Today’s interview features Dr. Lauren Jackson, a nationally known expert in the field of tumor and normal-tissue radiobiology. She is especially recognized for her expertise in medical countermeasure development for acute radiation sickness and delayed effects of acute radiation exposure. Lauren is the deputy director of the Division of Translational Radiation Sciences within the Department of Radiation Oncology at the University of Maryland School of Medicine. Lauren, who also goes by Isabel, received her bachelors in science in microbiology from North Carolina State University in 2006, and her PhD in pathology from Duke University in 2012. She currently is a principal or collaborating investigator on a number of industry and federally sponsored contracts and research grants. She has published extensively on the characterization and refinement of animal models of radiation-induced normal tissue injury that recapitulate the response in humans. Models developed in Lauren’s laboratory have gone on to receive FDA concurrence as appropriate for use in medical countermeasure screens. Lauren is a senior associate editor for Advances in Radiation Oncology, a journal of the American Society of Therapeutic Radiation Oncology, and serves as an ad hoc reviewer for several peer-reviewed journals. She also is the author of several book chapters on normal tissue tolerance to radiation, mechanisms of injury, and potential therapeutic interventions.

Lauren then talks about how thanks to that experience, she decided journalism and political science weren’t the right majors for her. 7:38: Dawn points out that when Lauren first went to college, she took the minimum number of science classes.  Lauren goes on to talk about how after spending time in D.C., she ended up applying to North Carolina State University and switching her major to microbiology. 8:52: While at N.C. State, Lauren worked for Dr. Hosni Hassan, an expert on Oxidative Stress. Dawn asks Lauren about the focus of her research with Dr. Hassan. 9:58 Dawn talks about how when Lauren was an undergrad at N.C. State, she became interested in tumors and cancer treatment, and found a professor down the road at Duke University who was doing interesting work in that area. Dawn asks Lauren if that’s why she ended up going to Duke for her doctorate. 10:52 Dawn asks Lauren to elaborate on how her background in journalism and political science connected her towards the path of radiation countermeasure research.  11:42 Dawn points out that as a graduate student at Duke, Lauren took part in projects that looked at radiation injury. Dawn asks Lauren to give an overview of what sort of work was involved in the projects.  12:46 Ken asks Lauren to explain the difference between clinical radiation exposure and radiation that someone would experience as a consequence of a nuclear attack. 13:59: Ken shifts the conversation to human space flight,
