SeqView
When analyzing Multi-Omics data, it is often useful to view the data in a genome browser. Many popular genome browsers exist for this purpose such as IGV, HiGlass, and the UCSC genome browser. However, if a researcher has a large number of Omics Datasets, it is often difficult to browse through these datasets for ad-hoc viewing in a genome browser. Developed as part of the Mahony lab at Penn State, SeqView solves this problem by wrapping popular genome browsers such as IGV and HiGlass around a search system for finding datasets based on metadata. This approach is modular and seamlessly integrates with genome browsers through their API.
Constructing Picard Curves with Complex Multiplication using the Chinese Remainder Theorem
We give a new algorithm for constructing Picard curves over a finite field with a given endomorphism ring. This has important applications in cryptography since curves of genus 3 allow one to work over smaller fields than the elliptic curve case. For a sextic CM-field $K$ containing the cube roots of unity, we define and compute certain class polynomials modulo small primes and then use the Chinese remainder theorem to construct the class polynomials over the rationals.

The twisting Sato-Tate group of the curve $y^2 = x^8 - 14x^2 + 1$
Published in Mathematische Zeitschrift, 2018
We determine the twisting Sato–Tate group of the genus 3 hyperelliptic curve $y^2 = x^8 - 14x^2 + 1$ and show that all possible subgroups of the twisting Sato–Tate group arise as the Sato–Tate group of an explicit twist of $y^2 = x^8 - 14x^2 + 1$ . Furthermore, we prove the generalized Sato–Tate conjecture for the Jacobians of all $\mathbb{Q}$-twists of the curve $y^2 = x^8 - 14x^2 + 1$
