Biography

He is a computational scientist working for TechTrans International Inc as a consultant to Argonne National Laboratory (ANL), USA. His research directions align with the development and application of stable, robust, scalable, and high-order accurate spatio-temporal numerical methods for the simulation of multiphysics phenomena, primarily in the areas of nuclear engineering and climate science. He is also interested in simplifying various aspects of the scientific computational workflow i.e., adaptive unstructured mesh generation schemes for PDE solvers, consistent nonlinear solvers, data analysis, visualization, and sustainable scientific software implementations for high-performance computing architectures.

He previously held positions at ANL as a computational postdoctoral fellow and as a computational scientist until 2018, before moving to Toronto, Canada.
