MARK SHELHAMER, ScD
BS. Electrical Engineering, Drexel University MS. Electrical Engineering, Drexel University PhD. Biomedical Engineering, Massachusetts Institute of Technology Dr. Shelhamer started at Johns Hopkins as a postdoctoral fellow in 1990. At MIT, he worked on sensorimotor physiology and modeling, including the study of astronaut adaptation to space flight. He then came to Johns Hopkins where he continued the study of sensorimotor adaptation with an emphasis on the vestibular and oculomotor systems. He has applied nonlinear dynamical analysis to the control of eye movements, including investigations of the functional implications of fractal activity in physiological behavior. In parallel with these activities, he has had support from NASA to study sensorimotor adaptation to space flight, amassing a fair amount of parabolic flight (“weightless”) experience in the process. He also serves as an advisor to the commercial spaceflight industry on the research potential of suborbital space flight. Dr. Shelhamer is the author of Nonlinear Dynamics in Physiology: A State-Space Approach, has published over 70 scientific papers, and has had research support from NIH, NSF, NASA, NSBRI, and the Whitaker Foundation. From 2013 to 2016, he served as NASA’s Chief Scientist for human research at the Johnson Space Center. |

BILL QUEALE, MD
Assistant Professor at the Johns Hopkins School of Medicine Dr. Queale is a board-certified internal medicine physician specializing in primary care. His passion is helping his patients maintain high levels of functional capacity throughout their lifespan while simultaneously mitigating the risk of acute injuries and illnesses requiring hospital care. He has been in private practice for over 20 years providing primary care services to high performing individual of all ages. He is also the founder of Negentex Systems Medicine, an organization created to design, implement and scale a new systems-based primary care model. His goal is to help co-create a new technology-enabled, individualized, longitudinal model of care to improve multiscale system resilience and mitigate the risk of adverse medical events for high performing individuals on Earth and in space. |

IVAN L. PADILLA, PhD
Senior Research Associate at Case Western Reserve University Dr. Padilla is an astrophysicist working in bioastronautics, risk-informed decision making, and the development of Bayesian networks built on directed acyclic graphs. His work aims to establish a quantitative framework that yields mission-risk estimates from physiological and operational data, guiding countermeasures and research priorities for exploration missions. Other areas of interest include human performance in extreme environments, tools that support crew health and performance, and translating these methods to medicine on Earth. |
