Peter joined the Radiation and Nuclear Detector Systems group in 2006. He has been a major contributor to the Neutron Scatter Camera project supported by NA-22 where he has led data analysis, development of image processing tools, Monte Carlo detector modeling, and performance characterization toward future design. He is currently the Principal Investigator for an NNSA funded project to develop a coded aperture neutron imager in collaboration with ORNL, an NNSA funded project to develop a digital fast neutron multiplicity detector for the characterization of fissile material, and a Laboratory Directed Research and Development project to develop a fast neutron resonance tomography system for the detection of explosives in air cargo. Peter is also the Sandia point of contact for the Nuclear Science and Security Consortium (NSSC). He was awarded a Ph.D. in Gamma-ray Astrophysics from the University of California Davis.
