Ishan Srivastava
Ishan Srivastava is a Research Scientist in the Applied Mathematics Department within the Computing Sciences Area at Lawrence Berkeley National Laboratory, and affiliated with the Center for Computational Sciences and Engineering (CCSE).
His research aims to apply theory and simulation to understand the structure and dynamics of highly-deforming soft materials. A particular area of interest is the physics of granular materials and complex fluids, which are of enormous technological and natural importance. His research uses a variety of computational methods such as molecular dynamics, discrete element method, and continuum fluid and solid modeling. Such a multiscale approach to simulate these materials allows the identification of particle scale processes that govern macroscale material behavior. His research aims to develop novel computational methods in particle-scale modeling to predict microstructure-aware constitutive relationships which eventually inform the continuum modeling of these materials in practical scenarios. Some motivating applications for his research include advanced manufacturing of energy materials such as battery electrodes, and industrial handling and processing of powders and suspensions, especially in manufacturing applications.
Background
Ishan received his PhD in Mechanical Engineering from Purdue University in the summer of 2017 under the supervision of Prof. Tim Fisher, where he investigated the mechanics, rheology and transport in granular materials consisting of nonspherical particles (here is a link to the dissertation). After graduate studies, he conducted postdoctoral research with Gary Grest at Sandia National Laboratories, where he developed constitutive models of dense granular flows and high-pressure deformation of polymer nanocomposites using molecular dynamics and discrete element methods. Subsequently, he was a postdoctoral scholar with John Bell at Lawrence Berkeley National Laboratory, where he investigated the fluctuating hydrodynamics of nonequilibrium fluids and mesoscale electrokinetic transport in electrolytes through continuum solutions of the governing stochastic partial differential equations.
