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.​​​"

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] .
