I am a PhD Candidate in the Department of Astronomy & Astrophysics at the University of Toronto in Canada. I'm interested in the major questions in cosmology: what are dark energy and dark matter? How can the large-scale structure we observe today tell us about the past and future of the universe?

My Research at a Glance

I focus on studying the large-scale network of matter in the universe called the Cosmic Web. I'm interested in the information that the complex extended structures within this "web," such as filaments and superclusters, hold about the history of our universe. Ultimately, I want to use filamentary structure to search for signs of beyond-the-standard-model physics and cosmology. By working at the intersection of simulations and observations, I am optimizing the information we can glean from existing data and preparing for future sky surveys.

Below are the four main projects I am currently working on in my thesis.
