I am a gravitational wave astrophysicist that studies mid- to low-frequency gravitational waves. In the middle range, I work on the joint ESA/NASA mission LISA (Laser Interferometer Space Antenna), which is developing a space-based interferometer to search for sources such as black hole and ultra compact binaries. In this effort I contribute to data analysis and pipeline development. And in the low range I study pulsar timing, an effectively galactic-sized detector which uses pulsars across our galaxy to search for the signatures of gravitational waves coming from sources such as supermassive black hole binaries.
