Vita
Dr. Mulholland received his Ph.D. from Cornell University in 1973. He has worked at the National Institute of Standards and Technology as a NRC Postdoctoral Fellow, research chemist, Smoke Dynamics Group Leader, and member of the NIST Program Office. He has been active in the characterization of smoke particulate and other aerosols and his research has impacted the fields of fire safety, fire suppression, climate change, and oil spill mitigation. He has also been active in the development of particle calibration standards used by the Semiconductor Industry for calibrating microcontamination instrumentation. He has developed several new aerosol measurement techniques and has a joint patent on a method for producing pure metal aerosols.
