Jiann C. Yang (Fed)

Dr. Yang joined NIST in 1990 as a NIST/ASEE Postdoctoral Fellow and is presently Deputy Chief of the Fire Research Division. The Division develops and utilizes measurement science to enhance the disaster resilience of buildings and wildland-urban interface communities, improve fire fighter safety and effectiveness, and enable performance based design through cost-effective engineered fire safety for people, products, structures, and communities.

He has conducted research on fire dynamics and suppression, halon replacements, droplets and sprays, aerosol dynamics, micro-gravity combustion, two-phase flows, hydrogen fire safety, greenhouse gas emission measurements, and transportation fire safety. He has co-authored over 100 archival and conference articles and two book chapters. He was awarded the U.S. Department of Commence Bronze Medal in 2000 and Gold Medal in 2005 and the SAE International Arch T. Colwell Merit Award in 2008. He is a Fellow of the American Society of Mechanical Engineers (ASME).
