Research Interests

During my PhD, my research focused on observational studies of the atmospheric boundary layer. Our group installed an extensive suite of environmental instrumentation as part of the MATERHORN field program. We utilized the data to investigate near-surface, countergradient heat fluxes that sometimes occur during the evening transition. We also studied the development and structure of downslope (katabatic) flow that develops under stable conditions over land. Additionally, I co-led a wind resource analysis for utility-scale energy production in Belize. In addition to the resource analysis, the data are being used to quantify the anisotropic development and decay of turbulence through the morning and evening transitions.

At Lawrence Livermore National Laboratory, I have shifted directions a bit and am currently working on atmospheric source attribution utilizing Bayesian inversion and machine learning techniques.
