Abstract

I am a 4th year PhD student at the Institute of Astronomy, University of Cambridge, supervised by Prof. Oliver Shorttle and Dr Paul B. Rimmer, and funded by STFC. I research planetary science and astrobiology.

I grew up in Nicosia, Cyprus. After high school, I moved to the UK where I studied Physical Natural Sciences (BA/MA) and Astrophysics (MSc) at Trinity College, University of Cambridge. I then took 2 years off before my PhD: partly working remotely (ML Lead in a startup; for more info see my LinkedIn), and partly travelling (wherever covid allowed; for more info see non-research or ask!)

Introduction

My doctoral research is focused on a central challenge in astrobiology: to find life, one must first be able to define lifelessness. I studied the planetary atmosphere, volcanism, and weathering of Venus to deconstruct the fundamental processes of an abiotic world. This work culminated in a framework for how to search for life, and its absence, beyond our solar system.

Supplementary: Non-research

I favour the micro-adventure: cycling day-trips around Cambridge, weekends away scrambling with friends, bouldering, waking early for a long walk toward a light-roast coffee and a pastry, inching closer to a solo gliding license when the skies permit.

Sometimes the itch gets the better of me and I go further. A stretch of solo travel. Bikepacking!! Currently planning a ~6 month trip post-PhD, leaving Cambridge and cycling east.
