Brief Bio


I am a gravitational wave astrophysicist. I primarily work on the joint ESA/NASA mission LISA ("Laser Interferometer Space Antenna"), an upcoming space-based interferometer to search for gravitational wave sources such as black hole and ultra compact binaries. In this effort I contribute to data analysis and pipeline development.


I also study pulsar timing, which uses pulsars across our galaxy to search for the signatures of gravitational waves coming from sources such as supermassive black hole binaries. There I have mostly contributed to waveform modeling.


I am also interested in mission concept development for future space-based gravitational wave detectors beyond LISA. Especially methods in the "micro-Hertz" gravitational wave band, the portion of the gravitational wave spectrum between space-based interferometers like LISA and pulsar timing arrays.

Research Interests


LISA Gravitational Wave Research

Astrophysics: Gravitational Waves

I currently work on data analysis methods for the LISA (Laser Interferometer Space Antenna) mission.


Gravitational Waves and Pulsar Timing

Astrophysics: Gravitational Waves

I am a member of the NANOGrav collaboration (North American Nanohertz Observatory for Gravitational Waves), and study the effects of gravitational waves on pulsar timing experiments.
