Dr. Halgren joined the UCSD Department of Radiology in 2005. He co-directs the Multimodal Imaging Laboratory with his longtime collaborator, Dr. Anders Dale, helping to facilitate research integrating hemodynamic, electromagnetic, and structural imaging. His own research projects combine functional magnetic resonance imaging (MRI), magnetoencephalography (MEG), and electroencephalography (EEG), within the context of structural MRI, for high-resolution spatiotemporal mapping of brain activity during cognition. He validates these measures using intracranial recordings from microelectrode arrays in patients with epilepsy.

After completing his undergraduate work at UCSD, Dr. Halgren received his PhD in Neurosciences from UCLA in 1976, studying memory using single-unit recordings and electrical stimulation in the human medial temporal lobe. Eventually he joined the UCLA faculty, and served as Director of Neuropsychology at the California Comprehensive Epilepsy Program. He moved to France where he was an INSERM Research Director, then back to the Department of Radiology at the University of Utah, and finally to Harvard Medical School, where he founded the MEG lab.

In his research, Dr. Halgren attempts to identify, locate, and characterize the neurocognitive stages used to encode and interpret events. Of particular interest are middle latency focal processes that encode faces and words, and later distributed processes that organize attention, or integrate semantic stimuli with the ongoing cognitive context: Where are they generated? By which synapses? What is their role in information processing? The overall goal is to understand fundamental integrative cognitive processes at the synaptic and system levels.

Dr. Halgren serves on the Editorial Board of the journal Human Brain Mapping and is the Chair of the International Advisory Board for Biomagnetism.
