  • 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.

  • ERK1/2 signaling pathway

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

  • Porphyrogenes peterwegii

     Pupa of the butterfly Porphyrogenes peterwegii "peering" out of its leafy nest with false eyes, which in turn mimic the eyes of a snake, thereby protecting the pupa from small feather-brained  birds.

  • 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.
