Andreas Enqvist

Andreas Enqvist is a Professor in the Department of Materials Science and Engineering at the University of Florida, College of Engineering, where he leads the Enqvist Research Group (LOKE). The group is part of the Nuclear Engineering Program and actively contributes to national and international efforts in nuclear nonproliferation, safeguards, and radiation detection. They are members of the US Department of Energy's National Nuclear Security Administration (NNSA) Consortium for Monitoring, Technology, and Verification (NA-22) and collaborate with NASA on planetary protection research.

Their research focuses on the detection and modeling of neutron and gamma-ray signatures from nuclear materials, particularly fresh and spent nuclear fuel. Key areas include nondestructive assay, neutron spectroscopy, detector development (especially He-4 scintillators), data fusion with vision systems, and simulation using tools like MCNPX-PoliMi and SCALE. The group conducts experiments at the University of Florida Training Reactor (UFTR) and the National Criticality Experiments Research Center (NCERC).

The recent publications (2020–2025) reflect a strong emphasis on optimizing detector configurations, neutron scatter cameras, pulse shape discrimination using machine learning, dry cask monitoring, and advanced data fusion techniques. There is a clear trend toward integrating physics-based models with AI/ML methods and developing compact, field-deployable systems for nuclear security applications.

• Member, NNSA NA-22 Consortium for Monitoring, Technology, and Verification
• Collaborator, NASA Planetary Protection Research Program
• Principal Investigator, NEUP-funded projects

The group mentors several students and researchers, including Cat, Brice, Sai, Jaylen, Nuo, and Joseph. They have secured funding from NNSA and DOE for projects related to nuclear safeguards, verification technologies, and training reactor applications. Their work bridges fundamental nuclear physics with practical engineering solutions for global security and space exploration.

The Enqvist Research Group operates within the University of Florida’s Nuclear Engineering infrastructure, utilizing the UF Training Reactor and advanced simulation capabilities. They collaborate with national laboratories and other university teams within the NNSA consortium, forming a key part of a larger network dedicated to advancing nuclear monitoring technologies.
