Welcome! I am a third-year PhD student in the Department of Statistics and Data Science at Cornell University. My advisors are Professors Martin Wells and Sumanta Basu. I also collaborate with the Division of General Internal Medicine at Weill Cornell Medical College in New York City, which is where I am currently based. For the summer of 2022, I am working on urban planning research with the NYC Department of Design and Construction through a Public Interest Technology fellowship from Cornell Tech.
My research is broadly in the analysis of temporal and spatial phenomena. I enjoy thinking about theory and methods for fitting models often used in applied mathematics, such as ordinary and partial differential equations, to time series data. I also work on statistical methods for identifying spatial patterns of evolution over time in demographic and epidemiological contexts. Other areas of statistics and math that I like studying include network science, numerical analysis, and optimal transport.
Previously, I studied statistics at Yale University as a master’s student and at Cornell as an undergraduate.

More about me
I am from Los Angeles, California and have also lived in France, where I attended middle and high school, and the United Kingdom. Outside of statistics, I enjoy classical piano, painting, photography, running, and exploring New York City. My favorite dataset is the New York Philharmonic Performance History Database.
I co-organize the math/statistics Directed Reading Program at Cornell, which pairs undergraduates with PhD students to work on semester-long reading projects on topics of mutual interest.
If I were a Springer-Verlag Graduate Text in Mathematics, I would be J.L. Doob's Measure Theory.
I am different from other books on measure theory in that I accept probability theory as an essential part of measure theory. This means that many examples are taken from probability; that probabilistic concepts such as independence, Markov processes, and conditional expectations are integrated into me rather than being relegated to an appendix; that more attention is paid to the role of algebras than is customary; and that the metric defining the distance between sets as the measure of their symmetric difference is exploited more than is customary.
