  • 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.

  • Arabidopsis

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

  • Drosophila

    Drosophila are small flies, typically pale yellow to reddish brown to black, with red eyes. Many species, including the noted Hawaiian picture-wings, have distinct black patterns on the wings. The plumose (feathery) arista, bristling of the head and thorax, and wing venation are characters used to diagnose the family.

  • Telomeres

    Giant ‘polytene’ chromosomes (white) from a fruit fly with a fluorescent probe (red) that hybridizes to a telomere-restricted DNA repeat.

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.

Upcoming Events



Time and temperature matter in plant thermotolerance

Dr. Nick Kaplinsky, Swarthmore College
- | Leidy 109 and Zoom

Abstract: Plant responses to heat are finely tuned with even one degree differences affecting the kinetics of induced heat shock responses. Using a genetic approach, we identified a role for intron retention in…



The Panorama: Proteins, Pathogens, and Science in Peril

Dr. Brandon Ugbunu, Yale University
- | Fagin 116 and Zoom

In this seminar, I will discuss various projects in protein evolution and mathematical epidemiology that examine the forces the dictate disease dynamics. Lastly, I will discuss my work at the intersection between…
