"Research in the Roberts lab is generally focused on quantitative prediction, design, and control of the physical stability of proteins from the perspective of biopharmaceutical products based upon therapeutic proteins and polypeptides. We combine experiments, modeling, and molecular theory across biochemical engineering, applied biophysics, and pharmaceutical sciences to address a range of topics that include: protein misfolding and aggregation; protein-protein and protein-excipient interactions; proteins at interfaces; high-concentration behavior and stability; and protein engineering create improved product properties. Additional details on each of the topics is available at the Research Group link above."
