Paweł Moskal is an inventor of cost-effective positron emission tomography (PET) based on plastic scintillators and a method of positronium imaging. He conceived and headed a medical experiment demonstrating the first positronium images of the human brain in vivo. He is a professor of physics and the head of the Cluster of Nuclear Physics Departments at Jagiellonian University, Poland. He has supervised 32 PhD students, coauthored 42 patents, and published more than 450 scientific articles. He founded and leads the J-PET group, constructing the first total-body PET system from plastic scintillators with the capability of multiphoton imaging, including positronium and entanglement imaging.
