I am an observational astrophysicist working on cosmic explosions, called supernovae, that characterise the death of a star. My current research focuses on the brightest supernovae explosions, usually referred to as "superluminous supernovae", and their use as high-redshift probes. I am also interested in the role of interaction and shocks on astronomical transients, as well as those reaching their maximum light and fading soon after in a few weeks, usually referred to as Fast transients or Fast, Blue, Optical transients (FBOTs). I am also working on the implementation of machine learning techniques for transient astronomy to classify and categorise different kinds of supernovae and extreme transients.

I have been awarded the 2021 MERAC Prize as the Best Early Career Researcher in Observational Astrophysics for the investigation of the extremes of stellar explosions, providing a pioneering contribution to their understanding and their role in astronomy and astrophysics.

My institutional roles are the following:

Deputy Director of Research at the School of Physics and Astronomy
Associate Dean of Equality, Diversity and Inclusivity, College of Physical Sciences & Engineering
Chair of the Equality, Diversity and Inclusivity (EDI) Committee at the School of Physics and Astronomy
Member of the Cardiff University Gender Equality Steering Group

My research focuses on extreme supernovae and the follow-up of electromagnetic counterparts of gravitation waves. I am the Principal Investigator (PI) and Survey director of the most recent extension of the Public ESO Spectroscopic Survey for Transient Objects plus (ePESSTO+, ~540 nights awarded by ESO), as well as one of the eight leaders of the original survey (PESSTO) and its first extension (ePESSTO). I was also science PI of the 'Superluminous supernova' and 'Fast transients' groups in the ePESSTO collaboration. I am one of the LSST:UK PIs and the LSST:UK Point of Contact (POC) for transient astronomy. as well as part of the LSST:UK Executive board.

I am the FORS2 instrument scientist in the ENGRAVE consortium, a European collaboration targeting electromagnetic counterparts of gravitational waves. I am a member of LSST Dark Energy Science Collaboration (DESC), LSST transient and variable stars (TVS) group, as well as of the Euclid Consortium leading the extreme supernova science (see here the Euclid Deep Field Strategy - https://bit.ly/2Gce3B3). I am also a member of the LIGO consortium.

I am currently the module organiser (MO) for the 4th year Physics Project (PX3350).
I have been the module organiser (MO) for the 3rd year (BSc, MPhys) and MSc course High-Energy Astrophysics (PX3245/PXT214) from 2019/2020 to 2023/2024.
