Oakland Ave. Pasadena, CA 91101 (626) 584-5533 lkpaul@hss.caltech.edu Research Interests Dr. Paul is a Senior Research Fellow at Caltech. Her primary research focus is the role of the corpus callosum in emotions and social cognition. Dr. Paul is heading the Caltech Corpus Callosum Research Program and an inter-institutional research consortium on AgCC. The purpose of the Caltech AgCC Project is to characterize the neuroanatomy, effective connectivity, cortical organization, emotional responsiveness and social cognition in adults with Primary AgCC. These studies will in turn provide insight into the role of the corpus callosum in social-cognitive and emotional processing in people with various other diagnoses, including autism and schizophrenia. This AgCC Research Consortium involves collaboration of researchers from California Institute of Technology, Fuller Graduate School of Psychology/Travis Research Institute, University of California in San Francisco, and University of Southern California. Dr. Paul is also the founding president of the National Organization of Disorders of the Corpus Callosum (NODCC), a non-profit corporation that gathers and disseminates information on these conditions to individuals with corpus callosum disorders, their families and professionals.
