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.

Katie is an undergraduate Molecular & Cellular Biology major and Space Science & Engineering minor at Johns Hopkins University. Her research interests include the effects of microgravity on the vestibular system and human physiology in extreme environments. She hopes to one day work at the intersection of Emergency & Aerospace Medicine. Outside of the lab, she is an EMT with the Hopkins Emergency Response Organization, volunteer at the Johns Hopkins Hospital Adult Emergency Department, and patroller with the National Ski Patrol. She enjoys cooking, baking, skiing, and backpacking in her free time.

Arjun is a recent graduate of Johns Hopkins University. There, he earned a Bachelor’s of Science while majoring in Molecular and Cellular Biology along with Applied Mathematics and Statistics. He also minored in Space Science and Engineering. He was a member of the Human Spaceflight Lab during all 4 years of undergrad, where he worked on everything from the neurovestibular to behavioral aspects of human spaceflight. He has presented work at the American Society for Gravitational and Space Research conference and NASA HRP IWS. Arjun’s prime interest lies in understanding how to treat and prevent space-induced deficits while also applying these treatments to conditions on Earth.

Shrutina is an aspiring undergraduate researcher at Johns Hopkins University, where she is pursuing a B.S. in Physics with a minor in Visual Arts. Her academic pursuits within space medicine center around understanding the intricacies of human physiology under the challenging conditions of microgravity and isolation. Fascinated by human behavior in extreme environments, she is driven by the various implications space medicine has on terrestrial health. With aspirations to venture into the medical field, Shrutina aims to become a flight surgeon, contributing to the safety and well-being of astronauts in future space missions. In her free time, Shrutina enjoys photography, roller-skating, and catching the sunrises and sunsets on walks!

Imelda is an Anesthesia and Critical Care Medicine resident at the Johns Hopkins Hospital. Previously, she attended Northeastern University where she studied Behavioral Neuroscience and completed her MD through the University of Vermont. Imelda then served as an Undersea Medical Officer with the US Navy where she worked at the Navy Experimental Diving Unit. Here, she supported Navy Diving health and research efforts as the Deputy Medical Department Head and Institutional Review Board Chair. She is passionate about addressing the unique challenges of providing health care in austere environments such as Saturation Diving and long duration space travel. Imelda plans to pursue more work in Aerospace Medicine when she graduates residency. She enjoys diving, training for triathlons, and home renovation projects in her free time.

Noor is a Master’s student in International Health at the Johns Hopkins Bloomberg School of Public Health where she serves as the President of the Student Body and the Head of Surgery for the Surgery, Obstetrics, Trauma, and Anesthesia Society (SOTAS). She just graduated with a B.S. in Neuroscience from University of Michigan where she was the Research Lead for the Collaborative Lab for Advancing Work in Space (CLAWS) and the Michigan Space Consortium Grant Recipient for 2023 (Issued by NASA). CLAWS developed an AR interface that supports astronauts on lunar missions: including navigation, geological sampling, and communication with the mission control center – that got her team the title of a National Top 10 finalists for the NASA SUITS Challenge with perfect scores at the Johnson Space Center (Houston, Texas). She has particular interest for space medicine and how research from the ISS has pioneered innovation for medicine practices on Earth – with a particular focus on Augmented Reality.

Sania is an undergraduate Mechanical Engineering and Applied Mathematics major at Johns Hopkins University. Her primary interest lies in the development of testing devices and technology tailored to aerospace applications. She hopes to earn her master’s degree in aerospace engineering and become an astronaut in the future. She is currently interning at Los Alamos National Laboratory, working on space instrumentation and design. Outside of HSL, she enjoys weightlifting, practicing martial arts, cooking, and trying new food.

Alyssa is a Biostatistics PhD Candidate, Vivien Thomas Scholar, and Center of Excellence in Regulatory Science and Innovation Scholar at the Johns Hopkins Bloomberg School of Public Health. She is a member of the Spring 2018 Class of NASA Datanauts and has delivered invited talks, guest lectures, and discussions on data science at conferences and universities worldwide. Previously, Columbus has worked as an information security analyst, data scientist, and machine learning researcher, and her technical articles and tutorials have been published and featured by leading organizations, including Google, Microsoft, O’Reilly Media, the American Statistical Association, and the Association for Computing Machinery. Columbus holds a Bachelor of Science in Mathematics from the University of California, Irvine and a Master of Science in Applied and Computational Mathematics from the Johns Hopkins Whiting School of Engineering.

Delancy is an undergraduate student in her third year studying Electrical Engineering at Johns Hopkins University. Her work in the Human Spaceflight Lab includes VANTAN data analysis and Posture analysis for commercial astronauts. In her free time, Delancy enjoys figure skating, reading books, and traveling.
