Interests and Relevant Experience
Dr. Kuprat is an expert at computational geometry, mesh generation, and the solution of partial
differential equations using finite elements. His current interests include generation of optimized meshes
for computational fluid dynamics simulations on human and animal airway and cardiovascular
geometries, efficient schemes for conservatively mapping quantities in multiphysics simulations, and
moving finite element methods for materials microstructure modeling. Dr. Kuprat was a primary
developer of LaGriT (Los Alamos Grid Toolbox) at Los Alamos between 1994 and 2005. He continued
development on a PNNL version of this code (called LaGriT-PNNL), incorporating novel scale-invariant
meshing algorithms. LaGriT has been widely used in multimaterial geological meshing (including Yucca
Mountain studies), while LaGriT-PNNL has been recently used for biomedical CFD mesh generation and
materials science (solidification and heatflow) applications.
