I am delighted to join Arcascope as a data scientist and primary cloud engineer.
Before my position as a full-stack engineer at Arcascope, I was an assistant professor in the mathematics department at the University of Michigan. In Summer 2020, I started transitioning from academia to industry with an internship as a software engineer at Enel X North America. There, I worked with a team developing a solar+storage modeling app in R using the Shiny library.
I'm fascinated by UNIX-like operating systems and the history of UNIX. Currently I run Debian Linux and FreeBSD on my personal machines, and I have 8+ years experience using Linux for my primary OS. At work, I develop on macOS.
Sleep classification CNN
Using a convolutional neural network and short-term Fourier transforms (spectrograms) of accelerometer data, we can distinguish awake from asleep at 85-90% TPR with 60% FPR.

Unsupervised clustering of houses for sale
My partner and I are moving to Eau Claire, WI. To better understand the housing market there, I use k-means and OPTICS to segment for-sale house listings I scraped from Trulia.com.
The clustering was based on density of nearby venues, and also categories of nearby venues like coffee shops and parks/playgrounds, fetched from Foursquare's REST API.
My research in pure mathematics is in the intersection of algebraic geometry, commutative algebra, and harmonic analysis.
Accepted for publication in Pure and Applied Mathematics Quarterly.
Based on PhD Thesis.
Harnessing the powerful theory of Berkovich spaces, I prove a collection of theorems about singular algebraic varieties over positive characteristic fields. Reflecting deep connections between Berkovich spaces and Fourier transforms, I convert difficult bounds on singularities (derivative condition) to linear inequalities on transforms (algebraic condition).

By giving new, explicit formulae for the Frobenius action on local cohomology of certain kinds of projective varieties, I extend theorems of B. Bhatt and A. Singh relating singularities of these varieties to their cohomological structure. The key idea is to apply the local cohomology functors to graded free resolutions of the varieties' ideals.
Joint with Daniel Hernández, Karl Schwede, and Emily E. Witt.
We study new families of varieties where the log canonical and F-pure thresholds do not coincide; these are two numerical measures of singularities that have deep, mysterious connections. We also study a volume called the F-signature whose derivatives I related to other volumetric invariants of singularities as an undergraduate, working with Karl.
