He received his Ph.D. in 1998 from Northeastern University, Boston, Massachusetts. Following post-doctoral work in Boston and Hawaii, he came to The Citadel in 2005. His expertise is in the biology of invertebrate larvae, molecular evolution, deep-sea biology, and the biology of symbiosis, in particular the association of barnacles with sea turtles. He is a subject editor for the international journal&nbsp;<em>Marine Biology Research<\/em>&nbsp;and supervises graduate students in their research as an adjunct faculty member of the College of Charleston\u2019s Graduate Program in Marine Biology. His teaching specialties include Introduction to Biology, Marine Biology, and Invertebrate Zoology.
