Education

1979-1981 University of Colorado; Boulder, CO; Department of Geological Sciences; geology major.

1981-1983 University of Texas; Austin, TX; Department of Geological Sciences; B.S. in 1983 with Highest Honors from the College of Natural Sciences and Special Honors from the Department of Geological Sciences; Honors Thesis title: Molluscan Species Richness from the K/T Boundary to the Upper Eocene; Thesis advisor: Thor A. Hansen.

Research Interests

My interest is in inferring evolutionary and sedimentary patterns and processes using fossil and living organisms. My current research involves marine biofouling, functional morphology, and carbonate production rates of bryozoans.

Bryozoans
Cool water carbonate production rates

Evolution of epibiosis
Biomechanics of bryozoan feeding
Geoarcheology, Chesapeake Bay, Virginia

Appraisal of fossil collections – I evaluate the value of fossil collections for estate settlements, making tax deductible gift donations, etc.
