Dieter Schneider is a co-principal investigator in the Macromolecular Crystallography Research Resource (PXRR) which provides facilities and support at the National Synchrotron Light Source for the benefit of outside and in-house investigators.   The PXRR is supported by the NIH's National Center for Research Resources and the DOE Office of Biological and Environmental Research in its mission to create optimal facilities and environments for macromolecular structure determination by synchrotron X-ray diffraction.   With a staff of about 25, the PXRR innovates new access modes such as FedEx crystallography, builds new facilities, currently on the X29 undulator, advances automation, develops remote participation software, collaborates with outside groups, teaches novice users, and supports visting investigators with 7day, 20 hours staff coverage.

Research Interests

Applications of neutron small-angle scattering for the structure determination of macromolecular complexes are the focus of this program. Development of scattering techniques, computational methods, and neutron instrumentation is pursued to maintain a vigorous outside user program on the H9B SANS Beamline at the High Flux Beam Reactor.

While the HFBR is shutdown, development of a neutron fiber diffraction camera is continued. A dual purpose instrument for the measurement of diffuse scattering and fibre diffraction was built jointly with the BNL Physics Department and is being tested at the National Institute of Standards and Technology. Neutron image plate detectors are used to record diffraction at a high resolution. The new capabilities will be applied by structural biologists who are deriving the organization of multicomponent macromolecular fibrous complexes, probing the conformational changes in contractile proteins, and determining intermolecular forces.

Additionaly, I am the beamline scientist at the NSLS beam line X26C, which is operated by a four-membered PRT including the BNL Biology Department, Cold Spring Harbor Laboratory, the State University of New York at Stony Brook, and the Georgia Research Alliance.
