## Steven Simon

## Assistant Professor of Mathematics

## Biography

I have been at Bard since Fall 2016, first as a visiting and as of Fall 2018 a tenure-track assistant professor in the Mathematics program. Before that, I was a Visiting Lecturer at Wellesley College (Fall 2013-Spring 2016) and a Visiting Assistant Professor at the Cooper Union for the Advancement of Science and Art (Fall 2011-Spring 2013) in the Albert Nerken School of Engineering. In Summers 2013 and 2014, I was a Visiting Postdoctoral Researcher at the Hebrew University of Jerusalem under the supervision of Gil Kalai. I received my Ph.D. from the Courant Institute of Mathematical Sciences (New York University) in 2011 as a MacCracken Fellow under Sylvain Cappell and my B.A. in mathematics from Yale University in 2005 after switching from a major in Philosophy at the beginning of my junior year.

## Teaching

In Fall 2019, I am teaching **MATH 312 (Advanced Calculus) **and** MATH 105 (Time, Space, and Infinity: Mathematical Perspectives on Philosophical Paradoxes), **the later being a course I designed on Zeno's paradoxes and the mathematics (irrational numbers, infinite series, and cardinality) used in "resolving" them. All of my course materials are available on Moodle. My past and current teaching is listed below:

## Research

My research is centered on applications of algebraic and geometric topology, with special emphasis on their use in answering questions in as well as motivated by those from geometric combinatorics and discrete geometry. I am especially interested in mass equipartitions (fair division problems for continuous and discrete measures, generalizing the classical "Ham Sandwich" theorem), as well as generalizations of Tverberg's theorem from convex geometry.
