Profile Summary

I am a PhD-qualified environmental scientist and engineer from IIT Bombay, specializing in water disinfection, nanocomposite membrane technology, electrochemical treatment processes, and nanomaterial engineering. My doctoral research focused on designing and optimizing laser-induced graphene (LIG)-based electroconductive surfaces and membranes for advanced water purification, including microbial inactivation, emerging contaminant degradation, and controlled release of disinfectants for long-term water treatment applications. My research portfolio spans both fundamental and applied work: from mechanistic understanding of electrochemical disinfection and electric field-driven contaminant removal, to COMSOL-based process modelling for optimizing electrochemical treatment systems. I also have hands-on experience with photothermal and electrothermal desalination processes using graphene interfaces and solar energy harvesting. I have authored and co-authored 11+ peer-reviewed publications in high-impact journals, including ACS Applied Materials and Interfaces, Environmental Science: Nano, Environmental Science: Water Research & Technology, ACS Omega, and Water Research, and serve as a peer reviewer for journals including NPJ Water, RSC Advances, and Journal of Colloid and Interface Science. As a freelance consultant, I offer expertise in: Scientific literature reviews and state-of-the-art analyses in water treatment, membranes, and nanomaterials Experimental design and research methodology for water purification, electrochemical treatment and membrane technology Manuscript writing, editing, and peer review preparation for environmental science journals COMSOL modelling for electrochemical and environmental process optimization Technical consulting for R&D teams working on water quality, emerging contaminants, or advanced material development I also work as a science communicator, translating complex environmental research into accessible content for broader audiences.
