Current Research Projects

I am currently funded by the National Science Foundation through a CAREER grant (EAR1553878) to explore the effects of volcanic lightning on both natural and manufactured volcanic ash samples through a series of lightning experiments.  My research group conducts various studies on explosive eruptions and their interaction with the atmosphere, including ice nucleation.

Courses Taught

  • GEO 314: Igneous & Metamorphic Petrology
  • GEO 416/516: Volcanology
  • GEO 424/525: SEM Methods in Geology
  • GEO 495: Field Course
