What we do
We strive to characterize molecular interactions within and between proteins, including their substrates, antibodies, and small molecule compounds using structural and computational biology. We leverage our thorough understanding of these molecular interactions to develop clinically relevant solutions, including designing and optimizing inhibitors.
How we do it
We synergistically utilize experimental and computational techniques to gain fundamental insights into molecular recognition events involving protein-protein and protein-ligand interactions. Much of our work focuses on developing design strategies for drug candidates against resistant viruses, but we also apply this framework to other diseases such as cancer and Type I Diabetes.
Why we do it
Beyond our passion for fundamental molecular and structural biology, we are motivated by our goal of contributing to the development of new treatment options for various human diseases.

Ozen, A., Lin, K.H., Kurt Yilmaz, N., Schiffer, C.A. (2014) Proc. Natl. Acad. Sci.
While evolving high levels of resistance to protease inhibitors, HIV-1 accumulates mutations not only in the protease but also its substrates. In this work we revealed the molecular-level interplay between these two types of resistance mutations, and how co-evolution of the substrate restores the structure and dynamics of the complex to allow evolution of resistant viral variants.

Leveraging our knowledge of the intermolecular interaction between HCV NS3/4A protease and its natural substrates, we designed improved inhibitors that display better potency against clinically relevant resistant variants of the virus. These lessons are transferable to the design of potent and robust inhibitors against other dug targets.

Anti-idiotypic antibodies are those that bind to other antibodies with critical implications for response to infection and vaccination. In this work, structural modeling and analysis helped explain experimentally observed specificity and reactivity of the anti-idiotypic antibody G6, which binds to anti-influenza stem-directed broadly neutralizing antibodies.
