The Wiesner Group
Ulrich Wiesner

Ulrich Wiesner studied Chemistry in Mainz, Germany, and Irvine, California. He gained his Ph.D. in 1991 with work at the Max-Planck-Institute for Polymer Research (MPI-P), Mainz, and was a postdoctoral fellow at the E.S.P.C.I. in Paris, France until 1993. After his Habilitation with work at the MPI-P in Mainz in 1998, he joined the Cornell MS&E faculty in 1999 as a tenured associate professor. He became full professor in 2005 and since 2008 is the Spencer T. Olin Professor of Engineering. He works at the interface between polymer science and solid-state chemistry/physics with the goal of generating novel hierarchical and multifunctional hybrid materials.   He is the co-founder of Elucida Oncology, Inc., working on translating theranostic optical nanoparticles into the clinic, and Terapore Technologies, Inc., with the goal to bring block copolymer self-assembly based ultrafiltration membranes to the market. He is the recipient of multiple awards including the Carl Duisberg Memorial Award of the German Chemical Society and the Arthur K. Doolittle Award of the American Chemical Society.
