Hi everyone! I am a Ph.D. candidate under the supervision of Dr. Andrew Crooks in the Department of Geography at the University at Buffalo. My research focuses on critically understanding urban space by leveraging (geo)computational techniques and data informatics. I am interested in Space and Place, Urban Perception, Agent-Based Modeling, Spatial Analysis and Visualization, Social Media and Big Data. I received a M.S. in Physics from National University of Singapore and B.S. in Physics from Minjiang University of China. Prior to starting my PhD, I worked as a Research Associate in the Singapore University of Technology and Design (SUTD) and as a Research Engineer in the Singapore-MIT Alliance for Research and Technology Centre (SMART).

The recent COVID-19 pandemic has brought the debate around vaccinations to the forefront of public discussion. In this discussion, various social media platforms have a key role. While this has long been recognized, the way by which the public assigns attention to such topics remains largely unknown.
Analyses of urban spaces have often stressed the importance of both the density and diversity of the people they attract. However, the diversity of people is a challenging concept to operationalize within the context of urban spaces, which is why many evaluations of urban space have relied primarily on density-based measures.
The COVID-19 virus has caused and continues to cause unprecedented impacts on the life trajectories of millions of people globally. Recently, to combat the transmission of the virus, vaccination campaigns around the world have become prevalent.
With progressively increased people living in cities, and lately the global COVID-19 outbreak, human mobility within cities has changed. Coinciding with this change, is the recent uptake of the ‘15-Minute City’ idea in urban planning around the world.
Traditional approaches to human mobility analysis in Geography often rely on census or survey data that is resource-intensive to collect and often has a limited spatio-temporal scope. The advent of new technologies (e.
Identifying meaningful locations, such as home or work, from human mobility data has become an increasingly common prerequisite for geographic research. Although location-based services (LBS) and other mobile technology have rapidly grown in recent years, it can be challenging to infer meaningful places from such data, which – compared to conventional datasets – can be devoid of context.
The ‘New Urban Kampung’ is a S$6-million interdisciplinary research program with team members from architecture, humanities, and engineering pillars. This research aims to develop new strategies and platforms to enable public housing estates to become vibrant collaborative communities, replicating the spirit of the old ‘kampung’ (village) with their strong community care and resilience.
