Natchapon Jongwiriyanurak | Chiang Mai University

About Me

My name is Natchapon Jongwiriyanurak, though I also go by “Pong”. I completed my PhD in Geographic Information Science at SpaceTimeLab, Department of Civil, Environmental and Geomatic Engineering, UCL, supervised by Dr James Haworth and Dr Nicola Christie.

My research explores how advanced methods can be applied to real-world challenges in the built environment, with a particular focus on GIScience, multimodal data, and models for applications in transportation and urban analytics. During my PhD, I was also a visiting researcher at the Applied Geotechnologies Research Group, CINTECX, UVigo in Spain.

I will join the Department of Civil Engineering at Chiang Mai University as a Lecturer in the second semester of 2026.

My current research interests include crowdsourced and citizen-generated data as urban sensors, naturalistic studies of walking, hiking, cycling, and motorcycling, and the use of computer vision and multimodal models for understanding cities and transportation systems.
