• Post-doctoral Researcher at Exascale Computing Research Lab

  • Apr 2013 - Sep 2016

  • Implemented the Fast Multipole Method (FMM) for computing long-range electrostatic and polarization forces in the molecular dynamics program POLARIS(MD). • Used a hybrid software architecture that combines OpenMP and MPI to run on massively parallel supercomputers using thousands of cores. The force-field in POLARIS(MD) is notable for being completely parameterized from high-accuracy quantum computation and is not tuned to experimental results. Polarization is accounted for using the induced dipole method which can dynamically adapt to a changing electric field. Using this sophisticated force-field we are expanding our understanding of viral infection mechanisms, cell membrane interfaces, protein folding (including intrinsically disordered proteins), and a host of other biological functions at the molecular level. Possible applications include computer assisted drug development, but could extend further to nano technology and energy production. Show less
