Elmar Winkelnkemper

From Wikipedia, the free encyclopedia

Horst Elmar Winkelnkemper is a tenured associate professor of mathematics at the University of Maryland, College Park. A graduate from Princeton University and the University of Mexico, Winkelnkemper is was born in Cologne, Germany but was raised in Mexico. Winkelnkemper joined the Maryland faculty in the 70's and currently teaches mathematics to undergraduate honors and graduate students. Since joining Elmar has published many papers. His field of expertise is in topology, manifolds, and string theory. In addition, his major contribution has been to open book decomposition and expanding on the work of Edward Witten in string theory.
