Summary
Assela Pathirana is an Associate Professor and water infrastructure asset management specialist with 13+ years of applied research and teaching experience across UNESCO-IHE and UNDP roles, grounded in a PhD from the University of Tokyo. He combines deep domain knowledge in hydrology and atmospheric modelling with hands-on software engineering—proficient in Python, C/C++, Java and high-performance computing—to build socio-technical tools and integrate water simulators (EPANet, SWMM) with AI workflows. Author of 65+ peer-reviewed papers cited widely, he has led 30+ research and capacity-building projects across low-, middle-income and European contexts, often as principal investigator or chief technical advisor. His work uniquely blends stakeholder co-design (learning and action alliances, Agile urban adaptation) with crowdsourced sensing, LoRaWAN monitoring and big-data pipelines (Apache Spark) to make advanced water solutions accessible. He trains practitioners annually through an intensive modelling bootcamp and publishes popular Python libraries that bridge legacy simulators and modern AI toolchains. Practical, interdisciplinary, and UN-experienced, he brings both institutional understanding and code-level fluency to water innovation.
