  • 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.

  • 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

  • Field Work

    Many genes that organisms use to regulate their mutualists are also used to defend against parasites and pathogens. The shared genetic control of beneficial and harmful symbioses raises the intriguing possibility that susceptibility to infection is a pleiotropic cost of mutualism. Our goal is to understand how a genetic tradeoff between attracting mutualists and repelling parasites has shaped the genomic architecture of traits mediating species interactions, and how ongoing conflict influences adaptation. 

  • Courtship in Drosophila

    Various courtship songs produced by Drosophila species

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.
