Summary of Scholarly Activities

    I have created (but no longer update) an integrated package of computer-based learning tools for teaching biochemistry of metabolism in a studio format. The Biochemistry of Metabolism web site includes lecture notes with diagrams and animations, interactive self-study quizzes, references to recent review articles, and instructions and data files for studio exercises. Some studio exercises use Chime to explore protein structure/function relationships. Others involve data analysis and/or problem solving. This project was supported by a Strategic Initiatives Grant from Rensselaer Polytechnic Institute, a grant from the National Science Foundation, Division of Undergraduate Education, and a grant from the Basic Biosciences Minigrants Foundation.

    I previously carried out research characterizing the kinetics and reagent-sensitivity of K+ and Mg++ transport into mitochondria, using radioisotope tracers. While attempting to purify ion channels from mitochondrial membranes, patch clamping and fluorescent probes were used to detect and characterize activities of reconstituted preparations.
