Faculty

Dr. Cameron R. Homeyer | EMAIL | CV
Associate Professor, Associate Director for Graduate Programs in the School of Meteorology, Chesapeake Energy Professor of Climate Systems Science, and Head of the CCC Research Group

Dr. Homeyer joined the faculty in the School of Meteorology in July 2014 and shortly thereafter established the CCC Research Group. He completed all three of his degrees (B.S. in Meteorology, M.S. and Ph.D. in Atmospheric Sciences) from 2004-2012 at Texas A&M University in College Station, Texas prior to receiving a postdoctoral fellowship in the Advanced Study Program at the National Center for Atmospheric Research (NCAR) from 2012-2014. He served as Associate Director for Undergraduate Studies in the School from 2017-2018 before moving into a similar role supporting the Graduate Program. Dr. Homeyer’s research is concentrated in two areas: upper troposphere and lower stratosphere (UTLS) studies and severe storms. Radar, satellite, and aircraft observations are used heavily in his work, supplemented by convection allowing model simulations and reanalyses. He is known to harbor strong opinions about the definition of the tropopause and excitement for tropopause-overshooting convection (thunderstorms). Brief summaries and examples of ongoing research activities are summarized on the Research page of this website.

Graduate Students

Amanda Murphy EMAIL
Ph.D. Student





Amanda joined the CCC group in December 2019 and is studying severe storms using an extensive set of 5-min NEXRAD WSR-88D radar observations, merged into large-area GridRad composites for severe weather events (GridRad-Severe; ~1000 events from 2010-2019). Her work is focused on unraveling unique indicators of tornadic cells within mesoscale convective systems, accomplished through composite analyses of the radar observations and, ultimately, development of an MCS-focused machine learning model for next-hour tornado prediction. Amanda is supported by the NSF AI Institute AI2ES (https://www.ai2es.org). She completed a B.S. in Meteorology at the University of Illinois in May 2016 and an M.S. in Meteorology at OU in August 2018.

Emily Tinney EMAIL
Ph.D. Student




Emily joined the CCC group in August 2018 and is studying the impact of convection on the composition of the upper troposphere and lower stratosphere using ground-based radar observations, satellite-based trace gas observations, and a trajectory model. She completed a B.S. in Meteorology at Central Michigan University in May 2018 and an M.S. in Meteorology at OU in December 2020.

Andrea Gordon
Ph.D. Student





Andrea joined the CCC group in June 2018 as an undergraduate researcher and has extensive experience running and analyzing trajectory calculations and is participating in and supporting the DCOTSS field project. She has also run and analyzed a set of idealized simulations of tropopause-overshooting convection since late 2020, published in 2022. Andrea completed a B.S. in Meteorology at the University of Oklahoma in May 2021 and is currently pursuing a Ph.D. degree in the CCC group, analyzing DCOTSS data and continuing modeling work.

Undergraduate Researchers

Rachael Auth




Rachael joined the CCC group in April 2021 and is helping manage our ozonesonde activities. This includes lab setup, conditioning of the instrumentation, preparing the entire instrument package for launch, and ultimately, analyzing the data. The primary target for ozonesonde activities will be thunderstorm outflows (both active and aged). She is currently pursuing a B.S. in Meteorology at the University of Oklahoma with an expected graduation date of May 2023.
