Jessica Brezicha
Fellows Class of 2014



Rihana Bokari

Rihana Bokhari
Fellows Class of 2013
Doctoral student in Health and Kinesiology
Rihana will be studying ways to alleviate the negative effects of a reduced gravity environment on bone health using exercise regimens and hormone therapies.



Sarah Over

Sarah Over
Fellows Class of 2013
Doctoral student in Health Physics Sarah is interested in the effects of Galactic Cosmic Rays on the human body and in the radiation risks associated with long duration human spaceflight missions.



Anita Mantri

Anita Mantri
Fellows Class of 2012
M.D./Doctoral student in Biomedical Sciences
Anita will be studying the effects of the space environment on musculoskeletal health with the aim of eventually becoming a flight surgeon.



Jimmy Uhlemeyer


Jimmy Uhlemeyer
Fellows Class of 2012
Doctoral student in Health Physics
Jimmy is interested in understanding how radiation exposure promotes expansion of cell populations and will be using a chimeric animal model to make these in vivo observations.



Derek Seidel



Derek V. Seidel
Fellows Class of 2011
Doctoral student in Genetics
Currently, his interests include the alteration of gene expression, cell cycle control and immunological response within the intestinal tract as a result of factors encountered during prolonged space flight. Specifically, he is interested in the mechanisms of regulation by nutritional measures and how this might contribute to the maintenance of homeostasis within the colon.



John Seawright


John Seawright
Fellows Class of 2010
Doctoral student in Exercise Physiology
Area of Research: John’s interests revolve around the cardiovascular system. He is researching the role of reactive oxygen species in the aging vasculature and is elucidating the endothelial adaptations that accompany the cardiovascular dysfunction associated with exposure to ionizing radiation.



Kevin Shimkus


Kevin Shimkus
Fellows Class of 2009
Doctoral student in Exercise Physiology
Kevin is currently involved in the muscle aspects of two major research projects associated with spaceflight: a study looking at the musculoskeletal effects of multiple missions of weightlessness, and a second looking at the effects of lunar and Martian gravities on the musculoskeletal system.



Amanda R. Davis


Amanda R. Davis
Fellows Class of 2007
Doctoral student in Exercise Physiology
Area of Research: To study the presence of specific myokines that may be affected by microgravity and/or irradiation on systemic physiology.



Teak V. Lee


Teak V. Lee
Fellows Class of 2007
Doctoral student in Exercise Physiology
Area of Research: Investigate the role of dietary cholesterol and resistance exercise training as potential countermeasures to accelerated muscle loss.



R. Alex Redd



R. Alex Redd
Fellows Class of 2006
Doctoral student in Nuclear Engineering specializing in Health Physics & Space Radiation Biology
Area of Research: Uses GEANT4 to simulate HZE radiation transport in small sites and approximations of cells. He is interested in separating and comparing the effects of the primary particle to the secondary delta rays.
