FACULTY
Biography
Dr. Saikat Roy did his postdoc from Weizmann Institute of Science, Israel. He completed his Mtech+PhD dual degree in chemical engineering from IIT Bombay in the year 2016. As a part of his PhD work, he studied the consolidation of colloidal gel via simulation and theory and proposed a model which does fairly well in predicting the salient features of the compressional rheology of gels. During his postdoctoral research, he studied the behaviour of frictional granular matter via simulation and theory. His research interests mainly lie in Granular Mechanics, Soft Condensed Matter and related Solid Mechanics, Jamming and Glass transition,Complex fluid Rheology.
