Structural and functional basis of cellulose synthesis. Using Physcomitrella patens and other organisms as model systems, we are learning how plants make cellulose for building new cell wall. The studies use methods of molecular biology and cryoEM to characterize the enzyme as a monomer, and when it assembles into its larger 'Cellulose Synthase Complex '(CSC for short). The aim is to understand cellulose synthesis to explain fundamentals of cell wall biology in plants, and to enable manipulation of its synthesis for applications in fields of bioenergy and materials.

Professor of Biology
I am a Biomathematican and very recently moved to Penn State from Georgia Tech (I also had appointments at Emory in Public Health and PBEE). Bacteria and their viruses (phages) provide a way to study ecological and evolutionary processes in real time under the well-controlled laboratory conditions. Many of the questions that our group studies lie at the intersection of fundamental science and improving human and animal health. We develop new approaches to mathematical modeling to better understand the role of the physical structure in how bacteria grow and evolve. To complement this computational work, we work closely with microbiologists, biochemists, virologists, physicians, veterinarians, etc. and combine mathematical models with experiments. In recent years I have taught courses in virus dynamics, population genetics, dynamics and bifurcations, advanced linear algebra, and stochastic processes.
