Interested in weather for as long as I remember, I went to Valparaiso University (Indiana) to study meteorology as an undergraduate, then undertook graduate studies in meteorology at the University of Oklahoma. I joined the Department of Earth and Atmospheric Sciences at UNL in fall 2011.
My research has mostly been related to severe weather. I have focused on defining and understanding polarimetric radar signatures in Southern and High Plains supercells, with special emphasis on the near-tornado portion of the supercell lifecycle. In my most recent work, I’ve been trying to learn how hydrometeor distributions vary in supercell storms forming in environments with different wind or moisture profiles. Then, I’ve sought to learn how these differing microphysical distributions may lead to changes in storm evolution, especially related to the rear flank downdraft and mesocyclone. Some prior work looked at cloud-to-ground lightning production in strongly-forced, low-instability convective lines. Following personal curiosity, I also undertook and published a study on the meteorology involved in visibility of crepuscular and anticrepuscular rays on the Southern Plains.
I’m planning for future research interests to follow along similar lines, with a few additions. I’d like to continue studying polarimetric signatures of different convective modes to learn about their microphysics, particularly as the WSR-88D network is upgraded. Modeling studies to learn about hydrometeor evolution are also a possibility, as well as studies seeking to explore how hydrometeor distributions and evolution vary geographically. I’d also like to begin studies at the ecology-atmosphere interface, with a possible focus on how land use changes affect local weather on short and long timescales.
