technologies, accelerate their development, evaluate their performance and impact in diverse settings and train local users and technology developers to create and disseminate more equitable POC technologies,” Anandasabapathy says in the release.

Rice University students collaborate on COVID-19 solutions

game changers

An annual program with Rice University and its partners in Africa had to do things differently in light of the COVID-19 pandemic. Not only did operations have to shift to a virtual approach, but the projects themselves instead addressed the needs created by the disease.

Rice 360˚ Institute for Global Health, which collaborates with the Malawi University of Science and Technology (MUST) and the University of Malawi, The Polytechnic (Poly), continued their annual programming virtually over six weeks. The collaboration brings students together to solve global health issues, and this year's issue to address was overwhelmingly COVID-19.

"We had to give a lot of thought to whether we might have to cancel the program, and that was really heartbreaking to think about," says Rice 360˚ Director Rebecca Richards-Kortum, professor of bioengineering, in a news release. "Back in those days of late March and early April, I never really imagined how wonderful the virtual internship program could be."

Thirteen undergraduate interns and eight teaching assistants from Rice and Malawi, worked on six different projects, and three were presented in an online event on July 16. Here were the projects that were presented.

  • A disinfecting system that has the capability to sterilize multiple N95 masks at once. The system uses ultraviolet lights that can kill the coronavirus in around 30 minutes. Alternatively, the project included a smaller version that could be powered by solar energy. Yankholanga Pelewelo of MUST, Carolyn Gonawamba of Poly, and Andrew Abikhaled and Bhavya Gopinath of Rice developed the technology.
  • A walk-in decontamination unit that can decontaminate up to 3,000 people per day. The team of interns developed a prototype that consisted of PVC frame covered in plastic with nozzles to spray disinfectant. The project has already received interest from labs and hospitals for the device. Team members included Brenald Dzonzi of Poly, Mwayi Yellewa of MUST, and Kaitlyn Heintzelman, Krystal Cheung, and Sana Mohamed of Rice.
  • A redesigned intubation box that gives doctors better access to patients during the procedure. More than half of the 3,000 health care workers who have died from the coronavirus were doctors who focused on respiratory procedures, the team pointed out, and this daunting fact calls for redesigned tools. In total, the student innovators pitched three different designs that each included armholes in the sides, with a third hole on top to let a clinician or nurse assist with the procedure. The student team consisted of Chikumbutso Walani of Poly, Ruth Mtuwa of MUST, and Lauren Payne and Austin Hwang of Rice.

The other three projects included in the program but didn't present were designs for face shields, a hand sanitizer station and a contactless temperature monitor. All of the projects were led by teaching assistants Aubrey Chikunda and Chisomo Mukoka from MUST; Hannah Andersen, Nimisha Krishnaswamy, Alex Lammers and Ben Zaltsman of Rice; and Hope Chilunga and Francis Chilomo from Poly.

While pivoting the program to virtual comes with its challenges, Maria Oden — a professor of bioengineering, director of Rice's Oshman Engineering Design Kitchen and director of Rice 360˚ — recognizes the opportunities it provides as well.

"It would have been easy and understandable to cancel this internship, but that's not what happened, and look what the result was," Oden says in the release. "Over 90 people have tuned in to see the work of the interns. That's something we've never achieved with our in-person internships. We can learn from this experience."

Houston doctor aims to revolutionize hearing aid industry with tiny implant

small but mighty

“What is the future of hearing aids?” That’s the question that led to a potential revolution.

“The current hearing aid market and technology is old, and there are little incremental improvements, but really no significant, radical new ideas, and I like to challenge the status quo,” says Dr. Ron Moses, an ENT specialist and surgeon at Houston Methodist.

Moses is the creator of NanoEar, which he calls “the world’s smallest hearing aid.” NanoEar is an implantable device that combines the invisibility of a micro-sized tympanostomy tube with more power—and a superior hearing experience—than the best behind-the-ear hearing aid.

“You put the NanoEar inside of the eardrum in an in-office procedure that takes literally five minutes,” Moses says.

As Moses explains, because of how the human cochlea is formed, its nerves break down over time. It’s simply an inevitability that if we live long enough, we will need hearing aids.

“The question is, ‘Are we going to all be satisfied with what exists?’” he asks.

Moses says that currently, only about 20 percent of patients who need hearing aids have them. That’s because of the combination of the stigma, the expense, and the hassle and discomfort associated with the hearing aids currently available on the market. That leaves 80 percent untapped among a population of 466 million people with hearing impairment, and more to come as our population ages. In a nearly $7 billion global market, that additional 80 percent could mean big money.

Moses initially patented a version of the invention in 2000, but says that it took finding the right team to incorporate as NanoEar. That took place in 2016, when he joined forces with cofounders Michael Moore and Willem Vermaat, now the company’s president and CFO, respectively. Moore is a mechanical engineer, while Vermaat is a “financial guru;” both are repeat entrepreneurs in the biotech space.

Today, NanoEar has nine active patents. The company’s technical advisors include “the genius behind developing the brains in this device,” Chris Salthouse; NASA battery engineer Will West; Dutch physicist and audiologist Joris Dirckx; and Daniel Spitz, a third-generation master watchmaker and the original guitarist for the famed metal band Anthrax.

The NanoEar concept has done proof-of-concept testing on both cadavers at the University of Antwerp and on chinchillas, which are excellent models for human hearing, at Tulane University. As part of the TMC Innovation Institute program in 2017, the NanoEar team met with FDA advisors, who told them that they might be eligible for an expedited pathway to approval.

Thus far, NanoEar has raised about $900,000 to get its nine patents and perform its proof-of-concept experiments. The next step is to build the prototype, but completing it will take $2.75 million of seed funding.

Despite the potential for making global change, Moses has said it’s been challenging to raise funds for his innovation.

“We're hoping to find that group of people or person who may want to hear their children or grandchildren better. They may want to join with others and bring a team of investors to offset that risk, to move this forward, because we already have a world-class team ready to go,” he says.

To that end, NanoEar has partnered with Austin-based Capital Factory to help with their raise. “I have reached out to their entire network and am getting a lot of interest, a lot of interest,” says Moses. “But in the end, of course, we need the money.”

It will likely, quite literally, be a sound investment in the future of how we all hear the next generation.

Houston VC funding surged in Q1 2025 to highest level in years, report says

by the numbers

First-quarter funding for Houston-area startups just hit its highest level since 2022, according to the latest PitchBook-NVCA Venture Monitor. But fundraising in subsequent quarters might not be as robust thanks to ongoing economic turmoil, the report warns.

In the first quarter of 2025, Houston-area startups raised $544.2 million in venture capital from investors, PitchBook-NVCA data shows. That compares with $263.5 million in Q1 2024 and $344.5 million in Q1 2023. For the first quarter of 2022, local startups nabbed $745.5 million in venture capital.

The Houston-area total for first-quarter VC funding this year fell well short of the sum for the Austin area (more than $3.3 billion) and Dallas-Fort Worth ($696.8 million), according to PitchBook-NVCA data.

While first-quarter 2025 funding for Houston-area startups got a boost, the number of VC deals declined versus the first quarters of 2024, 2023 and 2022. The PitchBook-NVCA Monitor reported 37 local VC deals in this year’s first quarter, compared with 45 during the same period in 2024, 53 in 2023, and 57 in 2022.

The PitchBook-NVCA report indicates fundraising figures for the Houston area, the Austin area, Dallas-Fort Worth and other markets might shrink in upcoming quarters.

“Should the latest iteration of tariffs stand, we expect significant pressure on fundraising and dealmaking in the near term as investors sit on the sidelines and wait for signs of market stabilization,” the report says.

Due to new trade tariffs and policy shifts, the chances of an upcoming rebound in the VC market have likely faded, says Nizar Tarhuni, executive vice president of research and market intelligence at PitchBook.

“These impacts amplify economic uncertainty and could further disrupt the private markets by complicating investment decisions, supply chains, exit windows, and portfolio strategies,” Tarhuni says. “While this may eventually lead to new domestic investment and create opportunities, the overall environment is facing volatility, hesitation, and structural change.”
