My research area is combinatorial optimization, specifically optimization algorithms and modeling, and my advisor is Prof. Alan Goldman.  Currently my research has taken a more theoretical turn, and I am investigating problems in stable matching.  I've just posted two short papers on stable matching, with hopefully more to come (geologically) soon.  In the mean time, please feel free to also look around my earlier research endeavors.

Papers and Projects:
On the Computation of Stable Many to Many Matchings:  Written as a course project for 550:750 this short paper's key result is an enumeration algorithm for the set of all stable many to many matchings, using the "break marriage" concept of McVitie and Wilson. This algorithm is similar to the algorithm of Martinez et. al., but much better exposited.  (pdf)

Fair Matchings with an Application to Chess:  Another course project, this time for 550:457.  This is another paper on matchings, this time a modeling paper investigating how to find a minimum bias assignment of partners from opposing teams in a chess match using the stable matching polytope.  As usual, the most interesting stuff is in the 'future directions' part of the paper. (pdf) [Note:  Because the original game is constant sum, one could considerably simplify the problem presented in the introduction by replacing the simultaneous solution of LPs with the solution of a single min max problem.   This  fact was pointed out to me by Dr. Alan Goldman, and will hopefully be incorporated into the above shortly.]


Talks Given
:

Inequalities in Stochastic Linear Programming (powerpoint(this presentation contains a generalization of a theorem proven by Madansky, which I hope to write up soon)

Earlier/Ongoing Research:
Examining eBay Auctions to Determine Optimal Pricing:
(Joint with Eric Harley)  This work is just beginning, but attempts to examine historical eBay auction data to determine the optimal pricing for sellers, in particular for specialty markets.  Potential applications (outside of eBay itself) include small markets for commodities.
