Outstanding Nuclear Engineers


Han Gyu Joo

Han Gyu Joo

Ph.D 1996
President, Korea Atomic Energy Research Institute (KAERI)

Dr. Han Gyu Joo has been serving as the President of Korea Atomic Energy Research Institute (KAERI) since December last year. He is on leave from his professorship at Seoul National University where he had served as a Professor of Nuclear Engineering for 18 years. He got his Ph.D. in Nuclear Engineering from Purdue in 1996. Before being admitted to the School of Nuclear Engineering in 1993, he worked on the nuclear design of the YGN 3&4 nuclear power plants in Korea for 7 years as a KAERI engineer. For this work, he was trained at Combustion Engineering, Inc. for 2 years from 1986 during which he learned how to use various neutronics codes. During his 4 and half year stay at Purdue including the postdoc period, he studied the methods needed for developing codes and he wrote the initial version of the PARCS (Purdue Advanced Reactor Core Simulator) code which is now being used worldwide through the NRC framework. After returning to KAERI, he led the development of a Numerical Nuclear Reactor based on the DeCART direct whole core calculation code. After moving to SNU in 2004, he broadened his expertise in computational reactor physics and developed many neutronics codes as well as a core thermal hydraulics code with his students. He was inducted as a Fellow of the American Nuclear Society in 2015. He is also an inducted member of the National Academy of Engineering of Korea.

During Webster’s tenure, Weapons programs have consistently made significant contributions to LANL and NNSA missions. Webster is responsible for the strategic leadership, management, planning, and execution of the nuclear weapons program at Los Alamos to meet the primary mission of ensuring the safety, reliability, and performance of the nation’s nuclear deterrent.
Webster provides the Laboratory’s primary interface for the nuclear weapons program and plans and coordinates interactions with key customers in the NNSA, Department of Energy, and the Department of Defense.
He is also responsible for the development and implementation of institutional plans and
programs that meet or exceed LANL’s contractual requirements and performance measures, as well as for ensuring compliance with all state and federal laws.
Until November 2018, Webster served as the Laboratory’s principal associate director for Weapons programs. In this role, he integrated and delivered key capabilities of three associate directorates—Plutonium Science and Manufacturing, Weapons Physics, and Weapons Experiments—as well as several offices and programs. 
From April 2012 through June 2015, Webster served as the associate director for Weapons Physics at the Laboratory. As such, he provided leadership for two divisions and was responsible for execution and integration of the Advanced Simulation and Computing (ASC) program, the Science Campaigns, and the Inertial Confinement Fusion program.
In 2010, Webster served as deputy division leader for the Computational Physics division and as the ASC program director. In 2009, he served as LANL’s science advisor to NNSA’s deputy administrator for Defense Programs, participating in the Nuclear Posture Review.
Webster joined the Laboratory permanently in 1989 after coming to Los Alamos as a graduate student in 1984. He holds doctorate and master’s degrees in nuclear engineering from Purdue University. He earned a master’s in electrical engineering and applied physics from Case Western Reserve University, as well as a bachelor’s degree in electrical engineering.

Terry L. Grimm

BSNE 1987
Founder, President, and Senior Scientist,
Niowave, Inc.

Dr. Terry L. Grimm received his Bachelor of Science degree with highest honors in Nuclear Engineering from Purdue University in 1987. He then attended the Massachusetts Institute of Technology, where he received his PhD in Nuclear Engineering and Plasma Physics. While working on his doctorate, he was a research assistant in the Coherent Electromagnetic Wave Generation Division of the Plasma Fusion Center of the Massachusetts Institute of Technology (MIT), studying high-power, high-frequency microwave devices (gyrotrons) for electron cyclotron resonance heating of fusion plasmas.

Dr. Grimm was a senior physicist and adjunct professor at the Michigan State University (MSU) National Superconducting Cyclotron Laboratory (NSCL). In early 2000, he established the Superconducting Radio Frequency group at NSCL and supervised construction of infrastructure to develop, fabricate, and test numerous superconducting cavities. Dr. Grimm’s research on superconducting particle accelerators for the Rare Isotope Accelerator (RIA) involved the supervision and guidance of 10 staff members and six PhD students. His work on RIA laid the foundation for the $500 million Facility for Rare Isotope Beams project that was recently sited at MSU. Prior to his research with MSU, Dr. Grimm was a physicist at the Department of Energy’s Superconducting Super Collider Laboratory in Dallas, where he led a team that designed and tested the low-energy booster cavity and studied longitudinal beam dynamics.

In 2005, Dr. Grimm founded Niowave to commercialize superconducting electron linear accelerators in fields as diverse as health care and national security. It has grown to be a world industrial leader in superconducting accelerator research. In 2008, the firm qualified as the second U.S. vendor for accelerating cavities for the International Linear Collider. In 2009, Niowave became the first private company in the world to design, fabricate, and test a superconducting electron injector. Niowave has grown to 50 employees, and has received numerous awards, including being named among Michigan’s 50 Companies to Watch in 2008. In 2010, he received the IEEE Entrepreneurship Award in Applied Superconductivity.
