Postdoctoral Researcher, Computational Research Division
Current Affiliation and Research Interests
I am a postdoctoral researcher at the Center for Computational Sciences and Engineering (CCSE) in the Applied Mathematics Department of the Computational Research Division, a part of the Computing Sciences Area at the Lawrence Berkeley National Laboratory.
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 theory and numerical methods towards predicting the structure and dynamics of complex fluids, soft materials and granular materials, especially in far-from-equilibrium conditions.
In the Multiscale Modeling and Stochastic Systems (MuMSS) group at CCSE, I am currently developing numerical simulations of stochastic systems that describe complex fluids (such as electrolytes) at the mesoscale.
Previously, I worked as a postdoctoral appointee at the Center for Integrated Nanotechnologies in Sandia National Laboratories, where I conducted theoretical and numerical investigations of phase transitions in soft and granular materials, and also developed and conducted large-scale simulations of mesostructure and electrochemical transport in lithium-ion battery electrodes.
I received my PhD in Mechanical Engineering from Purdue University in the summer of 2017, where I studied mechanics, rheology and transport in granular materials through numerical simulations.
