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.

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.

CEO hunting

Houston-based space exploration company Axiom Space is searching for a new CEO.

Co-founder Mike Suffredini stepped down effective August 9 as CEO. He cites unidentified personal reasons for his transition from CEO to company advisor. Suffredini remains a board member of Axiom Space.

Co-founder Kam Ghaffarian, the company’s executive chairman, is serving as interim CEO until Axiom Space taps Suffredini’s permanent successor.

“We are grateful for Mike’s invaluable contributions to human space exploration and the remarkable growth of Axiom Space,” Ghaffarian says in a news release. “He will continue to offer his unique perspective and expertise as we advance our mission.”

Suffredini — who managed NASA’s International Space Station program from 2005 to 2015 — founded Axiom Space in 2016 with Ghaffarian. The company operates missions to the International Space Station, is building the world’s first commercial space station, and is developing commercial infrastructure for the space economy.

At one point, Suffredini also held the title of president. Axiom Space executive Matt Ondler was promoted to that job in 2023.

Suffredini led the company as it reached numerous milestones, such as:

Earlier this month, Axiom Space named NASA veteran Peggy Whitson, a former student and professor at Houston’s Rice University, as commander of their next global crew heading to the International Space Station aboard a private mission. Whitson and her three fellow crew members arrived in Houston on August 6 to train with Axiom Space, NASA, and SpaceX for Axiom Mission 4. The mission is tentatively scheduled for October.

Houston space tech unicorn names next mission leader, team

ready for takeoff

NASA veteran Peggy Whitson, a former student and professor at Houston’s Rice University, will command the global crew heading to the International Space Station aboard a private mission directed by Houston-based Axiom Space.

Whitson and her three fellow crew members arrived in Houston on August 6 to train with Axiom Space, NASA, and SpaceX for Axiom Mission 4. The mission is tentatively scheduled for October 2024.

The three astronauts joining Whitson will be:

  • Shubhanshu Shukla, the mission pilot, representing the Indian Space Research Organization
  • Sławosz Uznański, a mission specialist representing the European Space Agency and Poland
  • Tibor Kapu of Hungary, a mission specialist

Axiom Mission 4 will be Whitson’s second commercial human spaceflight mission with Axiom.

“With a culturally diverse crew, we are not only advancing scientific knowledge but also fostering international collaboration. Our previous missions set the stage,” Whitson says in a news release.

Axiom Mission 1 was the first private mission to the space station, Axiom Mission 2 launched the first Saudi woman into space, and

Axiom Mission 3 featured the first Turkish astronaut and first European Space Agency astronaut to fly on a commercial space mission.

With Axiom Mission 4, “we ascend even higher, bringing even more nations to low-Earth orbit and expanding humanity’s reach among the stars,” says Whitton.

From 1981 to 1985, Whitson conducted graduate work in biochemistry at Rice, where she earned a doctoral degree. She was a predoctoral and postdoctoral fellow.

Whitson’s vast experience includes:

  • Adjunct professor in biochemistry and genetics at the University of Texas Medical Branch in Galveston
  • Adjunct assistant professor in biochemistry and genetics at Rice
  • Research biochemist at NASA’s Johnson Space Center
  • Deputy division chief of medical sciences at Johnson Space Center.
  • Chief of station operations at NASA’s Astronaut Office
  • Chief of NASA’s Astronaut Corps
  • Crew member of three NASA space missions

Whitton and the three other astronauts still must gain approval for the Axiom mission from the five organizations that oversee the space station: NASA, the European Space Agency, Roscosmos (the Russian space agency), the Japan Aerospace Exploration Agency, and the Canadian Space Agency.

Axiom 4 “represents Axiom Space’s continued efforts to build opportunity for countries to research, innovate, test, and engage with people around the world while in low-Earth orbit,” says Michael Suffredini, CEO of Axiom Space. “This mission broadens horizons for nations with ambitious goals of advancing scientific, technological, and economic pursuits.”

This mission will emphasize scientific research, tech demonstrations, and space commercialization.

From Florida, the Axiom 4 crew will go to the International Space Station aboard a Falcon 9 rocket and Dragon spacecraft, both made by SpaceX. The crew is expected to spend up to 14 days at the space station.

3 Houston innovators to know this week

who's who

Editor's note: In this week's roundup of Houston innovators to know, I'm introducing you to three local innovators across industries recently making headlines in Houston across energy and space tech.

Samra Nawaz, CEO and co-founder of WellWorth

As much as she loves a good Excel spreadsheet, Samra Nawaz had just about had it with the convoluted — and not always completely accurate — process of building financial models within upstream oil and gas.

"Excel is generally a good tool to automate workflows and build really robust spreadsheets. I live in Excel — I have a spreadsheet for everything," Nawaz says on the Houston Innovators Podcast. "What Excel is not is a database."

Engineering teams work with massive amounts with data that's too big for Excel, she explains, so finance teams then have to work off of aggregated data to build their financial models. She was ranting about why there isn't a better process to her husband, Vinay Acharya, who suggested that they build it themselves. Read more.

“Prada’s technical expertise with raw materials, manufacturing techniques, and innovative design concepts will bring advanced technologies instrumental in ensuring not only the comfort of astronauts on the lunar surface, but also the much-needed human factors considerations absent from legacy spacesuits,” says Michael Suffredini, co-founder, president, and CEO of Axiom Space.

The spacesuit, called the Axiom Extravehicular Mobility Unit (AxEMU), is geared toward improving astronauts’ flexibility, boosting protection against harsh conditions, and supplying tools for exploration and scientific activities.

“Our decades of experimentation, cutting-edge technology, and design know-how – which started back in the ’90s with Luna Rossa challenging for the America’s Cup – will now be applied to the design of a spacesuit for the Artemis era. It is a true celebration of the power of human creativity and innovation to advance civilization,” says Lorenzo Bertelli, marketing director of the Prada brand.

NASA has enlisted Axiom and Charlotte, North Carolina-based Collins Aerospace to outfit astronauts with next-generation spacesuits. Axiom’s partners on this project are KBR and Sophic Synergistics, both based in Houston, along with Air-Lock, A-P-T Research, Arrow Science and Technology, David Clark Co., and Paragon Space Development.

Collins maintains a sizable presence at the Houston Spaceport.

In July, Axiom secured a NASA task order potentially worth $147 million to modify the Artemis III spacesuit for astronauts heading to the International Space Station. This follows a $228 million NASA task order awarded to Axiom in 2022 for development of the Artemis III spacesuit.

The task orders are part of Axiom’s $1.26 billion spacesuit contract with NASA. All told, NASA has earmarked as much as $3.5 billion for new spacesuits.
