Todd has been with KBR, the contractor for NASA’s Human Health and Performance Contract, for nineteen years. He started at JSC as a scientist developing mammalian cell biology payloads for the International Space Station, later monitoring the biodosimetry of radiation exposure in astronauts on ISS, then supporting program integration for the Human Research Program and program surveillance for health and medical issues in the Constellation Program. He has been with the NASA JSC Microbiology Laboratory for nine years and has a Bachelor of Science degree in Microbiology from Texas A & M University.
