Main Focus

I am interested in using Advanced LIGO and Advanced Virgo to observe compact binary coalescences and using these observations to make inferences about the underlying physics of the most compact objects seen in nature. I would like to work on developing and improving the software that is used to observe these sources. I would like to explore what science could be extracted both with single observations and with a large population of gravitational-wave signals. I am also interested in the potential for conducting "multi-messenger astronomy" where coincident information from gravitational wave and electromagnetic observations are used to better understand the sources being observed.

Curriculum Vitae

I am a post-doctoral research associate at the AEI-Potsdam. I did my PhD in Cardiff, UK under Stephen Fairhurst and B.S. Sathyaprakash, which was focused on searching for compact binary coalescences in data from initial LIGO and Virgo. I then did a 3-year postdoc at Syracuse under Duncan Brown and Peter Saulson before moving to Potsdam.
