Biophysics and Proteome Level Investigations of the Functions of Intrinsically Disordered Proteins

Our research is focused on the study of intrinsically disordered proteins. We develop and use state-of-the-art computational methods and combine these with experimental techniques to understand how information encoded in amino acid sequences of intrinsically disordered proteins governs their molecular function, contributes to organization of protein interaction networks, controls cellular decisions, and modulates the mechanisms of protein self-assembly.


Relevant diseases: Huntington's disease; Alzheimer's Disease; Prions; Cancers
