Research Interests

My current research interests fall dominantly within the fields of Biomineralization and Paleoecology. Ongoing work using modern and fossil marine invertebrates involves investigation of fundamental questions in Natural Sciences, within several subdisciplines ranging from paleoclimatology to materials science, in a multidisciplinary research framework. Some examples are given as follows:

Biomineralization

1) Climatic and environmental proxies
2) Biomineral crystal structure, growth and physical properties
3) Development of microscopy and analytical techniques for biomineral characterization

Paleoecology

1) Biogeochemistry of fossils
2) Late Paleozoic paleoecology and paleoclimatology
3) Fossil brachiopod faunas
Conjugate research interests also include investigating linkages between marine and non-marine ecosystems, carbonate sedimentology, and fossil invertebrate biomechanics.

Current Research Projects

1) Crystallography (EBSD) of fossils (brachiopods, foraminifera, eggshells, shark teeth) for clumped isotope applications [in collaboration with colleagues at Johns Hopkins, Texas A&M, and UCLA].

2) Development of atom probe tomography (APT) for minerals.

3) Biomineralization in Paleozoic corals [in collaboration with colleagues at the Universidad Complutense in Madrid, Spain].

4) Microstructural characterization of the mineralization in pearls [in collaboration with colleagues at Universite Paris XI-Orsay, France].

5) Biomineralization of giant clams [in collaboration with Prof. Aharon, UA] and otoliths [in collaboration with colleagues in Peru].

6) Unusual biomineral structures in trilobites [in collaboration with Dr. Thomas Hegna at Western Illinois University].

7) Growth and geochemistry of brachiopod shells [in collaboration with Dr. Anthony Aldridge (New Zealand) and Prof. Kazuyoshi Endo (University of Tokyo, Japan)].
