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. He joined the Cornell MS&E faculty in 1999 following his Habilitation and became a Full Professor in 2005. 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 Hybrid Silica Technologies, Inc . and the recipient of multiple awards including the Carl Duisberg Memorial Award of the German Chemical Society.
