Research Interests

My goal is to establish a research program in large scale statistical machine learning, data mining, signal processing, compressed sensing, estimation, and the interaction between computational software and mathematics. My main areas of application include anomaly detection, cyber-warfare, and network analysis, with a secondary focus on chemical sensor fusion and analysis of geo-spatial data.
