Dr. Costes is a nuclear engineer, committed to bring quantitative approaches and modeling into the biological world. He spent four years at the National Cancer Institute quantifying the spatial and temporal properties of proteins using fluorescent 3D microscopy. As a principal investigator for 12 years at the Lawrence Berkeley National Laboratory, he dedicated his research to quantifying and modeling the impact of space radiation on humans and mice. Joining NASA Ames in 2016, he founded the Radiation Biophysics Laboratory, the AI/ML initiative for Space Biology and became the project manager for GeneLab and ALSDA. He is now the branch chief for the Space Biosciences Research Branch. Dr. Costes was awarded a M.S. in Nuclear Engineering from Texas A&M in 1994 and a Ph.D. in Nuclear Engineering from the University of California, Berkeley in 1999.
