I am a Post Doctoral Scholar at the William G. Lowrie Department of Chemical and Biomolecular Engineering, The Ohio State University.
Post Doctoral research project:
(i) Coarse-grained molecular dynamics simulations to study how copolymers
with different types of liquid crystal moieties can be designed to exhibit complex deformation
behavior.
Doctoral research projects:
(i) Rheology predictions of entangled polymer melts from first principles, using atomistic simulations and a slip-link model theoretical framework.
(ii) Atomistic molecular dynamics simulations to study water transport in composite graphene nanochannels with a polymer matrix support.
