B.Tech. Indian Institute of Technology Kanpur (2009)
Biography
Piyush comes from India where he did his Bachelors in Mechanical Engineering from Indian Institute of Technology Kanpur. After working for two years in industry, he came to UIUC and did his Maters working on theoretical and experimental studies of energy transport in nano-structures. He joined the Ewoldt Research Group in 2013 for his PhD.
Research Interests
Piyush has interests in polymer physics, nonlinear rheology and inverse problems. He has been working on the nonlinear oscillatory shear rheology of polymer melts; developing a novel, faster and material economical technique during of the course of the project. Other projects include inverse problems in rheology, looking at uncertainty quantification of data and model parameter estimates, and reducing subjectivities in the process of calibration of physically meaningful model parameters.
