I am a postdoctoral scholar in the Center for Computational Sciences and Engineering (CCSE) in the Computational Research Division of the Computing Sciences Directorate at the Lawrence Berkeley National Laboratory. I am interested in applying novel (and large-scale) simulation techiniques to broad range of non-equilibrium complex systems. Currently, I am using AMReX and MFIX-Exa to investigate the collective dynamics of hydrodynamically and chemically interacting microswimmers. As well as exploring how coarse-graining techniques can be used to simulate multi-phase granular flows at extremely large scales.
