Matthew Just

Blurred image of the arch used as background for stylistic purposes.

I am a graduate of Georgia Southern University (BS 2012, MS 2016). While my current research interests lie in elementary, analytic, and combinatorial number theory, I had a series of successful projects reviewing and writing mathematical models of infectious diseases. The computational skills I developed during this time I now utilize to develop and prove conjectures in number theory.

I am a former secondary mathematics teacher and am passionate about math education at all levels. For the past two years I taught the math content course for the middle grades math education majors at UGA. I also tutor students of all ages with a wide range of learning differences.

While I enjoy research at the highest level, guiding younger students into the joys of research is a priority for me. I serve as a mentor for the Directed Reading Program (DRP) and the Undergraduate Research Mentor for combinatorics and number theory. I have mentored 10+ students in many areas of pure math and math education, and my collaborative efforts have led to 1 accepted publication, and multiple publications in preparation.

I am thankful for my wife, Erin, who supports my tireless passion for thinking about math, and my kids, Filly and August, who remind me to take a break and enjoy life. I am an accomplished runner and guitarist, and play for the UGA Duplicate Bridge Club.

Research Interests:

My interests include problems in analytic and enumerative combinatorics, as well as analytic number theory. I seek to understand the subtle interplay between additive and multiplicative number theory, as highlighted by the connections between integers and integer partitions. The parallels between the combinatorial and analytic properties of power series, Dirichlet series, and modular forms remain a great mystery I strive to illuminate.
