About

I am a pioneering researcher in the field of environmental biotechnology, with a particular focus on the bio-mitigation of industrial pollutants using innovative bioreactor systems. I have completed my Doctor of Philosophy under the esteemed guidance of Prof. Smita Raghuvanshi at the Birla Institute of Technology and Science, Pilani.
My research centers on the utilization of chemolithotrophic bacteria for the bio-mitigation of flue gases such as CO2, SOx, and NOx. My groundbreaking work involves the design and implementation of bubble column bioreactors, which are capable of achieving high biomass yield and significant pollutant removal efficiencies.
My work also explores the integrated use of suspended and packed bed bioreactors for simultaneous flue gas mitigation and wastewater treatment. Through 16s metagenomics, I identified diverse microbial communities that play a crucial role in these processes. My studies have shown impressive removal efficiencies for CO2, SO2, and NO, alongside substantial biomass production. My research contributes to the development of sustainable biorefineries by converting bacterial biomass into value-added products such as biodiesel, bioethanol, and biopolymers. Utilizing advanced techniques like FT-IR, GC-MS, and NMR metabolomics, I have identified key metabolites involved in flue gas bio-mitigation pathways, highlighting the potential for producing environmentally friendly biofuels and chemicals with minimal global warming potential.
My innovative approach not only addresses critical environmental challenges but also supports various Sustainable Development Goals (SDGs) by promoting a circular economy. Through comprehensive Life Cycle Assessment (LCA) and Techno-Economic Assessment (TEA), I evaluated the environmental and economic viability of the bioreactor systems, ensuring practical applicability and scalability.
This research work stands at the forefront of environmental bioremediation, offering promising solutions for industrial pollution control and sustainable biofuel production.
