  • Sea Anemone

  • Larix siberica

    Siberian Larch, taken at our field site near Lake Khovsgol in north-central Mongolia.  We are analyzing tree-ring width and stable isotopes of the tree rings to reconstruct climate, and Larch responses to climate change, over the past century as the temperature in Mongolia has risen.  

  • Consequences of HD-ZIPIII dysregulation

    How do organisms create such complex and beautiful shapes? And how do they do it so reproducibly? Plants are an excellent system to study these questions. For instance, the HD-ZIPIII family of transcription factors are >700 million years old and regulate nearly all aspects of plant development. Consequences of HD-ZIPIII dysregulation on plant morphology are severe (pictured here). Understanding how HD-ZIPIII proteins work is a central theme of the lab.

  • Bacterial Respiratory Complex

    Structural model of a bacterial respiratory complex III: remember that when you respire, your complex III perspires to produce your body's energy.

  • Arabidopsis

    Wild-type and transgenic Arabidopsis plants expressing miR156, a microRNA that promotes juvenility and increases the rate of leaf initiation

Biology is fundamental to our changing world. The 21st century challenge for our students, our scholars, and the greater society is to understand our place in this changing world and to create fundamental knowledge for informed policies, economies, and social structure.

Demography and Infectious Disease

Jessica Metcalf, Princeton University
- | DRL 3C8 and via Zoom

Mathematical models, as Bob May wrote, "force[s] clarity and precision upon conjecture, thus enabling meaningful comparison between the consequences of basic assumptions and the empirical facts”.  Mathematical…



Leveraging Evolutionary Mismatches to Study Gene-by-Environment Interactions

Dr. Julien Ayroles, Princeton
- | Levin Building Auditorium (Tedori Family Auditorium)

Many of our most onerous health burdens today are driven by complex and poorly understood interactions between a person’s genetic makeup and their environment. In other words, genetic variation may predispose…



The evolution of sleep loss in Mexican cavefish

Dr. Alex Keene, Texas A&M University
- | Levin Building Auditorium (Tedori Family Auditorium)

Abstract: Sleep is nearly ubiquitous throughout the animal kingdom, yet its duration and timing varies dramatically between species. We have developed the Mexican tetra, Astyanax…
