Introduction
I am currently a DST Inspire Faculty at IISc, working with Dr. Sambuddha Misra. I have done my PhD from IIT-K under Dr. Indra Sen. My PhD work focused on the anthropogenic imprint on the biogeochemical cycle of Platinum Group Elements and Lead. However for my post doc, I have switched focus on the natural biogeochemical cycling of a major element, primarly Mg. I am looking into the Mg cycling in a plant-soil profile scale. Leave a text if you are interesred to know more.

Platinum group element (PGE) is among the emerging airborne contaminants mainly emitting from automobile catalysts. The ambient PGE concentration in Asia is expected to rise due to an increase in vehicle sales over the last two decades. Of all the Asian countries, the automobile industry in India has grown at a spectacular rate (> 50% in the last 1...
Automobile catalytic converters derived Platinum Group Elements (PGE) and gasoline combustion, smelters, mining, and coal combustion derived lead (Pb) are important and emerging environmental contaminants. Tracing the pathways of these pollutants is therefore critically important to identify the source and sink area of PGE and Pb in the Earth’s sur...
Measurement of Platinum Group Element (PGE: Ru, Rh, Pd, Os, Ir, and Pt) and Rhenium (Re) in environmental samples is a difficult task due to their ultra-trace level concentrations, and these metals suffer from severe isobaric and polyatomic interference. These kinds of issues have been solved for environmental samples having simple matrices such as...
Particulate impurities in form of windblown mineral dust and soot darkens the ice surface and as a result directly increases the heat absorption, and by response causes ice melting. These impurities are accreted on the ice surface by wet precipitation or aeolian deposition. Currently, our understanding of the processes that controls the atmospheric...
Anthrobiogeochemical cycles have been a subject of scientific research for many decades as they are important for identifying possible sources, sinks, and pathways of an element in the environment. In this study, we quantified global cycles for the platinum group elements (PGE; platinum (Pt), palladium (Pd) and rhodium (Rh)). We quantified the stoc...
Platinum Group Element (PGE) pollution on the Indian subcontinent is a growing concern because vehicle sales in India have rapidly increased over the last decade, and it is well known that automobile catalytic converters are one of the major source of anthropogenic PGE in the environment. Despite the rapid growth of the Indian automobile industry,...

I have collected aerosols for one year from Himalayan region. There is a sudden change in the lead isotope signature during winter times. I am trying to find some atmospheric process that may be affecting this sudden decrease in Lead content in atmospheric dust.
I want to characterize the direct and indirect atmospheric deposition of dust into the river water and distinguish it from other components which are also contributing to the river water chemistry.
