معرفی
Kerry Ressler is a Professor of Psychiatry at Harvard Medical School and serves as Chief Scientific Officer at McLean Hospital. His research focuses on elucidating the neural and molecular mechanisms underlying fear-based psychiatric disorders, particularly post-traumatic stress disorder (PTSD), phobic disorders, and panic disorders. He leads the Ressler Lab, which integrates translational approaches spanning animal models of fear learning with human genetic and clinical studies to identify novel therapeutic targets.
Dr. Ressler's research centers on molecular, genetic, epigenetic, and neural circuit mechanisms of fear memory formation and modulation. His lab employs mouse models of fear acquisition, consolidation, and extinction using optogenetics, DREADDs, cell-type-specific transcriptional profiling, and DNA methylation analyses to investigate amygdala-dependent circuits. Human studies focus on identifying genetic traits and neural processes contributing to fear-based disorders, with emphasis on biomarkers like PACAP, cortisol, and inflammatory markers. This work aims to translate mechanistic insights into targeted treatments for trauma-related illnesses.
Analysis of Dr. Ressler's recent publications reveals dominant themes in PTSD neurobiology, including sex-specific responses to trauma, neural circuit dynamics using advanced neuroimaging (fMRI, DTI), and genetic/epigenetic mechanisms. His work frequently involves large-scale collaborations (ENIGMA-PGC, AURORA study) examining biomarkers, white matter integrity, and precision psychiatry frameworks. Key subfields include fear extinction mechanisms, childhood adversity impacts, and inflammatory pathways in trauma responses.
Dr. Ressler directs the Ressler Lab at McLean Hospital's Oaks Building, utilizing a multidisciplinary approach that combines molecular genetics, viral-vector manipulations, and human clinical research. The lab is embedded within Harvard Medical School's neuroscience ecosystem and contributes to major initiatives including the ENIGMA-PGC PTSD consortium and AURORA observational cohort study, focusing on translating basic science discoveries into clinical applications for trauma survivors.
