# Elena Litchman

Elena Litchman is a professor of aquatic ecology at Michigan State University known for her research on the consequences of global environmental change on phytoplankton.

## Education and career

Litchman received an Honors Diploma in biology from Moscow State University, Russia, and a Ph.D. in ecology from the University of Minnesota in 1997. Following graduate work, Litchman held postdoctoral positions at the Smithsonian Environmental Research Center, the Swiss Federal Institute for Aquatic Science and Technology, and Rutgers University. From 2003 to 2005, Litchman was a research scientist at Georgia Institute of Technology. In 2005, Litchman took a position in the Zoology Department of Michigan State University and the W.K. Kellogg Biological Station. She has been named a MSU Foundation Professor at Michigan State University where she works in the Department of Integrative Biology.

## Research

Litchman's Ph.D. research examined the impact of changing light levels on competition in phytoplankton. She introduced the use of trait-based ecology for phytoplankton in papers published in 2007 and 2008. Prior to these publications, trait-based ecology had been implemented in terrestrial science and Litchman was the first to apply these ideas to marine research. Key traits in phytoplankton include light, nutrient use, morphology, predation, and temperature, and Litchman has combined these traits to mathematically define phytoplankton community structure. Litchman's research has examined the connection between the size of phytoplankton over evolutionary time and nutrient limitation which, in turn, impacts marine food webs under changing climates. Through eco-evolutionary modeling, Litchman's research has shown that in the future warmer oceans will cause phytoplankton to shift towards polar regions.
