My interests are in neutron and x-ray scattering studies of soft condensed matter systems, especially mechanisms of self-assembling and the static and dynamics properties of bio-material, membrane, and polymer complex systems. I am stationed at National Institute of Standards and Technology (NIST) at Gaithersburg, MD, as one of instrumetal scientists of Neutron Spin Echo spectrometer. The technique is suitable to measure materials dynamics in nm and ns scales.
