Description:  I have always been heavily involved in field work aimed at better understanding meteorological and chemical processes in the atmosphere, even early in my career as a student. After my undergraduate training, I was fortunate to participate in numerous multi-agency field campaigns. These experiences in the field propelled me towards research which resulted in my pursuit of a Ph.D. at the University of Houston. My Ph.D. work was focused on atmospheric chemistry, specifically tropospheric ozone, and how it is impacted by meteorological variability. Using a combination of field measurements, models, and machine learning techniques, my research has shown how sensitive ozone chemistry can be in relation to meteorological processes. I have also gained valuable experience operating and maintaining a variety of chemical and meteorological instrumentation. This culmination of research and field work has resulted in an appreciation for the complexities of the atmosphere and what remains to be discovered.
