I am a Lecturer in Astrobiology in the School of Natural Sciences at Birkbeck, University of London, and a Research Associate in Earth Sciences at University College London (UCL) as part of the joint Birkbeck-UCL Centre for Planetary Sciences. I am the Progamme Director for Birkbeck's flagship MSc in Astrobiology as well as a Board Member of of the CPS and the Astrobiology Society of Britain (ASB).

I supervise several BSc., MSc., and PhD projects in astrobiology and planetary science at Birkbeck and UCL every year. Prospective PhD students and postdoctoral fellows should check this page for current openings in my group and other advertised positions.

Before joining Birkbeck/CPS, I was a Postdoctoral Fellow in Astronomy in the Department of Physics and Astronomy at University of California, Irvine (2018-2021), and a NASA Postdoctoral Program Fellow at NASA Ames Research Center in Mountain View, California within NASA's Nexus for Exoplanet System Science (NExSS) (2016-2018).
