Education

  • BS, Florida Atlantic University —Geology
  • MS, Florida Atlantic University —Geology
  • PhD, ABD, Texas A&M University - Geology

Courses Taught

GEOS 101/102 Dynamic Earth Lecture and Lab
GEOS 104 Oceans and Atmospheres Lab

Professional Interests

Marine Invertebrate Paleontology, Carbonate Sediments, Paleoceanography

My research uses SEM and Electron Microprobe to measure Ca/Mg ratios of permineralized plants and marine invertebrates (echinoderm crinoids) found in Late Pennsylvanian coal balls of North America. I am also interested in geometric morphometric studies of bivalves and other marine invertebrates.
