Joseph (also known as Joby) is a postdoctoral scholar in the planetary sciences section at JPL, where he works on the SHERLOC instrument going to Mars aboard the Mars 2020 rover. SHERLOC is an arm-mounted deep-ultraviolet Raman & fluorescence spectrometer, designed to detect the chemical signatures of past life or previous habitability on the red planet.
Joby is using his experience in optical spectroscopy to develop more advanced analytical methods for data collected by SHERLOC. This information will help us understand how to identify organic compounds on Mars, even at low concentrations, and determine whether or not they may have been produced by living organisms.
Joby also advocates for greater inclusivity and diversity for under-represented groups in STEM, particularly LGBT+ people, and is a trustee for the Pride in STEM charitable trust in the UK.
