Networks and Learning

Our research lies in both basic and applied areas of networks, machine learning, and large-scale data analytics. We study fundamental issues and derive engineering solutions for modeling and managing heterogeneous large networks; develop learning algorithms; analyze and learn knowledge from large-scale data.


Two postdoc positions available starting Fall 2018/Spring 2019 (here)

Abstract: … we analyse data from four major service regions representing Upstate New York during Super Storm Sandy and daily operations. Using non-stationary spatiotemporal random processes that relate infrastructural failures to recoveries and cost, our data analysis shows that local power failures have a disproportionally large non-local impact on people …
