Evolution of Osmoregulation: salinity tolerance in sea lampreys

The Karlstrom and McCormick Labs investigate how hormones control osmoregulation in fish, and have an NSF-funded project to examine the evolution of hormonal control of salinity tolerance in a basal vertebrate, the sea lamprey. This position is for students ready to pursue a serious honors thesis project, including summer research. The student will work with a graduate student and/or postdoctoral fellow, and research will be performed in the Karlstrom lab in the Biology Department and/or in the McCormick Lab the U.S.G.S. S.O. Conte Anadromous Fish research facility in Turners Falls, MA.

Molecular genetic mechanisms of host-microbe mutualism

The Wang Lab, located in the Life Science Laboratories, is interested in the mechanisms of beneficial host-microbe interactions. Our experimental system is the symbiosis between legumes and nitrogen-fixing rhizobia, with important economic and environmental relevance, as well as similarities to pathogenic interactions. The BURA student will be engaged in dissecting the genetic basis of the nitrogen-fixing symbiosis, in particular characterizing the defects in host mutants unable to sustain a successful symbiotic relationship.
