I study molecules in space across the spectrum of molecular sources: from interstellar clouds, the birth places of stars, through to protoplanetary disks and planetary atmospheres, and even on to circumstellar envelopes around dying stars. Molecules have huge prebiotic significance since they are the elementary building blocks of planetary systems. I am interested in fundamental astrochemical processes, i.e., how molecules are formed and destroyed in different environments, and how they can be used to probe the physical conditions in the diverse range of extreme environments in which they survive.
