About

Dr. Gregory Frazier is a pioneering planetary scientist whose work has fundamentally advanced our understanding of Mars’ geochemistry and habitability. His primary research focuses on the chemical and isotopic composition of Martian volatiles and atmospheric processes, with a major emphasis on in-situ planetary instrumentation. Dr. Frazier’s most significant contribution is his central role in the Sample Analysis at Mars (SAM) investigation aboard the Mars Science Laboratory (MSL) Curiosity rover. His landmark paper, "The Sample Analysis at Mars Investigation and Instrument Suite" (2012), which has garnered over 560 citations, details the design and scientific objectives of this suite of instruments. This work has been critical in enabling the direct measurement of organic compounds and isotopic ratios in Martian rocks and atmosphere, providing key evidence for past habitable environments. Through his instrumental expertise, Dr. Frazier has helped transform our view of Mars from a barren world to one with a complex geochemical history, leaving an indelible mark on the field of astrobiology and planetary exploration.
