I am a first year Postdoctoral Fellow at CUNY. I was previously a student of Joe Silverman at Brown University. 

Broadly speaking, my research interests are in algebraic number theory and arithmetic geometry. I like thinking about problems that involve group theory, Galois theory, local and global fields, and elliptic curves. 

I also have a strong interest in higher education, and mathematical pedagogy on all levels.
