Mark Sephton

Geological detective Mark Sephton has built his career looking for molecular clues of past life. Organic geochemistry, or the forensic science of organic molecules in rocks, is a passion that this Professor at the Imperial College London in the UK is taking all the way to Mars.

Mark has been recently selected as one of the few European scientists participating in NASA’s Mars 2020 science team, a mission launched to our neighbouring planet on July 30 2020. He will be involved in the selection of martian samples to be returned to Earth.
