Since its founding in 1991, Aerosol Dynamics Inc. has worked to improve measurement methods for characterizing fine airborne particles. These particles comprise the visual haze in the atmosphere, and are important to air quality, human health and global climate.
Susanne V. Hering, founder and President, has over thirty years of
experience in the field of atmospheric aerosols. Her primary
interest is the in-situ, automated characterization of the size and
chemical composition of atmospheric particles. Dr. Hering
PhD in Physics from the University of Washington, with postdoctoral
work in Environmental Engineering at the California Institute of
Technology. After many years at UCLA, she left the academic
to form Aerosol Dynamics Inc. She has served as a Board
Member and as President of the American
Association for Aerosol Research, and in 2007 was honored as the
of the BYH Liu Award, presented by the Association in recognition of
contributions to aerosol instrumentation.
Nathan M. Kreisberg, Senior Research Scientist, holds a PhD in Physics
from the University of Texas, Austin. He has been with the
company since 1994. In recent years he has carried the
responsibility for the development of the Thermal Desorption Gas
Chromatograph system for the in-situ measurement of organic compounds
in atmospheric aerosols.
Gregory S. Lewis, Senior Research Scientist, holds a PhD in Physics
from the University of Texas, Austin, with studies in turbulent
flows. After several years in industrial research developing
advanced optical disc drives, he joined ADI in 2004, where he has
focused on the further development and application of the
company’s growth cell technology.
Steven R. Spielman, Senior Research Scientist, holds a PhD in Applied
Physics from Stanford University with studies in optical properties of
solids. He joined ADI in 2008 after several years in industrial
research in semiconductor metrology and optical data storage.
Dr. Arantzazu Eiguren-Fernandez is our Senior Research Chemist.
She is involved in the design and development of new, portable
aerosol instrumentation for time-resolved chemical speciation
of airborne particles. Her research focuses in characterizing
the physical-chemical and toxicological properties of ambient
aerosols and their adverse health effects.
