I am an Assistant Professor in the Math Department of Boston College.

My main area of interest is algebraic geometry. I specialize in studying moduli spaces using logarithmic geometry in the sense of Kato-Fontaine-Illusie,

and its applications to Gromov-Witten theory and birational geometry.

My CV.
