Research Interests

My PhD research focuses on the development of non-parametric Bayesian methods (e.g., Pitman-Yor processes) for Structured Topic Modeling. I am also interested in Nature Langauge Processing (NLP), Information Retrieval (IR), Sentiment Analysis, Data Mining (includes text mining), especially by utilizing topic modelling.
