Our group has been particularly active in the development of quantitative hydrodynamic methods using sedimentation velocity analytical ultracentrifugation in conjunction with mathematical modeling of reaction/diffusion/sedimentation processes. We have recently embarked on the development of novel fluorescence detection approaches, which allow unprecedented sensitivity and resolution. We are also pursuing other techniques, including optical biosensing, isothermal titration calorimetry and global multi-method modeling approaches. We are dedicated to the dissemination of methodology, and have implemented our computational analysis methods in widely used software.

We are involved in several collaborative applications in various fields including immunological protein complexes, viral proteins, membrane receptor complexes, and eye lens crystallins.

Since the beginning of the COVID19 pandemic we have focused on the study of SARS-CoV-2 nucleocapsid protein, its assembly properties, structural features, and mutational landscape.
