Daniel Schwen Staff Scientist Research Areas:
Mesoscale modeling and simulation Biography:
Daniel Schwen is a staff scientist in the Fuel Modeling and Simulation Department. His work centers on computational materials science with a focus on fission gas release modeling. He earned a Ph.D in Physics from the University of Göttingen, German in 2007. Daniel is a member of the Materials Research Society of North America as well as a member of the German Physical Society. He is the lead developer of the mesoscale NEAMS-funded MARMOT tool, the MyTRIM binary collision Monte Carlo code, and the MARMOT-MyTRIM coupling application Magpie. He has implemented core multiphase modeling and mechanics coupling functionality into MARMOT and designed novel rapid model development capabilities. His expertise is in the area of multiscale modeling, with a focus on using mesoscale modeling and simulation tools to bridge from the atomistic to the macroscale. Dr. Schwen has experience in modelling materials under irradiation and thermodynamic modeling. Additionally, he is interested in geospatial data processing (algorithms and data structures) and contributes as a volunteer to Wikipedia and Wikimedia projects.
