YuYe J. Tong, Ph.D.
Dr. YuYe Tong is a Professor in the Department of Chemistry and the Program Director of Environmental Metrology & Policy. He is an expert in Analytical Chemistry, Physical Electrochemistry, in situ Spectroelectrochemistry, the synthesis of metal-based nanomaterials, and fuel-cell related electrocatalysis and clean energy science
Steven Metallo, Ph.D.
Dr. Steve Metallo is an Associate Professor of biochemistry in the Department of Chemistry. The research in his group is decidedly interdisciplinary, involving aspects of chemical biology, biophysical chemistry, and surface chemistry. The three specific areas in which we work are: small molecule binders of intrinsically disordered proteins, macromolecular crowding effects focused on nucleic acids and protein-nucleic acid interactions, and engineering of protein-surface interactions.
Sarah Stoll, Ph.D
Dr. Sarah Stoll is a Professor of Chemistry in the Department of Chemistry. Research in the her lab has focused on the synthesis and study of magnetic nanoparticles. Magnetic nanoparticles are of interest for electronics applications (data storage), biological systems (particularly for separations and MRI), as well as fundamental questions about magnetism on the nanometer length scale. Many of our projects involve the synthesis of novel magnetic nanoparticles or the incorporation of magnetic clusters and nanoparticles in larger superstructures. We are also interested in developing systems with novel magneto-optical, luminescence, non-linear optical properties.
Department of Human Science Faculty
Rosemary Sokas is a Professor in the Department of Human Science at the Georgetown University School of Nursing and Health Studies. Her publications address the role primary care providers play in addressing the prevention needs of under-served working populations, and etiologic and intervention studies targeting hazards faced by construction workers, healthcare workers, immigrant day labor and home care workers, including the impact of contingent work and the need for supply chain and other policy interventions.

Carlos Gonzalez, Ph.D.
chief, division of chemical sciences
Dr. Gonzalez joined NIST in 1997 as a member of the Computational Chemistry Group within the Physical and Chemical Properties Division. Dr. Gonzalez was appointed to the position of Chief, Chemical and Biochemical Reference Data Division in 2008. In 2012, Dr. Gonzalez was appointed to the position of Chief, Chemical Sciences Division.
Katrice Lippa, Ph.D.
group leader, Organic chemical measurement sciences group
Dr. Katrice Lippa presently serves as the group leader of the Organic Chemical Measurement Science Group. Before that, she was Scientific Advisor for the Chemical Sciences Division to develop and promote reference material and data products together with chemical informatics tools that will span and connect divisional project areas (clinical, metabolomics, forensics, environmental and chemical manufacturing). She also represents NIST in the InterAmerican Metrology System (SIM) and the Consultative Committee for Amount of Substance-Metrology in Chemistry (CCQM) to develop metrology tools for traceability and to establish equivalence among measurements made by national metrology institutes (NMIs). Her current research directions are in quantitative NMR techniques for the characterization of pure substances as well as organic constituents in biological and natural matrices, in addition to advancing metrologically-sound methods for ensuring chemical traceability. As a research analytical chemist, Katrice has extensive experience in trace-level environmental organic measurement techniques (chromatography-mass spectrometry) and implementation of structure-reactivity/molecular modeling tools to help solve chemical measurement problems.
Regina Easley, Ph.D.
Dr. Regina Easly is a research chemist in the Inorganic Measurement Science Group under the Chemical Sciences Division. Her current research focuses on the traceability of pH measurements in seawater by combining electrochemistry, spectrophotometry, and quantitative nuclear magnetic resonance spectroscopy (qNMR). As an analytical chemist, Regina has extensive experience in physical organic chemistry and environmental chemistry. While an oceanographer, she participated in several research cruises and freshwater field deployments to examine nutrient concentrations and the inorganic carbon dioxide system using novel in situ sensors. Her career path has been highlighted by American Chemical Society’s C&CN.
Dr. Antonio Possolo is a NIST Fellow and the Chief Statistician in the Statistical Engineering Division. Besides his current role at NIST, he has had over 20 years of experience as a statistician in industry (General Electric, Boeing) and as an assistant professor of statistics (Princeton University, and University of Washington). His areas of specialty include spatial statistics and modeling of spatio-temporal phenomena, environmental remote sensing, foundations of probability theory and of statistical inference, and measurement uncertainty. He is also fluent in Portuguese, Spanish, and French.
William Guthrie, M.S.
William Guthrie is the Chief of the Statistical Engineering Division. For over 25 years, he has collaborated with NIST scientists and engineers to apply statistical methods to solve problems in semiconductor and microelectronic metrology, building materials research, and chemical metrology. His statistical interests include uncertainty assessment, Bayesian statistics, design of experiments, calibration, modern regression methods, and statistical computation.
Adam L. Pintar is a research statistician in the Statistical Engineering Division.He earned a B.S. in 2003 and M.S in 2004 in Mathematics from Pittsburg State University.
