Biography

Xiancheng Li is a post-doctoral researcher, currently working with Professor Pietro Panzarasa and Dr. Anna de Simoni. He works in the AD HOC program (https://www.qmul.ac.uk/adhoc/), which aims to help people with troublesome asthma to better control their symptoms and improve their quality of life, by engaging with other people with asthma in an online community.

Before joining AD HOC team, Xiancheng Li was completing his PhD in the Centre for Globalisation Research at the School of Business and Management, Queen Mary University of London. His doctoral research focused on academic collaborations and innovation, applying a combination of network science, machine learning, and econometric methods. In particular, he investigated how key decisions made by scientists throughout their careers can influence their long-term success.

Teaching 

  • Teaching Associate, Machine Learning and Digital Technology, 2023-2024 and 2024-2025
  • Teaching Associate, Social Network Analysis, 2020

Research Interests

Xiancheng’s research interests currently centre around discovering the network patterns of users’ engagement in online health communities and evaluating the correlation between network properties and users’ health-related outcomes. He is also interested in applying natural language processing to provide an in-depth understanding of the evolution of essential themes, keywords and topics discussed in communities.
