In the Department of Biological Sciences, challenging science courses are just one part of a holistic approach to learning. Our curriculum integrates traditional study with individual mentorship in the lab and service learning and sustainable projects in the community, for a truly interdisciplinary experience.



"Perhaps the most exciting part of our work is the immediacy of it all. Never before has there been a greater need to understand wetlands ecosystems, as it might soon be too late.​​​"

Adapting to a Different Kind of Fall Semester

From remote learning to virtual club meetings, Columbian College students are approaching an unprecedented semester with optimism, determination and a commitment to making the most of new experiences. Biology students like Liam Searcy and Eugenie Pflieger share their stories of how they are approaching the challenges that COVID-19 brings.

Getting Creative: Biology Student Continues Research From Home

Rising senior biology major Alison Pagalilauan was engrossed in her research on oanalyzing meta-genomic data from steam vent samples collected in Hawaii’s Kilauea East Rift Zone when the COVID-19 pandemic shut down campus. Since then, Pagalilauan has used an online interface to continue her research from her home in New Jersey.

New Study Reveals How Wood Decay Drives Carbon Cycle

Through a combination of lab and field experiments, Associate Professor of Biology Amy Zanne and a team of researchers have developed a better understanding of the factors accounting for different wood decomposition rates among fungi. Their findings reveal how deciphering fungal trait variation can improve the predictive ability of early and mid-stage wood decay, a critical driver of the global carbon cycle.

Biology Alumni on the COVID Frontlines: Two New York Physicians Fight On

As the coronavirus turned New York hospitals into crisis zones, Doctors Luke Fey, BS ’13, and Alexandra Cummings, BS ’14, put themselves in harm’s way to confront a global medical emergency. “We’ve rallied together to fight the virus,” said Cummings, a pediatric resident at Cohen Children's Medical Center. “This is something we’ll remember forever and — cross your fingers — never face again.”

Pollinators Find a Home at GW

Students are studying what kind of insects spend their days feeding off Foggy Bottom flowers to better understand how to support the local ecosystem. The CCAS research team aims to identify pollinators, such as this wasp, that frequent flower beds on the Foggy Bottom campus.

The Caterpillar’s Role in Ecological Systems

Professor of Biology John Lill and his researchers collect roughly 3,000 caterpillars each summer to study the relationship between the herbivore diet and survival. Caterpillars are susceptible to parasitoid insects like bees and wasps, and their place in the ecological structure can affect much larger organisms like the nearly wiped-out American chestnut tree[KB1] .
