Dr. Rao Kotamarthi is an atmospheric scientist in the Environmental Science Division at the Argonne National Laboratory. He has more than 25 years of experience in regional- and global-scale modeling of weather, atmospheric chemistry, and climate, and more than 60 publications. He is currently Argonne’s Manager for the Atmospheric Sciences and Climate Research group and serves as the Chief Scientist in the Environmental Science Division; he is also a senior fellow at the Computational Institute at the University of Chicago. His current research interests are in high-spatial resolution regional scale climate modeling; modeling atmospheric aerosols and their radiative forcing; developing methods for model inversion and data assimilation into atmospheric trace gas models; atmospheric modeling of flow in the boundary layer for wind energy applications; biogeochemical models and carbon storage changes from shifts in land use patterns; and integrated models for climate assessments. He currently serves as a principal investigator for projects funded by DOE and DOD.
