Research Interests

Dr. Bowden’s research interests include neutrino physics, reactor antineutrino detection technology, nuclear data measurement, fast neutron imaging, and fast neutron spectroscopy. During his career at Sandia and Lawrence Livermore National Laboratories, he has successfully combined the pursuit of fundamental physics measurements with the effort that seeks to apply cutting edge technologies to real-world problems. He is the co-spokesperson of the PROSPECT neutrino oscillation experiment and a member of the NIFFTE collaboration.
