Research interests

Currently I have three aspects of research interest:

  1. The generalisability and clinical utility of traditional statistical risk prediction model and how could we improve its performance on individual level. Mainly with Cardiovascular disease as exemplar.
  2. The clinical implementation of machine learning (AI) models for risk prediction modelling and how could we take advantage of the strength of machine learning models and walk around from their disadvantages.
  3. The drivers of antibiotics over-prescription including what are the main drivers of antibiotic prescription, how could we best decrease the antibiotic prescription and any other impact of these interventions on antibiotic prescribing.

Methodological knowledge


I am experienced using EHR data to assess model performance on both population level and individual level of risk prediction model. I am also familiar with using risk prediction model and other statistics to conduct epidemiology studies, e.g. to investigate on the drivers of antibiotics over prescription.  


I am capable of combining the strength of different program languages (SAS, R, Python, C++ and Java), and quickly overcoming computational challenges of substantive software and hardware in the research. I am familiar with statistical programming with SAS procedures, model fitting with R packages and machine learning model fitting and validation with Python.


As an experienced data scientist, I am very familiar with conducting analysis with large data. I have fitted and validated multiple risk prediction models including both of traditional statistical models and machine learning models in a 3.6 million cohort. I designed a workflow with the combination of advantages of different programming languages to conduct efficient statistical analysis using large data.

Other research

I am also a part-time video editor and photo designer with an aim to make the educational course contents more interesting with meme, animation and comics.

I am also interested in independent game develop with Python. I wish to involve more educational video game into education.
