Dr. Bridget Callaghan is an Assistant Professor in the Department of Psychology at the University of California, Los Angeles (UCLA). At UCLA, Dr. Callaghan directs the Brain & Body Lab in the Department of Psychology, and she also heads the Mental Disorders and Pain research theme at the Goodman Luskin Microbiome Center. She graduated from the University of New South Wales, Australia, with a bachelor’s degree in Psychology, and completed her master’s degree in Clinical Psychology and her doctorate in Psychology at the same institution. Her subsequent postdoctoral training in neuroimaging and child development was completed at Columbia University and New York State Psychiatric Institute, and was funded by a National Health and Medical Research Council postdoctoral training grant from Australia, Brain and Behavior Research Foundation Young Investigator grant, and then a career development award (K99) from the National Institutes of Mental Health. At UCLA, Dr. Callaghan is generously funded by the National Institutes of Mental Health, and the National Institutes of Aging. Together with her students, Dr. Callaghan examines how early life experiences get under the skin to influence mental and physical health. She takes a multigeneration approach in her research, and pays particular attention to the brain-gut- microbiome axis because of its strong links to health outcomes.
