## Philip Engel518 Science Center Harvard University |

Update: I am assistant professor at University of Georgia! I was previously at Harvard as an NSF postdoc, and did my PhD with Robert Friedman at Columbia. I am currently interested in two areas: Degenerations of K3 surfaces and anticanonical pairs, partly motivated by mirror symmetry, and tilings of Riemann surfaces and Hurwitz theory. I love talking about math and meeting new people, so please drop by my office if you feel like chatting. My email address is philip dot engel at uga dot edu. Thanks for visiting!

These days I am thinking about how to construct proper families over toroidal compactifications of the moduli spaces of K3 surfaces, and also about tilings. Papers:
