Overview
I am a gravitational-wave astrophysicist, and I search for black holes and neutron stars using gravitational waves to unlock the secrets of how the fundamentals of the universe operate. This new way to look at the world around us was pioneered in 2015, with the LIGO-Virgo Collaboration's detection of the binary black hole merger GW150914.
I am a member of the LIGO Scientific Collaboration, and specialise in the astrophysical interpretation of gravitational-wave observations. My work includes charaterizing the detected black holes and neutron stars at the source of the signals, and planning for the future discoveries of transient gravitational-wave astronomy.

My research focus is in gravitational-wave astrophysics. I am especially interested in:
- Astronomy: Transient gravitational-wave observations. In particular with the LIGO (Laser Interferometer Gravitational-wave Observatory) and Virgo interferometer network and jointly with Electromagnetic or Neutrino counterparts.
- Experimental physics: Optimized experimental design of future detectors. Holistic modeling for gravitational-wave observatories.
- Astrophysics: Understanding gravitational sources with parameter estimation using Bayesian Methods. Inference of universal properties using multiple events.
