Hello, my name is Adam Marcus and this was my page from when I was a Gibbs Assistant Professor in Applied Mathematics at Yale University. I received my B.A./M.A. in Mathematics from Washington University in St. Louis in 2003 and my Ph.D. in Algorithms, Combinatorics, and Optimization under the supervision of Prasad Tetali from Georgia Tech in 2008.

Teaching:

For Mokshay's Geometric Probability class, a writeup of my presentation on Grothendieck's Inequality (comments and corrections welcome).

Fall 2009: AMTH 110 Intro to Quantitative Reasoning.

Spring 2009: AMTH 950b Topics in Discrete Mathematics: The Probabilistic Method

For Gil's Combinatorics class, a Walkthrough of Szemerédi Regularity Lemma (comments and corrections welcome).

Fall 2008: AMTH 110 Intro to Quantitative Reasoning.

Research Interests:

When I am pretending to be a mathematician, my main research interests lie in various areas of combinatorics. In particular, I tend to like things with strange constraints (like restricted orderings and, more recently, dimensionality restrictions).

When I am pretending to be a computer scientist, my interests lie a number of areas that involve algorithms and computation in high-dimensional vector spaces. In particular, I have a growing interest in a number of topics in machine learning, computational geometry, and optimization.

When I am pretending to be a Frankenstein-like combination of the two, my interests lie in what we (Dan and I) have dubbed "Combinatorial Linear Algebra", a convergence of ideas from the theory of stable polynomials, convex geometry, geometric functional analysis, convex programming, and (of course) linear algebra and combinatorics.

Teaching Interests:

My primary interest here is in the curriculum for general education mathematics courses. There are many practical skills that mathematics can teach someone (problem solving, understanding of probability and statistics, etc) and the current paradigm does not address these.

People I work/worked/will work with:

Here at Yale, most of my effort goes to working on problems that share an interest with Daniel Spielman and his former Ph.D. student Nikhil Srivastava (now at Microsoft, Bangalore).

At Georgia Tech, most of my time was spent working with my advisor, Prasad Tetali.

Before Georgia Tech, I spent a year in Budapest working with Gábor Tardos at the Rényi Institute. While there, I took a minor detour to work with Martin Klazar at Charles University in Prague. I also spent Summer 2006 visiting the Theory Group at Microsoft Research to work with Laci Lovász and Fall 2006 visiting Tel Aviv University to work with Noga Alon.

As a side project, I had the pleasure of working on a problem known as the Hexagramma Mysticum (specifically, the combinatorial aspects of it) with Steve Sigur.

As another side project, I actively consult with 8coupons, a website that gives local businesses an affordable way to advertise special deals and coupons online.

My research at Yale was funded in part by the National Science Foundation under a Mathematical Sciences Postdoctoral Research Fellowship, Grant No. DMS-0902962.
