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.

16 June 2016: I talked to Shannon Hall about black hole spins, for Sky & Telescope
15 June 2016: I was interviewed by Popular Mechanics about the new gravitational wave detection :)
31 May 2016: Horizons Magazine has highlighted my Marie Curie Project, GW ASAP, in their "What’s next for gravitational waves?" article
31 May 2016: Today I'm giving a talk at McGill, in Montreal, Canada.
16 May 2016: I am in Toronto, Ottawa and Montreal for the next three weeks, giving colloquia and visiting colleagues. I'll also be giving a talk at my former High School: RDHS!
4 May 2016: What's your #SparkOfScience? I shared mine with Nautilus Magazine, which they then created this short animation for.
29 April 2016: Nautilus Magazine highlighted part of my "Gravity Wave Hunter" interview, where I speak about my experience as a physicist. This touches on unwanted advances from senior faculty colleagues, unconscious bias, and (my) white privilege.
26 April 2016: Today I gave a talk to some very gifted students at Ad Astra, and then participated in my first "Science Speed Dating" event at NeueHouse, put on by The Science & Entertainment Exchange. A recap of the event is here.
