Recent news

  • Aug. 23: I have joined the EECS Department at the University of Toledo as an assistant professor. I have openings for several PhD students interested in human dynamics and data analytics. My current focus areas involve the analysis of social network data and data collected from wearable sensors. Please email me if you are interested in joining my research group.
  • Jul. 12: Added slides from my recent talk at ICML 2015.
  • May 19: Our paper "Consistent estimation of dynamic and multi-layer block models" has been accepted to ICML 2015. A preprint is available on arXiv.
  • May 19: Added slides from my recent talk at AISTATS 2015.
  • Mar. 28: The SBP 2015 proceedings, which I co-edited, are now available. SBP is co-locating once again this year with BRiMS. The program looks very exciting this year!
  • Jan. 23: Updated Dynamic stochastic block models MATLAB toolbox to version 0.2.
  • Jan. 14: Added Dynamic stochastic block models MATLAB toolbox accompanying our 2014 JSTSP paper
  • Jan. 10: My paper "Stochastic block transition models for dynamic networks" has been accepted for oral presentation at AISTATS 2015. A preprint is available on arXiv.

Research

My main research interests are in statistical signal processing and machine learning with applications to network science and human dynamics. Current interests include development of statistical models and computational methods for analyzing time-dependent data in various forms including dynamic social networks and data collected from wearable sensors.
