I joined GSL (then GSD) within the Assimilation and Verification Innovation Division (AVID; formerly the Assimilation and Modeling Branch AMB) in 2010. Since that time, my research interests have revolved around the use of observations in numerical weather prediction, applications of high-resolution model guidance in complex terrain, and data mining. I have played a key role in maintaining real-time experimental model forecasts from the hourly Rapid Refresh (RAP) and High-Resolution Rapid Refresh (HRRR), and have carried out numerous retrospective experiments for the purpose of various aspects of data assimilation or model physics improvements. I have been involved with many projects and outreach efforts associated with new capabilities developed in the HRRR system, including especially the HRRR-smoke system for prediction of wildfire smoke plumes. Outside of work, I am currently pursuing a PhD in Atmospheric Science; in my very limited free time, I enjoy hiking, backpacking, and trail running.
