Hello, I'm Winston. I lead interdisciplinary research that combines artificial intelligence, systems engineering, and urban analytics to advance integrated solutions for cities.
My PhD develops the concept of urban graphs and software for reproducible graph machine learning workflows to support more powerful and interpretable global scale urban analytics.
Now
Ezra Systems Postdoctoral Associate at Cornell University, mentored by Prof. Oliver Gao.
Recently
PhD in Urban Analytics at the NUS Urban Analytics Lab supervised by Prof. Filip Biljecki.
