While studying as an undergraduate, developed a variant of a parallel molecular dynamics code to model swarm robotics control. Modeled robots as gas-like particles with simple behavior and sensor capabilities so collective behavior could quickly search an area for targets such as hazardous waste or land-mines. Implemented in C using MPI for parallelization and used some OpenGL for visualization.
