About Dr Sanki Biswas

Dr Biswas is a Postdoctoral Research Fellow in the Department of Geology, University of Johannesburg, South Africa. He is currently specializing in Applied Geology with an emphasis on organic petrology and geochemistry of coal and shale. He completed his Ph.D. in Geology from Indian Institute of Technology (Indian School of Mines), Dhanbad (India) in 2021, with a focus on the source rock characteristics, hydrocarbon generation potential, and paleo-depositional environment of Permian and Paleogene organic-rich coal/shale deposits of India. He found these areas very interesting as coal and shale are the major sources for unconventional hydrocarbon resources that will fill the future energy demand. In addition to this, they are also an alternative source for trace elements (TE), rare earth elements (REE), and critical raw materials (CRMs). He completed his master’s degree in Geology (M.Sc.) at Department of Geology, Indian Institute of Technology Kharagpur (India). The subject is very interesting and important, as it looks at some of the most essential issues in society today including energy sources and sustainability, climate change, the impacts of development on the environment, mineral resources, and natural hazards.

Research Interests:

Dr Biswas’s current research mostly focuses on the distribution and concentration of major, trace and rare earth elements in coal from the Soutpansberg Coalfield, South Africa and assessing the paleoenvironmental conditions using organic petrography and multiple organic and inorganic geochemical proxies.
