Dr. Aizenstein is an expert on the cognitive and affective neuroscience of aging and geriatric brain disorders. He is trained as a geriatric psychiatrist and also a computer scientist. His research program is recognized for expertise in MRI analyses methods, as well as their use for clinical research in aging.
Dr. Aizenstein’s research group has developed semi-automated methods of morphometric and functional MRI analyses. He uses structural and functional neuroimaging to identify networks of brain regions associated with affective and cognitive processing, and how these change over time with and without intervention.
Dr. Aizenstein has experience with fMRI studies in a variety of psychiatric disorders involving mood and cognitive disorders. He will contribute his expertise in brain imaging, the analysis of brain images, and geriatric psychiatry. He has extensively worked with the other PIs and Co-Is through several NIH funded grants and publications. He is a skilled and valued mentor; he received the 2009 Departmental mentorship award. He has collaborated and mentored many investigators, including K awardees, post-doctoral students and graduate students.
