I am currently the Machine Learning Task Manager and Senior Research Scientist at USRA working in the Data Sciences group at NASA Ames Research Center, California. Most of my current research effort is directed towards developing large scale data mining and machine learning algorithms to solve problems in the earth sciences, aviation safety, computational sustainability, and graph structure analysis.
I graduated with a PhD in Computer Science from University of Maryland Baltimore County in 2009. My PhD research, guided by Dr. Hillol Kargupta, focused on developing a game-theoretic framework for privacy preserving distributed data mining.
My research interests include
- Anomaly detection and explanation in multivariate time series
- Spatio-temporal modeling for dependency and causal analysis
- Parallel and distributed algorithms
- Graph structure mining for anomaly detection and localization
- Sparse learning for terascale/petascale data sets
