Neil focused on tau protein which aggregates to form long fibers inside neurons in the brain. He worked on understanding the early structural mechanism of the tau aggregation pathway. Tau aggregation is known to be associated with several neurodegenerative diseases known as Tauopathies which also include Alzheimer’s disease. By using double electron electron resonance (DEER), Neil was able to look at conformational changes both before and after inducing aggregation. Through tracking and characterizing specific conformational intermediates, it could be possible to locate structurally distinct targets for the treatment of tau related diseases.
