Research Interests

I'm interested in Data Mining, Signal Processing & Optimization Algorithms for Data Mining and Multi-way (Tensor) Analysis, as well Coupled Matrix-Tensor Analysis. More specifically, I'm currently interested in discovering how knowledge and information is expressed and stored in the brain, through analyzing brain scan data (possibly from diverse experiments), coupled with external information. Additionally, I'm also interested in anomaly detection on very large graphs, especially when temporal or multi-view information is present.
