Research Interests:

Molecular motors – Molecular mechanisms associated with muscle contractility, motility, and molecular motors (myosin-actin, kinesin-microtubule, DNA motors -DNA). The techniques employed include optical microscopy and spectroscopy, light scattering (dynamic and Raman), ellipsometry, optical trapping and many aspects of fluorescence microscopy (TIRF, confocal, FCS, FRET, Antibunching).

Biomineralization and biomimetics – This area covers the topics of antifreeze protein – ice as well as amino acid – calcite interfaces. The techniques used are scanning force microscopy, nuclear magnetic resonance (solution and solid state), surface-sensitive nonlinear optical spectroscopy, and molecular dynamics simulation.

Cellular signaling mechanisms – This area includes protein aggregation on membranes for the purpose of intra- and intercellular signaling for functions. We use optical and scanning microscopy methods to investigate the dynamics of organization structures on cell membranes.
