Overview of Research Interests:

Numerous natural processes drive geophysical electric and magnetic fields. In my research, I use these fields to further our understanding of Earth’s atmosphere and space environment. My previous and current work has focused on a diverse group of natural electric and magnetic field sources, including lightning, middle atmospheric discharges, solar-terrestrial effects in the ionosphere and magnetosphere, and sources within the Earth’s crust. I have experience in both experimental techniques and theoretical modeling. This includes building and testing instrumentation and acquisition systems, analyzing data, and developing numerical models. My immediate future work plans include projects related to in situ measurements inside and above thunderstorms, ground-based sensing of middle atmospheric discharges that affect the ionosphere, investigating the geomagnetic perturbations from dc to low frequency radio bands, and evaluating lightning in tropical cyclones globally.

• Lightning and thunderstorm effects in the middle and upper atmosphere 
• Geomagnetic perturbations driven by mechanisms within the Earth’s crust and solar-terrestrial interactions 
  
• Lightning and tropical cyclone intensity change 
• Thunderstorm electrification and the global electrical circuit
