He received his Ph.D. at UCLA under Dr. Paul Mischel in 2011 and conducted his post-doctoral work with Drs. Caius Radu and Johannes Czernin at UCLA. Dr. Nathanson’s current work focuses on investigating the highly interconnected relationship between aberrant signal transduction and metabolism in cancer, with a strong emphasis on using positron emission tomography (PET) to dynamically measure changes in tumor metabolism with therapies that interfere with oncogenic signaling.
