The Benjamin Y. H. Liu Award
American Association for Aerosol Research
Benjamin Y. H. Liu was born in Shanghai, China in
1934. He grew up in war-time China on the mainland,
went to college in Taiwan, received his B.S.M.E.
degree from the University of Nebraska in 1956, and
his Ph.D. from the University of Minnesota in 1960.
Dr. Liu began his academic career at the University of
Minnesota as an Assistant Professor. He was elected
to the National Academy of Engineering in 1987. He is
a co-founder of the AAAR and of the society's journal,
Aerosol Science and Technology, and helped establish
the International Aerosol Research Assembly. He
received the Fuchs Memorial Award in 1994 and
retired as Regents' Professor from the University of
Minnesota in 2002, where he also served as the
director of the Particle Technology Laboratory from
1973 to 1997.
Following his retirement from the University of
Minnesota, Dr. Liu became the CEO and President of
MSP Corporation, a company he co-founded with Prof.
V. A. Marple.
Prof. Liu’s contributions to aerosol science
include
• theory on aerosol sampling and transport;
• aerosol charging and precipitation;
• inertial impaction;
• filtration;
• atmospheric aerosol research; and
• contaminant particle deposition on wafers.
He and his students have pioneered the
development of many instruments and
experimental techniques including
• the vibrating orifice generator and
• the electrostatic classifier
that have provided accurate size standards
needed by the aerosol community to perform
modern aerosol experiments with high accuracy
and precision.
This award honors Benjamin Y. H. Liu for
his leadership in the aerosol community and
his own seminal contributions to aerosol
science through instrumentation and
experimental research.
The Benjamin Y. H. Liu Award
“recognizes outstanding contributions to aerosol
instrumentation and experimental techniques
that have significantly advanced the science and
technology of aerosols”.
2004 Recipients of the
Benjamin Y. H. Liu Award
Douglas R. Worsnop,
Vice President, and
John T. Jayne,
Principal Scientist,
Aerodyne Research, Inc.
Their mass spectrometer system (AMS) with molecular beam, aerosol
focusing, and thermal vaporization have created a paradigm shift in online,
size-resolved atmospheric aerosol composition.
The supporting letters all highlighted their dedication to supporting the
many AMS users to do the best science possible with the instrument.
