Curriculum Vitae Research Teaching Meetings Travel

Announcement: Spring 2015 AGNES conference will take place at Boston College from Friday, March 20 to Sunday, March 22.
The conference will be preceded by a mini-school for graduate students (10am-3pm on Friday, March 20).


I am an algebraic geometer. My research is partially supported by the NSF grant DMS-1259226 and Alfred P. Sloan Research Fellowship.

Meetings organized


I have taught a variety of undergraduate and graduate courses at Boston College (2012-present) and Columbia University (2008-2012).
I also supervise undergraduate research projects and reading courses at BC.
