patrick m widener, ph.d.

I am no longer at UNM. I now work in Emory University's Center for Comprehensive Informatics as a Senior Research Scientist (and also Emory's new Department of Biomedical Informatics as Research Assistant Professor). I will be continuing my research on large-data systems and applications for high-performance computing and exploring new applications in medical informatics. I'm a Research Assistant Professor in the Department of Computer Science at the University of New Mexico. I collaborate with Patrick Bridges in the Scalable Systems Lab. At UNM, I'm working on systems software for high-performance I/O, configurable operating systems and lightweight file systems for high-performance computing. My core research interests are in metadata and data management, particularly data privacy, and how to describe, manage, and protect data efficiently at different levels in the application/operating system/hardware stack.

I received my Ph.D. in August 2005 from the College of Computing at the Georgia Institute of Technology. My dissertation advisor, Karsten Schwan, directs the Center for Experimental Research in Computer Systems (CERCS). My dissertation described a novel method of providing data protection in high-performance and pervasive applications, building on efficient data representation and data transport middleware developed at Georgia Tech.

See my research projects page for more information on the kinds of things I've been up to, or my calendar if I'm not where you thought I would be.
