Biography

After receiving his B.S. degree in engineering physics from Tsinghua University at Beijing, China in 1999, Dr. Ji went on to earn a M.S. 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 M.S. 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 Nuclear Computing and Multi-Physics (NuCoMP) Research Group, focusing on the development of advanced computation methodologies that are applied to the areas of nuclear energy, medical physics, nuclear criticality safety, and space. 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 modeling of coupled granular flow and fluid flow in pebble-bed reactors, new algorithms on heterogeneous parallel CPU-GPU-Coprocessor architectures to accelerate Monte Carlo simulations, and cross-cutting modeling techniques to understand radiation effects on microelectronic devices. Dr. Ji has been leading research projects funded by Department of Energy (DOE), National Aeronautics and Space Administration (NASA), National Institute of Health (NIH), and Nuclear Regulatory Commission (NRC). He has authored over 120 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 energy system design, advanced fuel cycle system analysis, and radiation charaterization and effect evaluations in bio-systems and micro-electronic devices.

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

  • Reduced-order modeling for radiation transport computation and computational fluid dynamics
  • Experimental benchmark development for multiphysics computation validation
  • Coupled granular flow and fluid flow simulation based on multi-physics models
