Kelvin received his B. Eng. (Geomatics)(Hons) from UniversitiTeknologi Malaysia (UTM), Master of Remote Sensing & GIS from Universiti Putra Malaysia (UPM) and completed his Ph.D specialize in Hydrography from UTM. He is currently a Professional Technologist (P. Tech) registered under the Malaysia Board of Technologist (MBOT), Fellow of Royal Institution of Surveyors Malaysia (RISM), Professional Member of Institution of Geospatial and Remote Sensing Malaysia (IGRSM) and Member of Institute of Electrical and Electronics Engineers (IEEE).His expertise lies in hydrography, marine surveying, and applied geospatial engineering, with research interests encompassing bathymetric mapping, satellite-derived bathymetry, coastal and offshore surveying, and marine spatial analysis. He has published more than 16 indexed journal articles and has led or contributed to several competitive research grants and community-based projects, particularly in support of coastal management and climate change mitigation initiatives. His work integrates advanced geospatial technologies with rigorous field-based hydrographic surveys, aiming to enhance coastal resilience, maritime safety and sustainable marine and urban development.
