Charles I. Delman

INTRODUCTION

Education & Training

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.

Community

I have given many years of leadership service to the University Professionals of Illinois, Local 4100, serving as President of the EIU Chapter from 2003 to 2009 and currently serving as chair of the Trustees and Audit Committee and delegate to the conventions of the Illinois and American Federations of Teachers.  I have also served for many years as Secretary of the Mideastern Illinois Labor Council.  I am proud to serve and represent the working people who make our society work!

I am an avid ecological landscape gardener and a member of the Grand Prairie Friends and the Grand Prairie Butterfly Club.

Research & Creative Interests

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.
