Dr Megan Brown

Research Associate

I'm a planetary scientist and atmospheric chemist, specialising in development of global climate models both for Earth and Mars. I've worked with several different climate models, the most recent of which is the UK Chemistry and Aerosol chemistry-climate model. General areas of interest and research include: hydrogen deposition, heterogeneous reactions, mechanism reduction analysis, ozone, and abiotic HCN chemistry.
