Academic Interests and Areas of Expertise

- Number Theory
- Cryptography and Communications Security
- Mathematical Origami

Professional Background

My favorite flavor of mathematics is number theory. I began my number theory career studying Siegel modular forms and their related L-functions in my PhD thesis from Dartmouth College. More recent interests in number theory include cryptography and communications security. I am also interested in the mathematics underlying origami designs. I enjoy developing new courses to excite students about interesting and, sometimes unexpected, topics. I have designed mathematical courses in origami and cryptography, and first year seminars in historical cryptography and exploring fantasy novels. I am especially interested in developing materials to encourage active learning both in and out of the classroom and creating and using interactive software to allow students to explore mathematical results.
