Biography

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, National Institute of Health, and National Aeronautics and Space Administration. He has authored over ninety peer-reviewed publications and served on the program and organizing committees of various national and international professional societies, workshops and conferences.

Research Summary

In the past years, Dr. Ji performed research on the advanced modeling and simulation for Next Generation Nuclear Reactors design, Advanced Fuel Cycle Systems analysis, current commercial Light Water Reactor fleet sustainability, and radiation charaterization and effect evaluations.

Dr. Ji's research interests are focusing on the following aspects:

  • Coupled granular flow and fluid flow simulation based on multi-physics models
  • On-the-fly sampling method for thermal neutron scattering in Monte Carlo simulations
  • Radiation transport simulation in 3-D stochastic media
  • Monte Carlo simulation on hybrid computing architectures for medical physics and nuclear energy applications
  • Nuclear energy system design for space applications
  • Radiation effect on silicon carbide based power devices for space applications
  • Coupling Neutron transport with molecular dynamics to predict radiation induced material degradation
