Dr. Bag is interested in studying and exploring the puzzling mechanism of protein/peptide aggregation and fibrillation which is one of the key reasons of many devastating neuro and non-neuro degenerative diseases. One example is Alzheimer’s disease and the amyloidosis of Aβ peptides behind this disease. Many other proteins and peptides are also involved in such protein fibrillation processes which pilot into other diseases. Mechanism of these processes is yet to be entirely understood. Our aim is to understand the mechanism and finding remedies of such diseases.
