Biogeochemistry Group focuses on the study of physico-chemical, geological and biological processes and reactions that governs the characteristics of natural environment. The Group also studies the biogeochemical cycles of elements and their dynamics/fate with respect to the changing climate and environment together with signatures of paleoclimate proxies. We employ geochemical and microbiological modeling along with species/isotopic level studies to interpret the environmental processes and their effects on the global biogeochemical cycles. The thrust areas of research include biogeochemical studies of water environs including estuarine, coastal, springs and fresh waters in main land/island systems with emphasis on solute fluxes/dynamics and speciation, pesticide/organics fragmentation and degradation, water quality monitoring, pollution assessment and mitigation strategies.
