My Research

I received my Ph.D. in statistics from Rutgers University in 2000. I joined the Data Analysis Research Department of Avaya Labs in July 2000. My dissertation was about profiling UNIX users and processes with applications to computer intrusion detection. My research interests include data mining, visualization, and statistical computing.
