Andy Haefner is currently a research scientist in the Applied Nuclear Physics group at Lawrence Berkeley National Laboratory. He leads several projects focused on real-time 3D gamma-ray imaging and mapping from handheld and unmanned systems for applications ranging from defense and international nuclear safeguards to environmental contamination mapping in Fukushima Prefecture, Japan. Andy and his team have fielded this 3D gamma-ray mapping technology in support of several measurement campaigns in Fukushima Prefecture, Japan, as well as field demonstrations across the United States. Andy has been conducting research on algorithms for processing radiation data, focused on gamma-ray image reconstruction algorithms and contextual sensor data fusion for the past 7 years. He began this research as a graduate student and has continued to develop this work as a principal investigator. Andy received a Ph.D. in Nuclear Engineering from University of California, Berkeley in 2014. He holds two Bachelor’s degrees from the University of Michigan in Radiological Sciences and Music.
