Position: Graduate student

Degrees:

• Ph.D. (2001) Plant Biology, North Carolina State University Department of Plant Biology, Raleigh, NC
  Thesis: Molecular and biochemical characterization of plant phosphatidylinositol 4-kinases. Two isoforms of PtdIns 4-kinases, AtPI4Kalpha and AtPI4Kß, were isolated from Arabidopsis thaliana. AtPI4Kalpha was characterized for its regulation by polyphosphoinositides and its potential role as a cytoskeleton-associated protein. Functional characterization was initiated by isolating an AtPI4Kalpha knockout in Arabidopsis.
• M.S. (1995) Nutrition Science Program, Purdue University, West Lafayette, IN
  Thesis: Isolation and characterization of a retinol-inhibited 55 kDa GTPase of rat liver transitional endoplasmic reticulum.
• B.S. (1993) Nutrition Science Program, Purdue University, West Lafayette, IN

Projects:

• Molecular and biochemical characterization of Arabidopsis thaliana PI 4-kinase isoforms
• Regulation of Arabidopsis thaliana PI 4-kinase activity and/or localization by its Pleckstrin Homology (PH) domain
• Identification and characterization of tDNA insertion mutants of Arabidopsis PI 4-kinase
