Detailed Biography:

Linda Baum is an immunologist and pathologist who joined the UCLA Dept. of Pathology and Laboratory Medicine in 1989 as an Assistant Professor. Dr. Baum became a full Professor in 2002. Dr. Baum attended Stanford University, where she received a B.S. in Biology in 1979. She received her Ph.D., with Peter Cresswell in Immunology, and M.D. degrees from Duke University in 1986. Dr. Baum completed her residency in Clinical Pathology at UCLA in 1989, and is Board Certified in Clinical Pathology. She was a post-doctoral fellow in James Paulson's lab during her residency, where she investigated host effects on influenza virus tropism. As a faculty member at UCLA, Dr. Baum teaches in the Medical School and the Graduate School, and received the Excellence in Education Award. She is the Division Chief of Laboratory Medicine. Her current research focuses on the biochemistry of cell-cell interactions, especially those mediated by protein-saccharide interactions, in immune system and cancer models. She collaborates with UCLA investigators in the California Nanoscience Institute, the Center for Muscular Dystrophy, and the Dept. of Microbiology, Immunology and Molecular Genetics. She is a member of several training programs, including the Hematology/ Oncology, Tumor Cell Biology, and Tumor Immunology programs. She is also a member of the Medical Scientist Training Program Steering Committee, the Jonsson Comprehensive Cancer Center, and the Molecular Biology Institute.
