Networks are  widespread in technology, biology, and society. Moreover, they can encode similarity between arbitrary objects (i.e., images, videos, etc.) and thus play a crucial role for data-analysis methodology in general. I develop mathematical, statistical and machine learning tools to study network representations of complex systems and data. My work falls under two broad groups:

• Network-Data Analytics — methodology development for community detection, ranking systems, network inference, and manifold learning;
• Dynamics on and of Networks — nonlinear and stochastic systems including social contagions, oscillator synchronization, and network evolution.
  

Importantly, these two groups are closely intertwined. That is, realistic modeling of dynamical systems typically requires assimilation with empirical data. At the same, data-analysis methodology often stems from the study of dynamics. Random walks, for example, are central to algorithms including PageRank, Infomap, and Diffusion Map. I study network dynamics and network data as a synergistic pursuit.
