Under the supervision of Professor [[User:J.M.Pearce|Joshua M. Pearce]], Riya is actively contributing to the fascinating realm of open-source appropriate technology (OSAT) within the [https://www.appropedia.org/Category:FAST Free Appropriate Sustainable Technology (FAST)] research group. Riya also has completed her MESc. in ECE from UWO under the same research group.\n\nHer current research endeavors are centered around the meticulous examination of the life cycle analysis (LCA) of various solar PV systems and products crafted from recycled plastic. Riya is committed to leveraging the power of sustainable technologies to address pressing global issues, such as poverty reduction and environmental sustainability.\n\nRiya holds a Bachelor of Science degree in Electrical and Electronic Engineering, majoring in power systems, from United International University (UIU), Dhaka, Bangladesh. Her undergraduate thesis showcased her innovative thinking and problem-solving skills, focusing on investigating the techno-economic feasibility of a pump-back hydroelectric reservoir for an existing hydropower station using solar energy as an alternative to traditional peaking power plants. It demonstrates her commitment to advancing renewable energy solutions.\n\nRiya's diverse research interests span across renewable energy, solar PV systems, agrophotovoltaic systems, sustainable technologies, recycling, life cycle analysis, power electronics, and power systems. Her academic journey and research pursuits reflect a profound dedication to creating impactful solutions for a more sustainable and eco-friendly future. As she continues to delve into the intricacies of engineering and sustainability, Riya Roy stands poised to make significant contributions to the field, leaving an indelible mark on the intersection of technology and environmental responsibility.\n\n== Completed Projects and Publications ==\n\n==== Ongoing in 2025: ====\n\n# DIY 3D printed industrial fan\n# AC Solar photovoltaic module testing for residential applications\n# [[LCA of peat cup and plastic cup]]\n# Comparative LCA between multi c-UMG Si solar module vs conventional one\n\n===Completed in 2024===\n====Completed:====\n\n# [https://doi.org/10.1016/j.ijhydene.2025.03.104 Comparative LCA of grey hydrogen, blue hydrogen, green hydrogen, and pale-blue hydrogen]\n#[https://www.appropedia.org/Life_Cycle_Carbon_Emissions_Savings_of_Replacing_Concrete_with_Recycled_Polycarbonate_and_Sand_Composite LCA of sand-plastic brick]\n#[https://papers.ssrn.com/sol3/papers.cfm?abstract_id=5061658 Validation of a Portable Open-Source Diy I-V Curve Tracer]\n# [https://www.preprints.org/manuscript/202412.2429/v1 Life Cycle Carbon Emissions Savings of Replacing Concrete with Recycled Polycarbonate and Sand Composite]\n# [https://ir.lib.uwo.ca/etd/10648/ MESc.
