Brief bio: I am interested in understanding the signal transduction events in plants during their abiotic stress interactions. During my doctoral program, my research focused on understanding how plants coordinate their stomatal responses to various abiotic stresses including light stress responses. During this time, we found that different leaves within the canopy of Arabidopsis thaliana coordinated stomatal closure responses, to changes in light intensity by sending and receiving rapid systemic signals. These signals are mediated by a rapid auto-propagating wave of reactive oxygen species (ROS) production that depends on the function of respiratory burst oxidase homologs (RBOHs; NADPH oxidases). The current study is a part of my postdoctoral research, that highlights the role of Phytochrome B in regulating local and systemic stomatal aperture closure responses to light stress. After my tenure at the University of Missouri, I will be joining as a postdoctoral associate in the plant systems biology group at the Oak Ridge National Laboratory.
