Ansel Hillmer, PhD

Associate Professor of Radiology and Biomedical Imaging and Associate Professor of Psychiatry and of Biomedical Engineering; Associate Director of Imaging, Positron Emission Tomography (PET)



Ansel obtained his Ph.D. in Medical Physics from the University of Wisconsin, Madison in 2014. His research program features core areas of translational characterization of novel PET radiotracers, developing new imaging paradigms to improve quantification of brain neurobiology, and human neuroimaging research studying mechanisms underlying diverse psychiatric conditions. Research efforts are complemented by didactic activities lecturing at Yale and individual mentoring of trainees. Current projects include characterizing novel PET radiotracers of immune-related targets in the brain; developing novel imaging paradigms to study acute alcohol effects on neuroimmune and glutamate systems; assessment of dopamine release from smoked cannabis; method development for analyzing multimodal imaging data from fMRI-PET or PET-PET datasets; and implementing Independent Component Analysis (ICA) to identify different sources of PET radiotracer uptake.
