About Us

Lakes and ponds are superb natural laboratories for understanding how the ecological world functions. Like plants and animals on ocean islands, the populations and communities of organisms in lakes are more isolated from exchange with nearby habitats than are their terrestrial counterparts. The microbes, algae, plants and animals that live submersed beneath the water’s surface are nearly all restricted to their liquid environment, unable to cross the land that surrounds them. Thus confined, their interactions are often intense, easily discerned, and complex in fascinating ways. Undergrads, grad students and postdocs, in the Hairston Lab take part in research on these topics.

Lindsay Schaffner

Lab Manager, until recently

Lindsay is interested in understanding how biological and physical processes affect conservation and management issues in freshwater ecosystems. Lindsay's thesis focused on rapid evolution and eco-evolutionary dynamics in the consumer species, Daphnia, in a temperate lake in upstate New York.
She is now Executive Administration Assistant, Cornell Institute of Biotechnology

Masato Yamamichi

Visiting Associate Professor

Masato is an Associate Professor at the University of Queensland, Australia, and has been visiting EEB for collaborative research in the Hairston and Ellner Labs. Masato studies eco-evolutionary dynamics of predator-prey systems by using methods in mathematical ecology and population genetics.

Rachel Wilkins

Graduate student

Rachel is interested in the abundance and distribution of freshwater calanoid copepods. Rachel studies the habitat, diet and population genetics of rare and common copepods to understand what constrains rare species, and how common species overcome these constraints in locations such as the Adirondack Mountains of NY and British Colombia, Canada.

Corson Hall @ Cornell

Cornell University offers a variety of excellent opportunities for in situ study of living organisms from fresh water. Off-campus locations such as the Cornell Experimental Ponds Facility and Cornell Biological Field Station provide facilities for replicating experiments in natural and controlled aquatic environments.​
