Biography

I am a postdoctoral associate at the Center for Interdisciplinary Exploration and Research in Astrophysics (CIERA) at Northwestern University. I have a Ph.D. in physics from the University of Minnesota, focusing on gravitational waves. I am broadly interested in gravitational-wave physics and data analysis methods for extracting astrophysical and cosmological information from them. I am a member of the LIGO scientific collaboration and the LISA consortium.

Since my research mostly focuses on the analysis of data, I am also interested in statistical methods and their applications to astrophysical problems.

Recent Posts

Gravitational-waves, anisotropies and the large scale structure of the Universe

This blog post is about some recent papers which I led or was a coauthor on, to use gravitational-waves as a probe to measure anisotropies in the universe. The fundamental idea of cosmology is that we can apply the laws of physics - broadly speaking the general theory of relativity - to the entire universe as a whole.
