Summary
I am a Lecturer in Statistics in the Department of Mathematics at Imperial College London (roughly equivalent to Assistant Professor). My main research interests are broadly based on statistical analysis of dynamic networks. In my work, I enjoy exploring an array of different statistical techniques, adapted and extended to dynamic network modelling, such as latent variable models and model-based clustering. In recent years, I have also developed an interest for statistical analysis of event-time data, topic modelling, Bayesian non-parametric methods, and recommender systems. My research has been mainly applied to statistical cyber-security problems, but also to social networks, music streaming services, and bike sharing systems.
For further details, see my personal webpage.
I am always interested in hearing from potential PhD students. If you think that your interests and background are a good match with my research, please contact me.
