Other Teaching and Advising

I advise one third of our fourth year Biochemistry majors class. I taught BCHM 1014, Introduction to Biochemistry, to first year students, and was awarded support for this course by the First Year Experience program. For this course I started a peer mentoring program with undergraduates. At the graduate level, I helped develop GRAD 5984, Graduate Professional Development in the Life Sciences.

Program Focus

The focus of my research is on the molecular pathways that plants use to respond to the environment, an area important for developing strategies to increase crop yield in stressful or nutrient-poor soil conditions. My lab works as part of an NSF-funded collaborative project on new inositol signaling molecules called PPx-InsPs. Along with my collaborators at North Carolina State University and the USDA, we are examining PPx-InsPs as critical players in metabolism and stress. This work also has implications for understanding basic mechanisms to control phosphate pollution in watersheds, an important problem in Virginia.

A second research project is a collaboration with Dr. Ryan Senger (BSE). This project’s goals are to develop a genome-scale model for Arabidopsis which can predict genes that can be used to increase cellulose content of plants. In a synergistic project, we are examining genes involved in energy signaling in plants. Along with Dr. Brian Phillipy of North Carolina State University we are translating our work on energy-signaling and senescence to cotton, an economically important crop plant. Group presented five posters at local, regional and international meetings this year.

My lab has significant science outreach efforts with continuing participation in the Partnership for Research and Education using Plants (PREP), Kid’s Tech University (KTU), and a plant stress exercise for local fourth-graders. I along with my graduate students, visit high school classrooms in Roanoke and Fairfax county. A new outreach project with Blacksburg High School will help build connections between scientists, teachers and high school teachers and classrooms.
