Bio: I spent my childhood summers on the Chesapeake Bay, living next to beautiful salt marshes and fishing villages on Kent Island. Watching crab fishermen bring in their catches, I noticed that year after year, the number and size of crabs being caught decreased. The population was declined, affecting my neighbors and friends. I developed a personal interest in the study of fisheries management, invertebrate physiology and behavior.  It was only natural to migrate to the Duke Marine Lab.

For my dissertation, I lived in the Florida Keys studying spiny lobster reproduction.  My dissertation work sought to understand the implications of biological rhythms on the larval behavior of phyllosoma larvae (baby spiny lobsters).  I conducted laboratory experiments to determine how behavior might affect the transport of larvae around the Caribbean. Today, I live in Florida working for the Everglades Restoration Program (CERP). 

Hobbies: Scuba Diving, Swimming, Going to the Beach, Hiking, Camping, and Travel.
