Uli Grasemann
Postdoctoral Alumni, Ph.D. Alumni, Research Scientist
Uli's research focuses on computational modeling of cognitive disorders, including schizophrenic story processing and damage and rehabilitation in the bilingual lexicon. He has also developed methods for evolving wavelets for image compression. Ralph Hoffman of Yale was a co-advisor of his dissertation.
