It was on Wednesday 10th of June that the first international PhD student accepted in Han’s laboratory passed her defense, online, in front of a jury of six – Professor Haoying Han among them – and graduated successfully.
Vivian’s research journey in China started in 2016 with Urban Public Spaces and Sustainable Development as her focus of interest. During 2018 and 2019 she published three articles in collaboration with Prof. Han, Noman Sahito a member of our lab and Tram Ngoc Lam a Vietnamese researcher whose research interests fall into media and Asian culture and societies. Her papers focused on Urban Public Spaces, more specifically “third places” and sociable places, debating their role in promoting Sustainable Development.
Having met the graduation’s requirements of Zhejiang University, she presented the culmination of her work one month prior to her expected graduation date, as a cross-sectional study in Ho Chi Minh City and Hangzhou on Public Space and Urban Vibrancy.
With the commercial-related public spaces emerging as the new civic centres and social hubs in contemporary cities, Vivian decided to focus her study on bookstore-cafés and streets activities as a new form of UPS (Urban Public Spaces) and presented them as a place for socializing and information sharing.
She used social networks data to assess their role in promoting Urban Vibrancy and ranked the Vibrancy of each of her study cases relying on four indicators, namely: Density, Livability, Accessibility and Diversity.
She characterized and mapped the dynamic urban vibrancy related to UPSs in Hangzhou and Ho Chi Minh City using several computing tools and found that in both cities human activities decline from the city core to its periphery. However Hangzhou’s pattern was more polycentric than Ho Chi Minh City’s pattern which looked more scattered.

As she observed a monocentric spatial pattern of urban vibrancy in the two cities (vibrant community neighbourhoods with private public spaces and open spaces at walking distance of transportation), she evaluated the effect of urban street centrality on the studied UPS revealing a positive relationship between the two of them.
Her research findings also suggested a comprehensive understanding of street design and management to promote their social role.
We congratulate Dr. Nguyen for her achievements and wish her the best for her new journey and future research!
