Sanjeev Dasari

Research Expertise:
Isotope-based fingerprinting of Aerosols (Organic Carbon continuum [BC, CDOM, DOC], Sulfate) and Greenhouse Gases (Carbon dioxide and Methane)

Short Bio:
Sanjeev is a researcher studying greenhouse gas release from Canadian Arctic river systems. He will employ state-of-the art laser spectroscopic and Eddy Covariance instrumentation to study the greenhouse gas fluxes and use multiple-isotope probing techniques to study their age and sources. Prior to joining our department at Oxford University, he studied Environmental Science and Engineering at the École Polytechnique Fédérale de Lausanne, EPFL in Switzerland (MSc; 2012-2014), and completed a doctoral thesis at the Department of Environmental Science at Stockholm University, Sweden (PhD; 2016-2021). His doctoral thesis looked at isotope-based constraints on sources and processing of carbonaceous aerosols and by-products in polluted environments. Upon earning his doctorate degree, Sanjeev secured the prestigious Marie-Skłodowska–Curie fellowship and conducted postdoctoral research (2021-2023) at the Institut des Géosciences de l’Environnement (IGE-CNRS) in France. At IGE, he investigated ozone layer depletion events in the ‘past’ using Antarctic and Greenland ice cores through novel proxy development using sulfur isotopes and the aspect of mass-independent fractionation (S-MIF), and also explored the role of S-MIF in ‘modern’ atmospheric aerosols. Sanjeev has secured several accolades                                                                            in different countries internationally.

Both doctoral and postdoctoral research works of Sanjeev have been covered in press and media:

2022: Antarctic ice cores reveal ozone layer depletion events in the past
2019: Role of atmospheric brown carbon in wintertime S Asia

Sanjeev has first-authored publications in notable journals such as Science Advances, PNAS, ES&T, ES&T Letters. More information can be found here.
