Research Interests
I am interested in the impacts of lightning and other atmospheric electrical phenomena, as well as solar events, on the near-Earth space environment. Lightning is potentially the principal driver of the global electric circuit (GEC), and very low frequency (VLF) waves generated by lightning are key drivers of electron precipitation from the Earth's radiation belts, and can be used as a diagnostic of the Earth-ionosphere waveguide (EIWG) and lower ionosphere. I use global lightning data, as well as data from numerous spacecraft, to address these research topics. To that end, I help build and maintain stations for the World Wide Lightning Location Network (WWLLN; https://wwlln.net/), which uses ~100 stations all over the world to detect VLF waves generated by lightning and locate lightning strokes. I am also involved in the design, fabrication, validation and deployment of stratospheric balloon payloads. In particular, I designed an instrument used to measure the 3-axis electric field and conductivity in the stratosphere, in order to compare the fair-weather return current of the GEC to global thunderstorm area.
