Biography

Professor Ahn teaches undergraduate and graduate courses in radioactive waste management and nuclear fuel cycle. The courses cover various aspects of radioactive waste management, including high-level radioactive waste disposal into deep geologic formations, the nuclear fuel cycle, and the environmental impact of nuclear power utilization. His research interests involve mathematical analyses of radionuclide transport in heterogeneous geologic formations and radionuclide release from man-made waste disposal systems, integrating these into an overall performance assessment model, and analyzing the nature of uncertainty incorporated in long-term assessments for radioactive waste disposal. He has been actively conducting research also in the fields of nuclear power utilization in Asia-Pacific region and Science-Technology-Society (STS) interaction in the back-end of fuel cycle.
