I hold a B.A. in Computer Science from New York University, and an M.S. and Ph.D. in Computer Science from the University of Wisconsin - Madison. At Wisconsin I worked with the Paradyn Performance Tools Group under the direction of Prof. Barton Miller; I was the recipient of a Wisconsin Foundation Fellowship and a NASA GSRP Fellowship.
My research is in diagnosing and characterizing the runtime performance of large-scale systems and applications. This includes power, cooling, and security as well as more traditional aspects such as execution time. My particular focus is on a holistic view that includes performance factors external to the application under study, such as resource contention, power constraints, OS interference, and the overhead of security mechanisms. I have focused quite a bit on HPC applications, and more recently on commercial server environments. I have collaborated with scientists at Lawrence Livermore National Laboratory, Pacific Northwest National Laboratory, San Diego Supercomputer Center, and New Mexico Consortium.
I teach graduate and undergraduate courses in operating systems, and also a variety of advanced courses related to performance evaluation of high end systems, for example, Introduction to Performance Measurement, Modeling and Analysis.
I represent the Maseeh College as PSU Faculty Senator. I serve the University as co-Chair of the PSU Committee on Committees, and as a member of the PSU Intercollegiate Athletics Board.
