I am passionate about researching and teaching math. I am interested in using technology both in my research and in the classroom. My work bridges ideas and techniques from number theory and combinatorics. My work often connects to other fields such as finite geometry, arithmetic geometry, or arithmetic statistics. I'm always happy to discuss these areas of math with students.

I am also dedicated to mentorship and diversity initiatives. My work in this area has focused on supporting minorities in STEM.

You can see more information about me at my website.
