Profile Summary

Process engineer and PhD researcher (thesis submitted) with 4+ years of experience in waste-to-energy systems, reactor engineering, and sustainable process optimization across biological and thermochemical conversion technologies. My work focuses on carbon conversion and sustainable engineering systems including anaerobic digestion, pyrolysis, gasification, and integrated reactor/process systems. I have hands-on experience designing, operating, troubleshooting, and optimizing laboratory and pilot-scale systems for both research and industrial applications. Core technical areas include: • Anaerobic digestion and bioprocess operation • Pyrolysis and gasification systems • Reactor and process optimization using Design of Experiments (DoE) • Mass and energy balance modelling • Techno-economic and carbon balance analysis • Scale-up analysis and process troubleshooting • Technical documentation including P&IDs, SOPs, and process descriptions • HAZOP-based process safety support • Sustainability and environmental systems analysis Alongside experimental and operational work, I use analytical and engineering tools including Python, Excel, OriginPro, and Minitab for process analysis, data interpretation, optimization, and modelling workflows. I have authored 11 peer-reviewed publications with 100+ citations in the areas of environmental engineering, sustainable energy systems, and waste valorization. My background combines academic research, process engineering, and practical system operation, allowing me to contribute to both technical research and real-world engineering challenges. Open to technical consulting, feasibility studies, literature reviews, process analysis, sustainability assessment, research support, and engineering projects related to sustainable technologies and waste-to-energy systems.
