Research interests

I study a class of proteins present on the surface of cells called G protein-coupled receptors (GPCRs). They are targets for approximately 34% of all clinical drugs and are implicated in several diseases. I work on developing new methodologies to determine their atomic-resolution structures and these provide high-resolution templates for novel drug development. 

Teaching Interests

In the past I have taught human anatomy and physiology, including human cadaver dissection, at Kansas State University. I share an interest in teaching biochemistry, molecular, cell and structural biology, genetics and microbiology.
