I am a Senior Postoc based at the IoA in Cambridge, UK. I work on various planet formation and debris disk topics, including the Herschel DEBRIS survey, the SCUBA-2 SONS survey, the SKARPS survey of planet-hosting stars, looking for warm dust with WISE and LBTI, using ALMA, and various theoretical aspects such as collisional evolution and dynamics. This work could be split into the (related) aspects of i) trying to understand debris disks as an intrinsically interesting outcome of planet formation processes, ii) using debris disks as a tool to learn about planetary systems in general, and iii) characterising warm debris disks and their evolution as a potential barrier to the future discovery of Earth-like planets around other stars. This page is an up to date astro-related CV.

Outreach

My PhD involved thinking about how planet formation depends on the star the planets form around, and what we might learn as more planets orbiting a range of different stars are discovered. I worked with Scott Kenyon of Smithsonian Astrophysical Observatory, part of the Harvard-Smithsonian Center for Astrophysics in Cambridge, MA in the USA. This link has a copy of my thesis as submitted (no corrections), though the body is just the first four papers listed here outlined a bit more in blog posts, links below.
