David A. Florin, LCDR, MSC, USN

Assistant Professor


LCDR Florin completed his undergraduate training in Biology at the State University of New York at Stony Brook, NY in 1982. After graduation, he honed his professional experience by working with the New York Zoological Society and then environmental firms involved in the Superfund hazardous waste site investigations. He received his Masters degree in Biology from Adelphi University, Garden City, NY and then joined on with the Navy as an Environmental Health Officer (EHO) in 1993. While as an EHO, he completed tours at the Naval Hospital Charleston, SC and Naval Hospital Groton, CT. In 2000, LCDR Florin qualified for Entomologist and served as Operations Officer for the Navy Disease Vector Ecology and Control Center at the Bangor Submarine Base, WA. After completing a deployment to Iraq, LCDR was awarded Duty Under Instruction whereby he entered into the Doctoral Program of Medical Zoology at USUHS. In 2006, LCDR Florin graduated with a dissertation centered on the morphological and molecular study of a sand fly species that has medical importance to the military. His next position was overseas at the US Naval Medical Research Center Detachment in Lima, Peru as Program Director of Entomology where he secured over $500,000 in 2007 for funded research from diverse sources such as the Military Infectious Disease Research Program, Global Emerging Infectious Disease Surveillance, Henry Jackson Foundation, The Johns Hopkins School of Medicine, and the University of California. In 2008, he returned to the Washington DC area by accepting an assignment as the Navy Liaison at the Armed Forces Pest Management Board, a position that placed him "front and center" in the diplomacy involved in the regulation of pesticides that are of interest to the military. Currently LCDR Florin serves as Assistant Professor within the Medical Zoology curriculum where he is able to share his wide-ranging expertise and experience not only to the students, but his fellow colleagues on the staff.
