Dr. Rao Kotamarthi is Chief Scientist/Department Head for Argonne National Laboratory’s Atmospheric Science and Climate research group. At the University of Chicago, he is a senior fellow at the computational institute and holds complimentary positions at University of Chicago as an expert at the Energy Policy Research Institute (EPIC),He has PhD in Chemical and Biochemical Engineering from the University of Iowa and holds a certificate in strategic laboratory leadership program from the Booth School of Business, University of Chicago. 

Dr. Kotamarthi has nearly 30 years of experience in regional- and global-scale modeling of Air Quality and Atmospheric Composition, Data Assimilation, Radiative Transfer and Climate. His work leverages HPC and applied mathematics to develop models for environmental problems. He has authored over ninety journal articles and technical reports. At present, he serves as the Principal Investigator for projects funded by DOE-BER, DOE-EERE and sponsored research from Private entities on topics ranging from regional scale climate modeling to wind energy and Co-Investigator on projects funded by NSF. Most recently, he served as the principal investigator for a multi-laboratory, multi-national aerosol and cloud process measurement field study in the Ganges Valley Region of India. He has contributed to the IPCC assessment report 2 and serves on peer review panels for DOE, NSF and NASA.
