Profile Summary

Ronaldo Pornillosa Parreño Jr., a Member of The Royal Society of Chemistry (MRSC), UK. Has a PhD in Chemical Engineering received from the Department of Chemical Engineering, De La Salle University in Manila with MSc in Energy Engineering at the University of the Philippines Diliman and BSc in Chemical Engineering at University of Santo Tomas, Manila. He completed his research exchange program at the Chemical Engineering Department of National Tsing Hua University in Taiwan to develop nanofiber-based membrane using novel combination of polymeric materials that have useful properties for high-performance applications. Ronaldo's researches are in the multi-disciplinary field of Material Development, Sustainable Energy and Chemical Engineering. His current project is 'Design of Electrospun Nanofibers with Derived Functional Properties' for membrane of fuel cell. His research involves inverse vulcanization, electrospinning, membrane fabrication, thermal crosslinking, polymer blending, miscibility of polymer blend, functionalization and surface modification, sulfonation reaction kinetics and mechanisms, surface-initiated grafting, ozone treatment modification and composite with nanofibers and fillers. A Professional Chemical Engineer by Engineers Australia since 2016, skilled in the application of chemical engineering principles in process design and optimization, thermodynamics, fuel and energy conversion, technology verification of waste-to-energy technologies, test and analysis methods as well as other relevant tools and techniques in chemical engineering such as experimental design and statistical analyses, simulation & modeling, resource efficiency and cleaner production, operations research techniques & problem solving methods, cost estimation and profitability evaluation, green energy and technologies, laboratory management and maintenance. Lab skills include material characterization using FTIR, DSC, TGA, XPS, SEM-EDX, and WCA. Other skills include project management, environmental management, energy management, renewable energy technologies, energy efficiency & conservation, energy audit, green building practices, waste management, QMS (ISO 9001) & internal audit and calibration.
