I do math at Muhlenberg!

I am an associate professor in the department of mathematics and computer science, Muhlenberg College. I received Ph.D. in 2003 from Johns Hopkins University, specializing in number theory. After teaching at Hendrix College for three years, I came to Muhlenberg College in 2007.

I teach a variety of math courses at Muhlenberg, ranging from introductory-level statistics and calculus to elective math courses such as number theory.

My research interests lie in number theory and I currently study topics related to distribution of prime numbers in the context of function fields. I enjoy working on cool math problems with undergraduates.

CV Schedule 2015 Fall

CURM (2015-2016) new

Jointly with Dr. Will Gryc, I am awarded a minigrant from the Center for Undergraduate Research in Mathematics, or, CURM for the academic year of 2015-2016. This grant will support two undergraduate research teams at Muhlenberg, one of which will be supervised by myself. My team consists of two bright and talented Muhlenberg students, Emily Nguyen ('16) and Brandon Tauber ('16).

Emily Nguyen is a senior mathematics and English major at Muhlenberg College. In her free time, she enjoys reading (and re-reading) books and doing CrossFit. Her favorite math classes at Muhlenberg would probably be Transition to Abstract Mathematics and Abstract Algebra. With the help of the CURM, she will be studying Zaremba’s conjecture on finite continued fractions with restricted partial quotients.

Brandon Tauber is a senior at Muhlenberg College, majoring in mathematics and minoring in computer science. After graduating he plans to attend graduate school for applied mathematics. He is a captain on the track and field team, and enjoys playing games and making art.
