Hadyn Kistle is a Ph.D. student working with Dr. Craig Marianno and Dr. Shaheen Dewji. Her interests include nuclear forensics and health physics applications following radiological and nuclear incidents. Kistle’s research will conduct pre- and post-detonation examination of particles from a radiological dispersal device (RDD) to establish changes in chemical signatures, including composition and morphology. Results from the experiments will also provide particle characteristics for investigation into health effects using MCNP. Kistle graduated in 2012 from the University of Tennessee, Knoxville, with a B.S. in Nuclear Engineering. She worked with the Chemistry Division at Los Alamos National Lab in 2016, and has continued working at LANL with M Division (Explosive Science and Shock Physics).
