 Faculty projects

Dr. Harold Gurrola

•Upper mantle transition zone (410 to 660 km depths) and the lithosphere using P-to-S converted waves (receiver functions) or PP underside reflections. 


•The crust (mid crust and Moho) using gravity and seismic methods


•Shallow features such as playa lakes using electrical and seismic methods.

Dr. Jen Henderson

  • Building knowledge of how compound hazards (e.g. tornadoes and storm surge) within the shifting vulnerabilities of Covid-19 are understood, assessed, and communicated by meteorologists and public safety officials during landfalling tropical cyclones 
  • Understanding through an interdisciplinary team lens why tornado disaster potential and mortality is greater in the Southeast compared to any other U.S. region and how to co-develop actionable science with high-risk communities to reduce social vulnerability.  
  • Through mixed-methods research developing theories of how compound and cascading hazards (e.g. drought and wildfires) impact and magnify harm and alter expert conceptualizations of vulnerability and resilience.  
  • Development of secondary analysis frameworks, laboratory practices, and data sharing ethics for qualitative methods in disaster contexts.
