Research



I am interested in using statistical and computational principles for studying relational data in social computing.

Two types of commonly appearing data sets in social applications are:

  I) Undirected weighted networks: We develop Graphlet decomposition for matrices with scalable/interpretable inference.

  II) Directed relations among alternatives: We develop scalable methods for rank aggregation and social choice using random utility theory.
