Professor Andreas Enqvist is an Associate Professor of Nuclear Engineering at the University of Florida in the Department of Materials Science & Engineering. Before coming to Florida he worked as a researcher (post-doc, research assistant, visiting scholar) at University of Michigan and Oak ridge National Laboratory (ORNL). His Ph.D. was received at Chalmers University of Technology, Sweden in the Nuclear Engineering Division of the Applied Physics department in 2010. Before that he received his M.Sc. in Physics at Gothenburg University in 2005.

Working with students in our nuclear detection lab with accompanying research in neutron detection, fission physics and detector system development. Research areas include: Nuclear Security/Safeguards, neutron Recoil recoil detectors, Detector material characterization, Detector system design, and radiation transport.

Sample projects:

Radiological Source Detection and Tracking Based on Multi-Sensor Data Fusion,

This is a multidisciplinary approach to allow the tracking of the movement of radioactive sources by fusing data from multiple radiological and visual sensors. The goal is to improve the ability to detect, locate, track and identify nuclear/radiological threats.

Our key idea is that such widely available visual and depth sensors can impact radiological detection, since the intensity fall-off in the count rate can be correlated to movement in three dimensions. To enable this, we pose an important question; what is the right combination of sensing modalities and vision algorithms that can best compliment a radiological sensor, for the purpose of detection and tracking of radioactive material? Similarly what is the best radiation detection methods and unfolding algorithms suited for data fusion with tracking data?
