Research Interests
My research involves the interplay of combinatorics, geometry, number theory, and harmonic analysis. I am largely interested in problems that say in one form or another that a sufficiently large set has sufficiently nice additive or geometric structure.
I study problems such as the finite field distance problem, finite point configurations, and sum-product phenomena. I am also interested in certain aspects of algebraic coding theory such as Steiner and Kirkman systems.
Books
"The Finite Field Distance Problem," was published in the Carus Mathematical Monographs in 2021 though the AMS Book Program. This book explores the vast literature concerning the so-called Erdös-Falconer Distance Problem in vector spaces over finite fields along with many generalizations of the problem and some related problems. Samples and more are available here.
