Richard Lenski

He was elected to the American Philosophical Society in 2018.

In August 2013, having been inspired by a presentation by Titus Brown on the role of social media in science, Lenski began blogging at Telliamed Revisited and tweeting as @RELenski.

On February 17, 2010, he co-founded the NSF Science and Technology Center for the Study of Evolution in Action, known as the BEACON Center.

Lenski's research has received considerable attention, including lengthy discussion in Carl Zimmer's book on E. coli, Microcosm, and in Richard Dawkins' book on the evidence for evolution, The Greatest Show on Earth. Included in Dawkins' discussion was a description of the dialog Lenski had in 2008 with Andrew Schlafly, creator of Conservapedia, which Schlafly initiated as a reaction to reports of Lenski's description of the evolution of aerobic citrate usage in one of the long-term evolution experiment populations. These same findings were later cited by the creationist Ken Ham in a debate over evolution with Bill Nye. Lenski strongly criticized Ham's citation of his work and the conclusions Ham drew from it.

Lenski won a Guggenheim Fellowship in 1991 and a MacArthur Fellowship in 1996, and in 2006 he was elected to the United States National Academy of Sciences.

The E. coli long-term evolution experiment is an ongoing study in experimental evolution led by Richard Lenski that has been tracking genetic changes in 12 initially identical populations of asexual Escherichia coli bacteria since 24 February 1988. The populations reached the milestone of 50,000 generations in February 2010.

Richard E. Lenski is the son of sociologist Gerhard Lenski and poet Jean Lenski (née Cappelmann). He is also the great-nephew of children's author Lois Lenski and the great-grandson of Lutheran commentator Richard C. H. Lenski. He earned his BA from Oberlin College in 1976, and his PhD from the University of North Carolina in 1982.

Richard Eimer Lenski (born August 13, 1956) is an American evolutionary biologist, a MacArthur "genius" fellow, a Hannah Distinguished Professor of Microbial Ecology at Michigan State University, and a member of the National Academy of Sciences. Lenski is best known for his still ongoing 32-year-old long-term E. coli evolution experiment, which has been instrumental in understanding the core processes of evolution, including mutation rates, clonal interference, antibiotic resistance, the evolution of novel traits, and speciation. He is also well known for his pioneering work in studying evolution digitally using self-replicating organisms called Avida.
