UCF AVS Astrochemistry Webinar: Dr. Christopher Shingledecker

Cosmic Rays in Astrochemical Models Material in the interstellar medium is subjected to bombardment by several types of ionizing radiation including cosmic rays, stellar winds, x-rays, and gamma-rays. It is known that such radiation can have a significant physicochemical impact on interstellar environments, and a large body of experimental work has shown that the interaction between such energetic particles and low-temperatures ices can result in the formation of complex - even prebiotic - molecules. Even so, modeling the chemical effects of cosmic ray collisions with interstellar dust grain ice mantles has proven challenging due to the complexity and variety of the underlying physical processes. In this talk, recent work on this subject by us is reviewed and the possible applications to better understanding the chemistry of interstellar space is highlighted. Speaker Biography: Christopher N. Shingledecker is an Alexander von Humboldt Foundation postdoctoral research fellow, with appointments at the Max Planck Institute for Extraterrestrial Physics Center for Astrochemical Studies (CAS@MPE), and the Institute for Theoretical Chemistry at the University of Stuttgart. In the Fall of 2020, he will begin his appointment as an Assistant Professor of Physics and Astronomy at Benedictine College. His research is in theoretical computational astrochemistry, with a focus on the interactions between interstellar dust-grain ice mantles and cosmic rays. From the University of Virginia, he received both a B.Sc., summa cum laude, Phi Beta Kappa (2013) and later a Ph.D. (2018) with Eric Herbst. He is one of the recipients of the 2017 Rao Prize, had two papers in Physical Chemistry Chemical Physics designated HOT articles, and has had his work highlighted in the 2019 Coalition for Academic Scientific Computation (CASC) brochure for US federal lawmakers.
