Ratul Das, Ph.D.

Postdoctoral Fellows


Research Interests

My research focuses on solid-liquid interactions and processes associated with friction, lubrication, soft matter physics, and surface characterization. It is highly multidisciplinary and spans applications ranging from bio-compatibility, through solid-liquid tribology to enhanced oil recovery. I also have interests in polymer rheology, process technology and development of coatings for heat transfer equipments which comes from my industrial background.
