We have two new undergraduates joining us this summer. Liz Rosario is from the University of Puerto Rico and is funded through the NIH MARC program. Marin Bray is a Purdue student funded through the Summer Stays program. Both Liz and Marin will be working with Spencer to study the effects of habitat restoration on the health and abundance of amphibians in Tippecanoe County. Welcome to the lab, Liz and Marin!
