Wai Cheong Tam (Fed)

Mechanical Engineer

Dr. Wai Cheong Tam (Andy) is a mechanical engineer in the Fire Fighting Technology Group of the Fire Research Division of the Engineering Laboratory at the National Institute of Standards and Technology (NIST). Prior to his tenure, Andy was a NRC Postdoctoral Research Associate at NIST after receiving his Ph.D. in Mechanical Engineering from the Hong Kong Polytechnic University, where he developed the neural network based radiation solver (RADNNET-ZM) for heat transfer analysis in fire research with his thesis advisor, Professor Walter W. Yuen. Currently, his research interests are thermal radiation heat transfer, machine learning for interdisciplinary research studies on smart fire fighting, fire fighters’ health monitoring, and cooktop fire prevention, and heat transfer analysis for lithium-ion batteries.

How AI Could Alert Firefighters of Imminent Danger

JUNE 1, 2021
Firefighting is a race against time. Exactly how much time? For firefighters, that part is often unclear. Building fires can turn from bad to deadly Building fires can turn from bad to deadly in an instant, and the warning signs are frequently difficult to discern amid the mayhem of an inferno.
