Biography:

Dr. Congjian Wang is a postdoctoral nuclear engineer working in thermal science and safety analysis at INL. He is helping develop tools and methodologies for uncertainty quantification and validation for multi-physics fuel performance simulation.

While conducting postdoctoral research at Purdue University,
Dr. Wang developed new sensitivity analysis and uncertainty quantification techniques for depletion calculations and developed new data assimilation techniques.

He was a core contributor to the nuclear reactor analysis toolkits, “Insure,” “Crane,” “Poseidon” and “Alchemy.”
