| (L to R) Josh Long, Chen-Yu Liu, and Roger Pynn IUCF's newest faculty members. |
Roger Pynn obtained his doctorate degree from Cambridge University in England in 1969 for experimental and theoretical work on the phonon spectra of hexagonal simple metals. Since that time, he has scattered neutrons in Sweden, Norway, Denmark, Russia, Japan, France, Germany and the United States. He has worked in a variety of fields including structural phase transitions, low dimensional magnets, soft condensed matter and biology. He came to the US (for the second time) in 1987 as Director of what has since become the Manual Lujan Jr. Neutron Scattering Center at Los Alamos National Laboratory. After a 13-year management career at Los Alamos, which included periods as the Laboratory's Program Manager for Basic Energy Sciences and as Division Director of the Los Alamos Neutron Science Division, he returned to research in 2001. Since that time, he has developed programs in the design of novel neutron instrumentation and in the biophysical research using neutron scattering. He will continue working in these areas at IUCF and is eager to explore the potential of a university based neutron source which he believes can make unique contributions to scientific research, education and the development of new neutron scattering techniques.
Chen-Yu Liu recently joined the nuclear physics group at IUCF. She will be developing an intense Ultracold Neutron source based on anti- ferromagnetic solid oxygen. The research on the Ultracold Neutron source will be conducted using the LENS source at IUCF. She is also working on another low temperature experiment, using garnets to search for the electric dipole moment (EDM) of the electron. High precision measurements of this kind allow us to search for the evidence of Time Reversal Symmetry Breaking. Chen-Yu was originally from Taiwan. She received her Ph.D. from Princeton University at 2002, and then worked at Los Alamos National Laboratory for three years as the Director's funded Postdoctoral Fellow.
Josh Long's areas of research include experimental tests of fundamental physics with neutrons and tests of gravity at length scales below one millimeter. He received his Ph.D. in physics from Johns Hopkins University in 1997 on a search for neutrino oscillations with the NOMAD experiment at CERN. This was followed by five years of postdoctoral work at the University of Colorado where he developed an experiment to search for new gravitational-strength forces in the 100-micron range. For the past three years, Dr. Long has been a staff scientist at Los Alamos concentrating on a new measurement of the neutron electric dipole moment (EDM). At IUCF, Dr. Long plans to continue his work with both the EDM and short-range gravity experiments while getting involved in additional fundamental neutron measurements.
