Instructor bio

Prof. Madivala G. Basavaraj

IIT Madras

Associate Professor, Department of Chemical Engineering, Indian Institute of Technology- Madras. Before joining IIT-Madras in February 2011, I spent 3 months as visiting fellow at KULeuven (Belgium) in Prof.Jan Vermants group. I was a postdoctoral researcher with Prof. Norman J. Wagner at the University of Delaware (USA). I studied chemical engineering at SIT, Tumkur (Bangalore University), and received my M.S (Research) from IISc, Bangalore, by working on the determination of local dispersion coefficient and local holdup in a packed bed using X-rays. My PhD in chemical engineering is from KULeuven, Belgium (Prof. Jan Vermant). My PhD thesis was on - Tailoring colloidal gel rheology in bulk and at interfaces: Exploiting shape and surface chemistry effects.
