Wei Ji

Associate Professor, Mechanical Aerospace and Nuclear Engineering

After receiving his BS degree in engineering physics from Tsinghua University at Beijing, China in 1999, Dr. Ji went on to earn a MS in the area of nuclear technology and its application from the same institution in 2002. He then came to the U.S. to enter the Ph.D. program in Nuclear Engineering at the University of Michigan, earning his MS in 2004 and Ph.D. in 2007. During this period, Dr. Ji had participated in several DOE funded projects on the research, development and demonstration of Very-high Temperature Gas-cooled Reactors, one of the promising candidates for Next Generation Nuclear Power Plant. He had been a research specialist at General Atomics and Argonne National Laboratory in 2005, working on the advanced fuel cycle designs using deep-burn gas cooled reactors for the transmutation of used fuel. After receiving his Ph.D. at Michigan, Dr. Ji joined RPI as an Assistant Professor in January 2008. He was promoted to Associate Professor with Tenure in July 2015. At RPI, Dr. Ji leads the Rensselaer Nuclear Engineering Advanced Modeling and Simulation Group (R-NEAMS), focusing on the development of advanced computation methodologies that are applied to the areas of nuclear energy, medical physics, and nuclear criticality safety. These methods include Monte Carlo modeling of radiation transport in stochastic media, on-the-fly sampling of thermal inelastic scattering reaction at any temperature based on S(alpha, beta) nuclear data, multi-physics models for coupled granular flow and fluid flow simulations in pebble-bed reactors, and new algorithms on heterogeneous parallel CPU-GPU-Coprocessor architectures to accelerate Monte Carlo simulations. Dr. Ji has been leading or co-leading research projects funded by Nuclear Regulatory Commission, Department of Energy, and National Institute of Health. He has authored over seventy peer-reviewed publications and served on the program and organizing committees of various national and international professional societies, workshops and conferences.
