Jaganmoy Jodder

Jaganmoy Jodder is a Research Fellow at the Centre for Planetary Habitability, University of Oslo, with affiliations to multiple international institutions including the Evolutionary Studies Institute at University of the Witwatersrand (South Africa) and the Department of Geology at University of Johannesburg (South Africa). His research focuses on early Earth processes, biogeochemical cycles, and planetary habitability through multidisciplinary studies of Archaean rock records.

• B.Sc, Presidency College, University of Calcutta (2010)

• PhD, Department of Geology, University of Johannesburg (2020)

His work integrates petrology, geochronology, geochemistry, geobiology, and radiogenic-stable isotope analysis to investigate ancient volcano-sedimentary rocks from key cratons like Singhbhum, Kaapvaal, and Pilbara. These studies aim to reconstruct early Earth surface conditions and understand the co-evolution of crustal processes with microbial life.

Recent publications highlight his contributions to understanding Archaean seawater chemistry (via Nd isotopes in iron formations), early Earth magnetism (zircon magnetization), and craton evolution (structural and geochemical frameworks). His research spans both terrestrial and planetary contexts, emphasizing habitable conditions.
