I'm a gravitational-wave astrophysicist
Gravitational waves (GWs) are ripples of space-time travelling at the speed of light originating from some of the most violent processes in the Universe, such as black hole mergers, which have just been detected.
As a gravitational-wave astrophysicist, I study low frequency GWs using Pulsar Timing Arrays (PTAs), a network of one or more radio telescopes used to regularly monitor a collection of millisecond pulsars. The pulsars beam radio waves to the Earth as they rotate, creating a lighthouse effect. These radio waves have very regular arrival times at the Earth, and deviations from the expected time of arrival could signal the presence of a GW.
The main sources of these GWs in the frequency region monitored by PTAs are supermassive black hole binary systems with masses in the range of millions to billion of solar masses.

I currently hold a Marie Curie Fellowship at the Max Planck Institute for Radio Astronomy. Publications here. Bio here.
