  • ERK1/2 signaling pathway

     ERK1/2 signaling pathway regulates exocytosis and tumor invasion through phosphorylation of the exocyst complex.

  • 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.

  • 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.

  • 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.

Upcoming Events



The epic evolutionary journey of an iconic urban animal, the brown rat (Rattus norvegicus): from the grasslands of Asia to the streets of New York City

Dr. Jason Munshi-South, Drexel University
- | Leidy 109 and Zoom

Abstract: A unique assemblage of native and nonnative rodents inhabit cities but differ in their occupancy of "green" and "gray" infrastructure. They also vary in their ability to disperse through heterogeneous…



Virus-like intercellular communication in the nervous system

Dr. Jason D. Shepherd, University of Utah
- | Leidy 109 and Zoom

Abstract: The immediate early gene Arc is critical for long-term associative memory consolidation in mammals. We discovered that the Arc gene evolved from an ancient retroviral element and has retained viral-…



Deciphering Neural Circuits for Vocal Communication: Insights from the Singing Mice.

Dr. Arkarup Banerjee, Cold Spring Harbor
- | Leidy 109 and Zoom

Abstract: My long-standing interest is to understand how circuits of interacting neurons give rise to natural, adaptive behaviors. Using vocal communication behavior across rodent species, my lab at CSHL pursues two…
