Research overview

I am interested in nonparametric methods for complex network data types, and their application to inference tasks, such as predicting missing links in the network. Nonparametric methods, also known as `assumption free' methods do not assume a specific parametric form for the underlying data generating process and are hence more suitable for large volumes of complex observations. One of the core themes of my research is
to develop network analogues of classical statistical tools, from local linear estimation of structure in networks to bootstrapping techniques and dependence measures for multi-layer networks.
