Dr. Janowski completed his residency in neurosurgery at the Medical University of Warsaw, Poland in 2009, and a year later he defended his PhD thesis in neuroscience at the Mossakowski Medical Research Centre, PAS, Warsaw, Poland. In 2011 he joined the Department of Radiology at Johns Hopkins University as a post-doctoral fellow and his career progressed to Associate Professor in 2016. In 2019 he moved to the Department of Diagnostic Radiology and Nuclear Medicine at the University of Maryland, Baltimore. Dr Janowski’s research interests center on adding advanced imaging to accomplish precision medicine in neurointerventions. He is using radiolabeling and magnetic labeling of therapeutic agents to deliver them to the central nervous system using real-time interventional PET and MR imaging.

Dr. Janowski is the Co-Director of the Program in Image Guided Neurointerventions (PIGN).
