The ultimate goal of my research is to understand viruses and viral diseases for the betterment of agriculture. Our research involves a number of important viruses that infect plants, which include Grapevine rupestris stem pitting-associated virus (GRSPaV), a ubiquitous and important pathogen of grapes worldwide. Current research directions include: Processing and subcellular localization of polyproteins; structure and cellular localization of viral replication complexes; evolution and bio-informatics of grapevine viruses; development of virus-induced gene-silencing vectors ; and, development and application of technologies for the diagnosis of grapevine viruses.Learn More
My lab focuses on two main axes of research:
1) Unfolded Protein Response and Human Diseases: We study proteins that play key roles in animal stress responses, specifically the Unfolded Protein Response (UPR), which has been linked to animal development, cell differentiation, as well as a variety of human diseases such as Alzheimer’s, diabetes, cancer and viral infection.
2) Molecular Mechanisms of Aging: We are working to establish planarians as a new aging model to test the hypothesis that longevity requires multiplex resistance to stress. We hope to identify genes or alleles that confer such multiplex stress resistance and/or promote longevity.
My research focuses on three main areas of plant cell biology:
1) Characterization of enzymes involved in seed oil biosynthesis.
2) Understanding various aspects of the biogenesis of peroxisomes, including how membrane proteins are targeted to this organelle, and what role the endoplasmic reticulum (ER) serves in the formation of peroxisomes.
3) Identification and characterization of a unique class of integral membrane proteins known as "Tail-Anchored" (TA) proteins.
