Assistant Professor of Biochemistry & Molecular Biology
Virus-host interactions involved in the pathogenesis of alphaviruses and flaviviruses. Analysis of virus induced structures and cytoskeletal modifications in mammalian host and insect vector using high-resolution live cell imaging and electron microscopy. Viral determinants of neurotropism, encephalitis, transmission and persistence in BSL-3 pathogens.
Associate Professor of Biochemistry & Molecular Biology, Co-Director, Center for Malaria Research
Our laboratory couples molecular parasitology and structural biology to study the malaria parasite (Plasmodium spp.).
Professor of Biochemistry and Molecular Biology
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.
Associate Professor of Biochemistry and Molecular Biology
The mechanisms by which bacteria sense and respond to the environment, as well as how these signaling proteins/pathways affect competition, host colonization, and pathogenesis.
