Ralph Adolphs obtained his Ph.D. at Caltech in 1993, subsequently conducted postdoctoral work with Antonio Damasio in lesion patients, and has been on the faculty at Caltech since 2004. Ralph’s laboratory includes undergraduate students, graduate students, postdoctoral fellows and staff that all work on elucidating the neural underpinnings of social behavior. The lab studies several clinical populations, including neurosurgical patients, individuals with rare brain lesions, and people with autism. Extensive use is also made of the adjacent Caltech Brain Imaging Center, which Ralph directs, and there are close collaborations with other laboratories at Caltech in both the divisions of biology and the humanities and social sciences.
