I am a Lecturer in Statistics and Data Science in the School of Mathematics and Physics in
University of Queensland.
I previously held postdoc positions at QUT and UC Berkeley from 2015 to
2018, and at NUS from 2013 to 2014.
Before that, I earned my PhD in Computer Science from NUS, and completed
double first-class honors in Computer Science and Applied Mathematics, also from
NUS.
I am broadly interested in machine learning algorithms, theory, and applications.
I have published papers on topics including
sequential decision making under uncertainty,
weakly supervised learning,
probabilistic graphical models,
statistical learning theory, in venues such as NeurIPS, ICML, ICLR, UAI,
JAIR, JMLR.
I have received an IJCAI-JAIR Best Paper Prize in 2022, and a UAI Best Student
Paper Award in 2014.
I am seeking highly motivated students to work with me on machine learning
research.
If you are interested, please email me your CV/transcripts, a sample of
your writing, and a brief description of your research interests.
