PhD (IIT Delhi) Environmental Engineer | Sustainability, CCUS & Grant Proposal Specialist

Profile Summary

I am a Ph.D. in Environmental Technology & Sustainability from IIT Delhi, with over a decade of academic and applied experience in environmental systems engineering, carbon management and waste-to-resource technologies. I hold an M.Sc. (Tech.) in Environmental Science & Technology from BHU and qualified as a NET-JRF ranked candidate. I also completed a Project Management diploma from the University of Hyderabad, strengthening my ability to translate scientific concepts into structured, execution-ready projects. My expertise spans: • Carbon Capture, Utilisation & Storage (CCUS) systems • Wastewater treatment and biomass valorisation • Life Cycle Assessment (LCA) and techno-economic evaluation • Environmental and CSR grant proposal development • Sustainability project methodology and implementation planning I have experience across research institutions, industry collaborations and NGO-driven environmental initiatives. My approach emphasises feasibility, scalability and realistic execution rather than exaggerated technical claims. I support organisations, startups, NGOs and funding applicants in developing technically rigorous, data-backed and fundable environmental project documents, sustainability strategies and research frameworks.
