Richard Lenski, a world-renowned evolutionary biologist whose long-term experiment of the microorganism Escherichia coli has been running for more than three decades, will deliver the 2023 Darwin Day Lecture at Vanderbilt University on Wednesday, Feb. 8. Read More

Local students from Stratford and Overton high schools got to excavate 70 million-year-old oysters, clams and shrimp at the Evolutionary Studies Initiative fossil search. The event aimed to teach students about food webs and to connect students with ESI grad students, postdocs and faculty to talk about college, science and evolution. Read More

Annie Hatmaker, along with a team of researchers including her adviser, Cornelius Vanderbilt Professor of Biological Sciences Antonis Rokas, recently published a study identifying the differences in virulence among Aspergillus species, a common human-pathogenic genus of fungi. Read More

Laura Novick and Jingyi Liu published a paper highlighting the importance of intentionally and thoughtfully designed figures to explain evolutionary relationships and overcome preconceived misconceptions. Read More

Julián F. Hillyer, professor of biological sciences, and his research team discovered how mosquito immune and circulatory systems are related. This work may lead to the development of novel strategies that protect beneficial insects or harm detrimental ones. Read More

Feedback from editors and reviewers of academic journals is an often-understated driver of new research directions. Assistant Professor of Earth and environmental sciences Simon Darroch, found this to be the case for his new paper examining the differences between geographic ranges of species historic and living.

Amanda Lea, assistant professor of biological sciences, has been named to the 2022–24 cohort of the Canadian Institute for Advanced Research Azrieli Global Scholars in recognition of her outstanding early-career research and interdisciplinary work. Lea’s research interests span evolutionary biology, genomics and human health.  Read More

Vanderbilt and Arizona State University microbiologists explore the effects of feast and famine cycles on E. coli, providing insight into how the bacterial communities that reside in our guts, with our crops, in lakes and streams, and beyond become so complex. Read More

Mosquito-borne diseases like malaria represent an ongoing global health crisis of (literally) biblical proportions. LJ Zwiebel has identified the biological factors that help female mosquitos mate, suck blood and sense environmental threats. Est. reading time: 1.5 mins. Read More

Amanda Lea, assistant professor of biological sciences, has been named a 2022 Searle Scholar, an honor bestowed on 15 exceptional young faculty in the biomedical sciences and chemistry. Lea will receive $300,000 in flexible funding to support her work over the next three years. Read More

Graduate student measures the coevolution of genes in genomes; method may fundamentally change how we identify genes with similar functions. Read More

Growing up in a small community has its advantages, but if you want to learn from world experts, you may have better luck in a big city. This is the case in the world of birds as well. Large populations of birds might be better able to maintain complex songs than small populations – all because of access to high-quality tutors. Read More

Members of the Evolutionary Studies Initiative took a field trip to Coon Creek Science Center (CCSC) to dig for fossils. Read More

Jacob Steenwyk, a sixth-year doctoral student studying biology in The Rokas Lab, is a recipient of the 2022 Harold M. Weintraub Graduate Student Award presented by the Fred Hutchinson Cancer Research Center. He is the second Vanderbilt student ever to receive this honor. Read More

The Vanderbilt Evolutionary Studies Initiative welcomes image forensics detective Elisabeth Bik for the inaugural J.T. Scopes virtual lecture. The lecture series highlights the work of high-profile scientists that speak truth to power and defend science. Read More

Science’s influence on pop culture is undeniable, and the reverse is equally important. Research led by Jay Clayton, the first literature professor to ever receive funding from the NIH, shows that films portray genetic science as risky far more often than television shows. Read More

Kenneth Catania, Stevenson Professor of Biological Sciences, has received the 2022 American Association for the Advancement of Science/Subaru SB&F Prize for Excellence in Science Books in the Young Adult Science Book category for "Great Adaptations: Star-Nosed Moles, Electric Eels and Other Tales of Evolution’s Mysteries Solved." Read More

Research conducted at Vanderbilt by Faith Rovenolt and Ann Tate has been published in a new study in The American Naturalist that models how parasites interact to affect their host’s behavior. The results of the research reinforce an understanding of the influence of disease in community dynamics. Read More

A team of astronomers has made the discovery of a lifetime that will help answer burning questions on the evolution of stars. The group is led by Keivan Stassun, Evolutionary Studies Initiative member and Stevenson Professor of Physics and Astronomy. Read More

Over the past decade, Larisa DeSantis, paleontologist and associate professor of biological sciences, has worked with a team of former Vanderbilt undergraduate and graduate students, postdoctoral scholars and experts from across the globe to show how species can be both generalized at the species level and specialized individually—a probable key to their success.
