Sourav Das

Postdoctoral Fellow
+1 (437) 518-9730



Sourav joined as a post-doctoral fellow in University of Toronto after completing his Ph.D. from Texas A&M University, USA and bachelor’s from Indian Institute of Technology, Kharagpur, India. His doctoral work focused on laboratory scale method development for analyzing isotope in low mass urban aerosols. In addition, he developed statistical and computational models to trace sources of urban aerosols using isotopic and ultra-trace elemental composition. He is currently working with Dr. Clare Wiseman to assess the sources, elemental composition, and toxic potential of urban road dust. Sourav aims to bring in multi-disciplinary concepts to better understand the behavior of aerosols from source to sink.
