Dr. Marc L. Fischer is staff scientist in the Sustainable Energy Systems Group and Energy Technology Area at the Lawrence Berkeley National Laboratory (LBNL), and an associate researcher at the Air Quality Research Center at the University of California, Davis. Dr. Fischer's work focuses on quantifying and mitigating Earth radiative forcing due to greenhouse (GHG) gases and human habitation, and development of sustainable solutions for energy related environmental problems. The work includes development and application of measurement technologies for atmospheric trace gases, modeling of atmospheric GHG concentrations and solar radiative forcing in response to air pollution, quantification of GHG emissions from facility to regional scales, and identification of cost-effective options to mitigate emissions and reduce radiative forcing. Fischer received B.S., M.S. and Ph.D. degrees in Physics from the Massachusetts Institute of Technology, University of Illinois, and University of California, Berkeley, respectively.
