My research centers on the nanoscale patterns that develop spontaneously when a solid surface is bombarded with a broad ion beam. These patterns include ordered arrays of nanodots and surface ripples with wavelengths as short as 10 nm. From a more mathematical standpoint, I study self-organization in systems driven far from equilibrium as well as solitons and shockwaves.

My research interests are in the field of algebraic number theory, and more specifically, arithmetic dynamics. The main focus of my research is studying how the absolute Galois group of a field acts on pre-images of a point under iterates of a rational function. This area has many nice applications to number theory and dynamics.

Postdoctoral Fellows

Mayla Boguslav / Postdoctoral Fellow - Kirby
Office: Weber 115

My research interests lie in the meta-science space and research development through the lens of natural language processing and mathematics. I am very interested in how researchers decide what questions to ask/research and how they form collaborations based on that and in general. My PhD research focused on extracting, revealing, and exploring the known unknowns or goals for scientific knowledge mentioned in the literature (ignorance statements). I created a knowledge-base of such statements that we termed an ignorance-base to help researchers better explore the state of our scientific knowledge and ignorance. I am continuing this work through the Data Science Research Institute. I am also interested in clinical natural language processing and I am working and learning about Veterinary health records. I am also teaching mathematics in biology and medicine (Math 455) in Fall 2023.
