I am exploring the effects of orbital eccentricity on gravitational waveforms of coalescing compact binary systems, in particular at the interface of analytical and numerical relativity. My project consists of improving the accuracy of existing analytical waveform models by comparing them to each other and to waveforms produced by numerical relativity simulations, which are currently the most accurate solution to the two-body problem in General Relativity. This topic is very relevant for LIGO, Virgo, and future space detectors, such as LISA.Publications

I received my A.B. in Astrophysics & Physics from Harvard University in May 2020. As an undergraduate, I worked on a variety of research projects, e.g. visualizing ionized hydrogen in galaxy simulations, comparing large-scale galaxy clustering in warm and cold dark matter simulations, and studying the detectability of higher-order harmonics in gravitational waves produced by binary black holes. For my senior thesis, I produced mock galaxy catalogues of f(R) modified gravity and General Relativity as a way to investigate the nature of gravity. In November 2020 I joined Prof. Buonanno’s department at the AEI as a Fulbright Researcher. In September 2021 I will pursue my PhD in Physics at Stanford University.
