I grew up in London, UK and did my undergraduate studies there at Imperial College. I then did my PhD at DESY Zeuthen in Germany, supervised by Anna Franckowiak. My PhD focused on multi-messenger astronomy, and I searched for sources of neutrinos using the IceCube (a neutrino observatory) and ZTF (an optical survey). I also worked on the IceCube public alert system. I then spent three years as a postdoc at Caltech working with Mansi M. Kasliwal, and searched for EM counterparts to gravitational waves as well as neutrinos. In addition to ZTF, I worked on WINTER, a new near-infrared telescope for which I jointly built the pipeline. I also developed tdescore, a powerful ML-based algorithm to discover Tidal Disruption Events (TDEs) in ZTF survey data. Since Fall 2024, I've been a Neil Gehrels Prize Postdoctoral Fellow at JSI. I'm still working on MMA with ZTF and WINTER. I've also been focused on using tdescore to discover new TDEs in real-time with ZTF and LSST.
