About me

I am a Lecturer in Physics at Royal Holloway, University of London. I began my research career at the University of Southampton, working with Ian Jones and Reinhard Prix, where I completed my PhD in 2016 on Timing variations in neutron stars: models, inference and their implications for gravitational waves. Following this, I held a postdoc position at the Albert Einstein Institute, Hannover, before moving in 2018 to Monash University in Australia to work as an Assistant Lecturer with Paul Lasky. I then briefly joined the Institute for Cosmology and Gravitation (ICG) at the University of Portsmouth, working with Laura Nuttall as a Research Fellow before taking up my current post. My research interest is the relativistic astrophysics of neutron stars and black holes. I am a member of the LIGO Scientific Collaboration and co-chair the Collaboration's largest and most active observational science group, the Compact Binary Group.


  • 17/11/2023 New paper day: Work led by Ronaldas Macas Revisiting GW200129 with machine learning noise mitigation: it is (still) precessing

  • 07/Aug/2023 We hosted an In2Science student Pavan at RHUL. Pavan built the first iteration of the Duck Detector, a concept idea for a gravitational-wave outreach project (see image below). Overall the project was a success and afterwards Pavan said "He's relentless and passionate about physics and astronomy. He's handled the work experience like an absolute professional rightfully so. My experience couldn't have been any better, thanks to my mentor and his passion towards the subject and his willingness to outreach and teach the ways to young children. The best someone could expect." which I of course was very happy to hear.

  • 18/May/2023 I gave a colloqium on Glitch-robust gravitational wave astronomy at Los Alamos (virtually).

  • 15/May/2023 I co-organised and helped to run the 6th GWOSC Open Data Workshop. Below is a map of all the study hubs!
