Personal Statement:To develop the most advanced high-resolution analysis software for analytical ultracentrifugation experiments.

Research Interest:

Our main project involves the development of the UltraScan data analysis software package ( This software is used for modeling of hydrodynamic and thermodynamic properties of biological and synthetic macromolecules, and interactions and thermodynamic characteristics of macromolecular assemblies. Areas of research involve advanced numerical analysis, optimization, high-performance network computing and cluster computing. Currently we are working on the development of software for the interpretation of multiwavelength sedimentation velocity experiments, and on spectral decomposition of analytical ultracentrifugation experiments. We are also investigating rigid body modeling approaches for predicting hydrodynamic properties of macromolecules and for the interpretation of small angle X-ray scattering data.
