Li Piin Sung

Physicist, Materials and Structural Systems Division

National Institute of Standards and Technology (NIST)

Lipiin Sung received her Ph.D. in Physics from UC Santa Barbara in 1993 and joined National Institute of Standards and Technology (NIST) soon after. She worked as a postdoc and contractor in different Laboratories at NIST on various research projects using scattering metrology. She was converted as a full-time Research Physicist in the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST) in November 2001. Lipiin's main interests are in understanding the interactions between fillers and polymeric matrix, and in investigating the impact of filler dispersion on optical, mechanical, and short-term and long-term performance properties. Since 2008, she has been the Director and project leader of NIST/Industry Polymer Surface and Interfaces (PSI) consortium. In this capability, she has taken the leadership and initiative in developing test methods for characterizing scratch resistance using scattering measurement science to articulated industry needs. Lipiin's current research efforts are on developing metrologies for surface damage and durability study of nanocomposites, and for assessment of nanoparticles release under environmental stresses (UV radiation, thermal, moisture, mechanical stresses).
