I’m in a 100% teaching appointment, so research is not written into my job description. However, listed below are the contributions I’ve been able to make.
Climate Change/Crop Productivity Web App
I recently worked on a project with Penn State’s Center for Environmental Informatics that involved the development of a web app that provided access to maps showing the growing potential of various crops (based on soil characteristics and climate) along with the growing potential of those same crops under various climate change scenarios.
Air Mass Atlas
My Master’s thesis involved developing a methodology for drawing air mass boundaries based on surface weather observations made at stations across the U.S. That work left off as a tedious set of manual steps, so in recent years I revisited the project with the goal of automating the process and building an atlas of daily air mass maps. The atlas — which I’ve stopped maintaining — provided access to maps covering 1948-present.
