I investigated conformational diversity of Abeta oligomers with immunological and spectroscopic (fluorescence, FTIR, CD, EPR) methods and collaborated with other labs to obtain detailed structural information about them with 2D-FTIR and Raman spectroscopy. Developed a high-throughput ELISA-based immunoassay for screening of inhibitors of Abeta oligomerization.Supervised research assistants.

Played an important role in the first detailed study of the structure of prion fibrils and the mechanism of prion replication primarily using FTIR, EM and LC-MS. Showed that methionine oxidation and GPI anchor attachment interfere with prion aggregation. Developed a high-throughput screen for inhibitors of prion propagation, patent application based on this research has been submitted.
