Biography
Raghu Sivaramakrishnan is a Chemist in the Gas Phase Chemical Dynamics group at Argonne National Laboratory. He received a B. Tech. in Chemical Engineering (1999) from the University of Madras, and an MS (2002) and PhD (2005) in Chemical Engineering from the University of Illinois at Chicago (Advisor - Kenneth Brezinsky), working on high pressure shock tube studies and chemical kinetics modeling on the combustion of hydrocarbon fuel components. He continued as a post-doc and research staff member (2005-2007) in Ken Brezinsky’s group before moving to Argonne as a post-doc (2007) to work with Joe V. Michael to characterize the kinetics of elementary reactions. In 2010, he was hired as a research staff at Argonne where his research interests involve applications of theoretical and experimental chemical kinetics to model chemical conversions of gas-phase molecules relevant to combustion and atmospheric chemistry. He is a past awardee (2006) of the Bernard Lewis Fellowship from the Combustion Institute. He has been a chemical kinetics colloquium co-chair for the 37th (2018) and 38th (2020) International Combustion Symposia and is an Associate Editor (2020 onwards) for the Proceedings of the Combustion Institute.
