Ishan Srivastava

I am an Applied Math postdoctoral scholar in the group of John Bell at the Center for Computational Science and Engineering in Lawrence Berkeley National Lab, where I am developing numerical simulations of stochastic systems that describe complex fluids at the mesoscale. Previously, I was a postdoctoral scholar in the Center for Integrated Nanotechnologies at Sandia National Labs, where I worked with Gary Grest on theoretical and computational investigations of soft and granular materials, and with Scott Roberts on mesoscale investigations of lithium-ion battery electrodes. I received my PhD in Mechanical Engineering from Purdue University in summer of 2017, where I was advised by Prof. Tim Fisher at the Birck Nanotechnology Center.

My current research interests lie at the intersection of soft matter, statistical mechanics and continuum mechanics (solid and fluid mechanics). I am particularly interested in developing theories and computational techniques towards predicting the structure and dynamics of complex fluids, soft materials and granular materials, especially in non-equilibrium conditions. Beyond fundamental explorations, my research is often motivated by specific engineering applications such as optimizing electrochemical transport in lithium-ion batteries.
