Research interests

Currently, I am interested in social network analysis, in both the connectivity side and the content side. My interests include: analysing popular content on social media and communication-style studies. I am also interested in spatial-temporal social networks, Snapchat specifically. On the content-front, I am interested in Emojis analysis and prediction on social media (utilising NLP techniques). I am also interested in learning to rank approaches to content retrieval and ranking, which is a machine learning approach for information retrieval.
