Research in my lab in collaboration with Dr. Imara Perera focused on the role of inositol phospholipids in regulating plant sensing and response to environmental stimuli including osmotic stress and gravity. We took a combinatorial approach that includes biochemistry, cell biology, and molecular biology to characterize the enzymes involved in inositol lipid biosynthesis, to study their subcellular distribution and to genetically alter the flux through the PI signaling pathway. In addition, in collaboration with Dr. Amy Grunden, we took a molecular genetics approach to reduce the presence or reactive oxygen species in plants by expressing genes from Pyrococcus furiosus.
