I received my bachelor's degree in Mathematics from Harvard University and my Ph.D. in Mathematics from CornellUniversity, where my advisor was Allen Hatcher.  I also received a Master of Arts in Teaching, with specialty in Mathematics, from Tufts University.


I am interested in topology, geometry, dynamics, and applications of mathematics to economics and social choice.  

My primary area of specialization is low-dimensional topology, with a focus on knots, laminations, and foliations in 3-manifods.  I have also worked in classical geometry and billiard dynamics, both in conjunction with my EIU colleague Gregory Galperin.  The application of mathematics to economics and social choice is a recent research interest through which I hope to contribute to the solution of some of society's current pressing problems.
