    Current Research

    The research in my laboratory is interdisciplinary and focuses on understanding structure, dynamics and function of complex macromolecular assemblies, biological tissues and inorganic materials in the solid state. The main experimental tool is NMR spectroscopy combined with computational quantum-mechanical and biophysical methods. Biomolecular solid-state NMR spectroscopy is an integral biophysics and structural biology tool due to its unique capability to yield atomic-level information in insoluble macroscopically disordered systems, such as biological assemblies, membrane proteins, and fibrils. Of particular interest to us are systems where solid-state NMR methods provide unique (and often the only) insight into structure and dynamics: i) HIV-1 capsid protein assemblies whose function is integral in the virus pathogenicity; ii) physiologically important microtubule/cargo protein assemblies whose malfunction is associated with multiple diseases; iii) biotechnologically important vanadium haloperoxidases; iv) intervertebral disc tissues whose aging and damage cause the prevalent degenerative disc disease; v) technologically relevant oxoanionic solids. Understanding structure, dynamics and function of these complex systems is critical for design of novel therapeutic strategies and diagnostic methods. We combine fundamental investigations in physical chemistry, biophysics, and structural biology with applied biomedical research seeking to develop novel magnetic-resonance-based diagnostic methods. Much of our research involves development of new solid-state NMR methods. We employ rigorous computational methods, at the level of molecular dynamics simulations and quantum chemical (Density Functional Theory) calculations, to gain comprehensive insight into the structure and dynamics of biological and inorganic systems and connect these to function.
