**Intended Audience:** Mathematicians and high school students who think they are potential math geniuses.

We continue the interview with Moshe Cohen on line arrangements, but now at a graduate student level. To see the earlier interview with Moshe geared at a high school level, go to: Meet Mathematician Moshe Cohen.

In this interview, Moshe explains the theorem he proved in the paper, “Moduli spaces of ten-line arrangements with double and triple points,” by Meirav Amram, Moshe Cohen, Mina Teicher, and Fei Ye. The paper was supported in part by the Minerva Foundation of Germany through the Emmy Noether Institute and the Oswald Veblen Fund of the Institute of Advanced Study in Princeton. Moshe’s travel back to the United States to produce this video was supported by the European Research Council under the European Union’s Seventh Framework Programme, Grant FP7-ICT-318493-STREP.

First year graduate students (and high school students who think they are potential math geniuses) can investigate some of the words talked about during this interview, including:

fundamental group

complex projective plane

line arrangement

intersection lattice

moduli space
