Georgia Harris joined the NIST Office of Weights and Measures in 1990. Her work includes proficiency testing, documentary standards activities, and education and training of laboratory metrologists, as well as metrology outreach efforts primarily at the university level. In her spare time, you can probably find her hiking, camera in hand, with her husband.

Mark McLinden received his B.S. degree from the University of Missouri-Columbia and M.S. and Ph.D. degrees from the University of Wisconsin-Madison, all in chemical engineering. He joined NIST in 1984 and is the author or coauthor of more than 100 peer-reviewed publications, and has won several awards for his refrigerants research. When not in the lab, Mark enjoys hiking the mountains of Colorado, often carrying 10 kg of large-format, i.e., film-based, old-school, camera gear; he maintains that film is not dead yet and has the landscape photos to prove it.

Konrad Lehnert is a 1993 graduate of Harvey Mudd College. He received a Ph.D. from the University of California at Santa Barbara in 1999 and did post-doctoral research at Yale. In 2003 he joined JILA and NIST. He is known for his development of quantum-limited microwave amplifiers and for investigating the quantum physics of micro-mechanical structures. While at Harvey Mudd, Konrad ran track and cross country, and he still holds the school’s record for the slowest time in an official 5K race.

He has a master's degree in engineering and an MBA.

Keana Scott is a physical scientist at NIST. She has a B.S. in engineering and applied sciences from Caltech and a Ph.D. in mechanical engineering from the University of Pittsburgh. After several years working in industry, Keana joined NIST in April 2006 to work on multi-modal bioimaging technique development and the microanalysis of biological materials using electron and ion beams. While working in the private sector, she insisted that an informatics tool she helped develop be named SEURAT after artist and inventor of pointillism Georges Seurat because of the similarity between how the tool gathers data and the pointillist painting technique.

Trivia lover and spare-time etymologist Michael E. Newman has been at NIST for 25 years and currently serves as a senior communications officer. A native of Houston, he originally planned a career as a research scientist but detoured into science communications after his first (and only) year of graduate school. His public affairs, journalistic and AV experiences prior to NIST include time as a reporter for the Houston Chronicle, a medical TV writer/producer for the University of Texas Health Science Center at Houston, a features reporter at an NPR affiliate, an ABC-TV news producer, an audiovisual production manager and media spokesman for a Fortune 500 oil and gas company, and a public affairs specialist for the National Cancer Institute.

Ann Chiaramonti Debay is a materials research engineer in the Applied Chemicals and Materials Division at NIST in Boulder, Colorado. She specializes in characterizing the atomic structure and chemical makeup of materials at the nanoscale using electron microscopy and atom probe tomography. Ann is always on the lookout for interesting new (or very old!) things to put in her microscopes.

Paul Blanchard started his NIST career as an undergraduate research assistant in 2005. After graduating with a B.S. in engineering physics from the Colorado School of Mines, Paul began working for NIST’s Applied Physics Division full time. When he’s not taking things apart atom-by-atom, he might be found in his home music studio writing songs that are never quite finished.

Since becoming Metric Coordinator in 2005, Elizabeth has worked to support voluntary conversion to the International System of Units (SI), commonly known as the metric system, in the U.S. In addition to providing information and assistance to federal, state and local weights and measures officials, business, industry, educational institutions, and the public concerning the SI, she also identifies opportunities for increasing its understanding and use in trade and commerce. When she’s not extolling the virtues of converting to metric, she enjoys camping and hiking with her husband and two teenage sons.
