A brief overview

My research interests focus on various problems within number theory and ergodic theory. My work frequently features asymptotic analysis, continued fractions, and exponential sums. My advisors were Florin Boca and Kevin Ford.

I have done several studies into continued fractions, investigating how sometimes small (and sometimes big) changes in the usual Regular Continued Fractions alter the various properties one expects a continued fraction expansion to have. Valentina Masarotto's Master Thesis is a useful and well-written introduction to this topic, and Alexey Ustinov has written several great papers in this area.

One of the biggest projects I have worked on has been a long-running study of continued fractions in higher dimensions, and their connections to hyperbolic spaces. This project has been undertaken with Anton Lukyanenko.

My high school mathematics teacher, Dr. John Gorman, helped develop my love of normal numbers, which I have continued to study to this day. Enthusiasts of this topic may find Bill Mance's work on normal numbers quite intriguing.
