Research Topics

The mission of the Laboratory of Behavioral and Genomic Neuroscience is to contribute to a deeper understanding of the causes of alcoholism and comorbid neuropsychiatric conditions, notably stressor, trauma and anxiety disorders. Our goal is to elucidate the neural basis of these devastating diseases and help identify new directions for their prevention and effective treatment. To this end, we integrate behavioral measures with state-of-the-art methods for monitoring and manipulating neural functions in order to examine how environmental insults shape brain circuits to modify behavior.


Andrew Holmes was trained in the UK, where received his Bachelor’s (Hons) degree in Psychology and his Doctorate in Behavioral Pharmacology. He received postdoctoral training in behavioral neuroscience and behavioral genetics from Dr. Jacki Crawley at the NIMH. He is currently Chief of the Laboratory of Behavioral and Genomic Neuroscience, where he studies brain regulation of emotion and cognition.
