Biography

Dr. Asiri Umenga Weerasuriya has obtained BSc. (Hons) and MSc in Civil Engineering at the University of Moratuwa, Sri Lanka in 2008 and 2011 prior joing the Hong Kong University of Science and Technology (HKUST), Hong Kong in 2011. He has earned a PhD in Civil Engineering from HKUST in 2011. Dr. Asiri's research interests are broadly in Civil and Wind Engineering with special research areas of wind loading of buildings, pedestrian level wind environment, natural ventilation of buildings, air pollution dispersion in built-up areas, building design optimization, and expalinable machine learning in wind engineering applications. Dr. Asiri is an expert user in computational fluid dynamics (CFD) simualtions, experienced wind tunnel modeler, and  avid explorer in machine learning applications in wind engineering.
