Research/Academic Interests
Dr. Omidvari's research interest is developing quantitative in vivo molecular imaging techniques for studying the immune system and clinical translation of these methods. Her current work is focused on T cell imaging radiotracers and uses mathematical modeling approaches with total-body positron emission tomography (PET) technology for quantitative assessment of immune response in various disease conditions, such as cancer, long COVID, and Alzheimer's disease.
