David Shearer is Chief Scientist and specializes
in next generation transportation, energy and information technologies.
He is also an expert in policy instruments that catalyze market development
for emerging technologies, exposure assessment of indoor/outdoor air pollutants,
and climate change. Dr. Shearer has worked with a broad range of private
and public sector clients to manage environmental risk, quantify the life
cycle impacts of human activities, develop revenue generation models for
short- and long-term environmental strategies, and engage stakeholder groups
in constructive dialogue.
In past years, Dr. Shearer has focused attention on several environmental
problems. He developed a surrogate metric for estimating human exposure
to fine particulates that both assisted in assessing acute health effects
and supported the promulgation of the PM2.5 standard. In another area,
he collaborated with a team of scientists that quantified the economic
costs of air pollution in large metropolitan areas. In addition, he investigated
the psychological effects of air pollution in Los Angeles Basin with the
goal of refining public perceptions of acute and chronic air pollution
events.
Prior to CEA, Dr. Shearer was Principal Environmental Scientist for
AeroVironment Inc. He currently serves on the technical advisory boards
of the Lindbergh Foundation and the Bay School of San Francisco. He holds
a Ph.D. in environmental epidemiology from the University of California,
Irvine, a M.S. in environmental microbiology from the University of California,
Irvine, and a B.S. in biology from the University of Oregon.
