Hamza El-Asaad was a Postdoctoral Research Associate at Science and Global Security until November 2024. Previously he was a Stanton Nuclear Security Fellow at Texas A&M University, working on environmental dynamics of radioactive materials, and a science and engineering researcher in the Chemistry, Environment and Radiation Division of the Nuclear Science and Engineering Center at the Japan Atomic Energy Agency with a focus on the dispersion of radioactive materials following nuclear disasters and on Fukushima decontamination efforts. He also worked on both Comprehensive Nuclear Test Ban Treaty and International Atomic Energy Agency projects in the Integrated Support Center for the Nuclear Non-proliferation and Nuclear Security Division of the Japan Atomic Energy Agency. He holds a PhD in Nuclear Engineering and a Master's in Environmental Engineering from the Tokyo Institute of Technology, and a Bachelor of Science specializing in physics and computer science from the University of Calgary, Canada.
Research Interests
My research engages two overlapping areas: understanding radiological contamination and clean-up from nuclear facility disasters and nuclear weapon explosions and strengthening the role of public and environmental safety and security as factors in policy making on reducing risks from nuclear energy and nuclear weapons. My current work uses computer simulations to model radiological dispersion from nuclear disasters and past nuclear weapon tests to assess risks and consequences and to formulate science-based strategies and regulations for nuclear safety and security, preparedness, and response and recovery measures focused on victim assistance and environmental monitoring and remediation.
