Research Description

My goal is to design, develop, fabricate and support world class microscopy systems for research in molecular physiology. Our research demands high sensitivity with fast temporal and precise spatial resolution. These systems include integrated Laser Optical Tweezers with dual color Total Internal Reflection Microscopy (TIRFM) along with single molecule detection, manipulation and tracking capabilities. Mechanical measurements of pico-newton force, nanometer displacement, and pico-newtons/ nanometer stiffness are used to address questions in single molecules. These techniques are applied to protein ensembles, intercellular dynamics, and molecular protein- protein interactions. High speed fluorescent imaging of single molecule dynamics are possible using state of the art ICCD cameras with TIR and far field illumination. Recent initiatives include high speed 3D tracking, STORM, and PALM Super Resolution microscopy. Myosin, Kinesin, C-Protein, Actin, Microtubules and other Cytoskeletal proteins are studied with our techniques.
