Director of Graduate Studies | Philosophy of Mind, Philosophy of Psychology, Cognitive Science

Professional Summary

Langland-Hassan's research spans the philosophy of mind, the philosophy of psychology, and cognitive science.  Of particular interest to him are cognitive theories of imagination and pretense, the nature of visual imagery and inner speech, and the relation of imagery and imagination to self-knowledge and introspection.  His work has explored the ways in which introspective and imaginative capacities can become disrupted in psychiatric disorders such as schizophrenia.  He was recently involved in an interdisciplinary study investigating the cognitive impact of inner speech deficits in people with aphasia.

Langland-Hassan arrived at UC in 2011 after spending two years as a Postdoctoral Researcher in the Philosophy-Neuroscience-Psychology program at Washington University in St. Louis.  He received his Ph.D. in philosophy in 2009 from The Graduate Center of the City University of New York, and his B.A. in philosophy from Columbia University in 1997.
