Profile

I’m currently a Lecturer in Predictive Analytics at the University of Edinburgh Business School. Before joining Edinburgh, I was a Lecturer in Computer Science at the University of Exeter. In the previous, I worked as a research fellow in the Department of Informatics, University of Sussex (UK) during the period 2017 - 2019, and as a postdoc in the Department of Computer Science, University of Exeter (UK) during the period 2019 - 2020.

My research interests focus on probabilistic machine modelling and non-parametric Bayesian predictive methods such as Gaussian Process and Student-t Process modelling. As their applications, I also have expertise in time series prediction, financial data analysis, algorithmic fairness and human mobility.

Currently, I am leading an online Research Interest Group on Gaussian Process Modelling (approx. 500 members till May 2021) and the topics include Bayesian non-parametric modelling, Bayesian optimisation, Bayesian inference, Bayesian computation and many related application areas.
