Research Interest(s):
I work with the aspects of plants that nobody can see with a casual glance! My research program revolves around two topics involving post-translational processing in plant proteins. My first project was initiated during my Postdoctoral work at Iowa State University on the elucidation of the post-translational proteolytic processing mechanism that facilitates the removal of internal peptide sequences from a translated polypeptide. My work will focus on identifying the components involved in this processing in higher plants in addition to identifying endogenous requirements for this processing system. My second project was initiated during my graduate studies at Washington State University and focuses on the role of post-translational phosphorylation in the regulation of seed transition from a dormant to germinable state. This work involves understanding the signal transduction pathways that utilize phosphorelay systems in response to environmental signals such as hydration. It doesn't matter so much that the plant has germinated, but that the plant has received and interpreted a command to germinate. Participation in these research programs by students is always encouraged as they provide excellent opportunities to develop critical thinking skills and research skills, as well as the chance to experience the awesome work environment that is a laboratory!
