Elizabeth Bartlett, PhD

Dr. Elizabeth (Betsy) Bartlett is a biomedical engineer, Assistant Professor in the Department of Psychiatry at Columbia University, and a faculty member of the Brain Imaging Lab in the Molecular Imaging and Neuropathology Area at the New York State Psychiatric Institute. Dr. Bartlett’s work focuses on development and use of state-of-the-art qualification techniques for in vivo human positron emission tomography (PET) brain imaging. These less-invasive and non-invasive techniques simply PET acquisition, minimize patient burden, and reduce cost, thereby reducing the barrier to entry for PET imaging, while preserving quantification accuracy. Dr. Bartlett currently has a Nation Institute of Mental Health K01 Award to apply such methods to investigate the biological mechanisms underlying the depressogenic effects of stress in a multimodal PET/magnetic resonance imaging (MRI) study utilizing MRI modalities such as structural MRI (to derive brain volume and thickness) and MR spectroscopy (to quantify glutamate concentration).
