Asif's main focus is method development and application of solid-state dynamic nuclear polarization (DNP) enhanced NMR to study biosolids, in particular aggregation intermediates of Tau proteins. In addition to this, understanding electron spin dynamics under non-continuous microwave irradiation condition is another major goal in the pursuit of improving DNP efficiency in power limited and faster magic-angle spinning frequency regime.
