Denise Gregoire-Lucente


Denise Gregoire received her B.Sc. in biology from the University of Minnesota Duluth in 2004. During her time at the USGS Southeast Ecological Science center, she has worked as a biological technician for numerous programs including the Amphibian Research and Monitoring Initiative (ARMI), the Nonindigenous Aquatic Species (NAS) Database, and a brief stint with the Sirenia Project on their Manatee Individual Photo-identification System (MIPS). Currently Denise is a fisheries biologist in the lab of Dr. Pam Schofield, examining the ecology of non-indigenous species of Florida, specifically freshwater fishes.
