Johan K E SpetzJohan Spetz (born 1986) is currently a postdoctoral research fellow at the John B. Little Center for Radiation Sciences at Harvard T.H. Chan School of Public Health. With a background as a Medical Physicist (M.Sc. 2010, University of Gothenburg), John Spetz's PhD (2017, University of Gothenburg) focused on peptide receptor radionuclide therapy of small intestine neuroendocrine tumors and biological effects of radiation. This research prompted a further interest in biology, and lead Johan Spetz to enter a postdoctoral research position under the mentorship of Kristopher Sarosiek at Harvard T.H. Chan School of Public Health, with a focus on the regulation of apoptotic priming in response to stress such as irradiation. Specifically, Johan Spetz has worked on measuring dynamic regulation of apoptotic sensitivity in healthy as well as cancerous mammalian cells throughout development and aging, on a single cell level. Through this research, Johan Spetz has identified subsets of cells which are vulnerable to genotoxic stress, within otherwise resistant tissues. Johan Spetz has also worked on the development of functional assays to measure defects in the intrinsic apoptotic pathway, which may be targeted to enhance cancer therapeutics and/or reduce toxic side effects of treatment. Johan Spetz has published 19 articles in peer-reviewed scientific journals and 90+ scientific conference abstracts. Read More Read Less
