Episode 182: Michael Schmidt on what precision medicine means to human spaceflight

Today we have Dr. Michael A. Schmidt, the founder, CEO, and Chief Scientific Officer of Sovaris Aerospace, a company focused on assessments and solutions applied to humans in space and extreme environments on Earth. Michael is also a professor of aerospace medicine at the University of Central Florida College of Medicine, one of the few programs in the U.S. that offers a medical residency in aerospace medicine. Michael is known for his work pioneering the field of precision medicine. He uses molecular analytics, coupled with physiologic and behavioral assessments, to facilitate human performance and resilience on Earth as well as in the extreme environment of space. His work covers a spectrum from NASA, the NFL, the NBA, U.S. Olympic teams, Nike, SpaceX, Axiom Space, NASCAR, Special Operations, the Naval Submarine Medical Research Lab, the Mayo Clinic, and others. We had a long and fascinating conversation with Michael and decided to break the interview into two parts. This episode focuses on Michael’s background and the cognitive and physical challenges astronauts experience in spaceflight. We also dive into the many ways that precision medicine is facilitating human performance and resilience here on Earth. In part two of our conversation, Michael talks about his work with NASA and SpaceX on the challenges of civilian spaceflight and the future of Mars exploration, including the construction of permanent colonies on the Moon and Mars. You won’t want to miss that conversation. Show notes: [00:03:59] Dawn opens our interview mentioning that Michael grew up in Minnesota in a small farming community, asking if it’s true that he sometimes had to do chores in 20- to 30-degree weather. [00:06:50] Dawn asks if it is true that Michael fell in love with science at a young age, even building telescopes at the age of 11. [00:08:00] Dawn asks Michael what it was that led him to become so fascinated with space specifically. [00:08:58] Dawn asks if Michael ever thought about becoming an astronaut. [00:10:09] Ken asks if it is true that Michael was a big reader as a child. [00:11:21] Dawn asks Michael to talk about his childhood athletic interests. [00:11:55] Dawn asks how it was that a high school quarterback from a small town in Minnesota ended up at university in the United Kingdom. [00:13:38] Ken asks Michael what years he worked at NASA Ames Research Center. [00:14:51] Ken mentions that when Michael was at NASA Ames, he did work collecting molecular and physiologic assessments of humans using NASA’s 20-G centrifuge. Ken asks Michael to talk about the centrifuge and how he used it in his studies of hypergravity. [00:17:49] Ken comments on the fact that pieces of equipment like NASA’s 20-G centrifuge are a precious scientific resource, and when they cease functioning, unfortunately, they are unlikely to be replaced. [00:19:40] Ken and Michael discuss the fact that microgravity, despite being one of the most pressing effects on astronaut health, is the one of the least addressed problems in human spaceflight. [00:21:48] Ken explains that Michael is the founder, CEO and Chief Scientific Officer of a company called Sovaris Aerospace, which is focused on assessments and solutions applied to humans in space and extreme environments on Earth. Ken asks Michael where the idea came from to found this company. [00:24:35] Dawn explains that since the human genome was first sequenced, there has been an acceleration of genome-based technologies that have made it possible to consider a person’s genetic makeup, both in healthcare and optimizing performance. Dawn asks Michael to talk about the work he does applying genomics to human spaceflight. [00:28:52] Dawn asks about Michael’s direction of the molecular profiling and precision medicine efforts for the Golden State Warriors during their record-breaking 73-9 season [00:32:57] Dawn mentions that Michael published a review in the journal Metabolomics in 2013 that looked at the use of omics-based analyses and their potential to enhance astronaut safety and performance. Dawn goes on to say that omics allows us to identify differences in humans responsible for different responses to extreme conditions. Dawn asks Michael to talk about this review and what he learned in terms of the risk profile of individual astronauts and how personalized medicine could mitigate some of the risks. [00:42:01] Ken circles back to the heterogeneity of responses to exercise in space, a phenomenon that is seen on Earth as well. Ken notes that while large populations of astronauts don’t yet exist to be studied, large populations and their response to exercise can be studied on Earth, such as Marcas Bamman’s current NIH-funded multicenter exercise study with aging populations here at IHMC. Here Michael talks about his work creating “digital twins” of astronauts to model exposure to extreme environments on personalized digital models of astronauts. [00:46:04] Ken mentions that the difference between digital twin models in engineering and digital twins used in biomedicine is that engineered systems are nearly fully understood and can therefore be modeled with great accuracy and completeness, while there is much more unknown in biological systems. [00:48:15] Ken asks Michael, given all the confounds and environmental stressors in spaceflight, how confident can we be that omics analyses performed on Earth will provide useful insights about performance in space. [00:54:13] Dawn pivots to discuss Michael’s work as president of the Human Research Program for Civilian Space Flight, the purpose of which is to address the widespread needs that civilians will face as space travelers. [01:01:03] Ken shifts gears to ask Michael to talk about the specific cognitive and physical challenges that humans will face in long duration spaceflight, such as a flight to Mars. [01:10:05] Ken mentions that APOE4/4 positive patients see increased risk of cognitive decline from therapeutic radiation on Earth. Ken notes that while therapeutic radiation is different from the radiation experienced by astronauts, this still poses worrying prospects for APOE4/4 positive astronauts. [01:11:28] Ken and Michael discuss the importance of developing both biological and engineering countermeasures to hazardous exposure to astronauts in space.
