Bio

After obtaining his BS in Physics at NC State in 1990, Professor Huffman earned his MA (in 1992) and his PhD (in 1995) in Physics at Duke University. Paul then spent three years as a postdoctoral fellow at Harvard University before taking a staff position at the National Institute of Standards and Technology in Gaithersburg, MD. Paul joined the Physics department in 2004 as an Associate Professor with a 5-year joint appointment with the Physics Division of the Oak Ridge National Laboratory. Paul is also a member of the Triangle Universities Nuclear Laboratory.

Research Description

Paul's research efforts are centered around using neutrons to both test the Standard Model and investigate the weak interaction through beta decay and neutron-nucleon processes. This includes performing experiments in these areas and in the development of new neutron sources for use in future fundamental neutron physics experiments. Paul has also been involved in the development of a neutron imaging facility for fuel cells.
