Mark Sellmyer

Assistant Professor University of Pennsylvania

I am an Assistant Professor in the Department of Radiology at the University of Pennsylvania with a secondary appointment in the Department of Biochemistry and Biophysics. I co-founded and direct the Penn Center for Translational Chemical Biology (CTCB) to grow interest and facilitate training in Chemical Biology at Penn. Also, I direct the PET Center, a university core in the Department of Radiology, which aims to bring new radiopharmaceuticals for imaging and radiotherapy into clinical practice. My research group comprises investigators from basic and clinical domains, with expertise broadly in synthetic chemistry, cancer biology, gene and cell therapy, and immunology.
