Biography

Joel Karp is a Professor in the Department of Radiology and the Department of Physics & Astronomy at the University of Pennsylvania. He completed his Ph.D. in nuclear physics from MIT in 1980 and joined the faculty at the University of Pennsylvania in 1983. His research primarily focuses on improving and characterizing the performance of Positron Emission Tomography (PET) technology, including advancements in front-end electronics, detector design, data correction techniques, and 3D image reconstruction algorithms. His work has led to the development of fully 3D PET scanners and innovative imaging systems based on scintillation detectors, which have been implemented commercially for both human and animal imaging. Karp has been instrumental in developing time-of-flight (TOF) imaging systems and has collaborated with industry partners, which led to the adoption of TOF technology in modern PET/CT scanners. Currently, he is leading a team at Penn in the development of the large axial field-of-view PennPET Explorer instrument, which enables new opportunities for clinical research investigations.
