Description: The University of Rochester’s Ice Core and Atmospheric Chemistry Laboratory, located in the Department of Earth and Environmental Sciences, has an opening for a postdoctoral position. The successful candidate will work with Dr. Aparajeo Chattopadhyay and Professor Vasilii Petrenko on an atmospheric chemistry gas kinetics project recently funded by the National Science Foundation’s
Division of Atmospheric and Geospace Sciences (NSF-AGS). In this laboratory project, we aim to investigate the kinetic isotope effects (KIEs) of methane (CH 4 ) in atmospheric removal through reactions with the hydroxyl (OH) radical and the chlorine (Cl) atom, employing a temperature and pressure-controlled laser photochemical reactor coupled with online and offline spectroscopic determinations of relevant chemical
species for kinetic analysis. Tunable Infrared Laser Direct Absorption Spectroscopy (TILDAS) is the primary analytical technique used in this study for high-precision measurement of methane isotopologues ( d 13 C and d D). The improved uncertainty in our measured KIEs is expected to better constrain the global CH 4 budget from atmospheric CH 4 isotopic measurements. For more information about this
