Program Focus

The major theme of research in our laboratory focuses on protein-ligand interactions, protein misfolding and amyloid diseases and discovery and mechanisms of small molecule inhibitors (including natural compounds). We use interdisciplinary approaches including biochemistry, biophysics/structural biology, chemistry, molecular and cell biology, and in vivo animal studies with a variety of techniques such as high throughput screening, protein and inhibitor design. Systems of studies focus on applications to diabetes, obesity, and neurodegenerative (Alzheimer’s disease) problems.

Currently our lab is supported by grants from the Commonwealth Health Research Board (CHRB), Diabetes Action Research and Education Foundation, and Alzheimer’s and Related Diseases Research Award Fund (Virginia Center on Aging). We have several projects under development (see below) and a number of national grants are pending. We welcome highly motivated young scientists for stimulating and productive collaboration and training.

Our lab is an active member of Biochemistry graduate program (home program), Virginia Tech Center for Drug Discovery (VTCDD), and Translational Obesity Research Interdisciplinary Graduate Education Program, Translational Biology, Medicine, and Health (TBMH), and newly established School of Neuroscience.

Current Projects

  1. Discovery and mechanisms of small molecule inhibitors against protein amyloid diseases (amylin and tau)
  2. Structure, function, and mechanistic studies of a newly discovered exercise hormone, irisin, that fights obesity and diabetes.
