I'm an associate professor at the University of New Mexico in the Department of Computer Science. I did my undergraduate work at Mississippi State University and received my Ph.D. from the University of Arizona in December of 2002. My research interest broadly cover operating systems and networks particularly, scaling, composition, and adaptation issues in large-scale systems, and I work with collaborators at Sandia, Los Alamos, and Lawrence Berkeley National Laboratories, IBM Research, AT&T Research, and a variety of universities. Outside of work, I have a wonderful family and a range of hobbies that occupy my spare time.
My research is broadly concerned with operating systems and networking. In particular, I'm interested in system software for large-scale systems, including multi-core, supercomputing, and high-performances networked systems. I maintain research webpages on that list my research interests and projects, publications and invited talks, and current and former students. I also maintain a page of information for prospective students that you should read if you're interested in working with me. A few key recent papers are listed below.

If you need to contact me, email is generally the best way. For face-to-face meetings, I'm available during my office hours or by appointment. My office is in 301B in the Farris Engineering Center. In general, I'm happy to meet with students at any time I'm available; if you want to meet, view my calendar, pick a time that is free, and suggest it via email.
If you insist on more old-fashioned means of contacting me, my phone number is 505-277-3032 and my fax number is 505-277-6927. For regular mail, my mail address is:
Patrick G. Bridges MSC01-1130 1 The University of New Mexico Albuquerque, NM 87131-0001
If you need to use a physical mailing address (i.e., for UPS), use:
Patrick G. Bridges Department of Computer Science University of New Mexico Farris Engineering Center #157 Albuquerque, NM 87131
Outside of work, I spend much of my time with my wife Terese, my son Will, and my daughter Elena. Terese and I met in graduate school at the University of Arizona, from which Terese received a Master's degree in Bilingual education and a Ph.D. from the Department of Language, Reading, and Culture. Her Ph.D. research focused on student teachers, particularly in how the language experiences of bilingual student teachers effect their teaching. She currently teaches full time at Zia Elementary School in Albuquerque. Occasionally Terese and I visit Guatemala, where Terese lived for a number of years before we met.
Will was born on February 15, 2002, not long after we moved to Albuqueruque, and Elena was born on December 7, 2006. They both happily take up much of our time. Newer pictures of William and Elena are on Terese's page, and some older pictures, mostly of Will, are on my .Mac pictures page. We regularly attend St. Michael and All Angels Episcopal Church in Albuqueruque, a thoughtful, welcoming, progressive church.
Outside of work and family, I have a number of different hobbies that occupy some of my time. For example, I'm an avid Go player and a (weak - AGA 2k or so) student of Alexandre Dinerstein 1p, as well as a volunteer admin on the KGS Go Server. For outdoor activities, I'm a casual tennis player and skier, and I do a decent amount of cycling now and again, too. I enjoy a friendly or low-limit cash game of poker now and again, too. Finally, I like to cook, primarily southern/cajun and southwestern food, and have a recipe page that I occasionally edit. New Mexico is a great place to be for all of these hobbies.
Despite growing up in largely-conservative Mississippi, I'm an unabashed liberal, though in the more classical, positive liberalism (think John Stuart Mill) sense of the word as opposed to the prejorative sense of the word. This means I fully support all of the amendments to the constitution, particularly including free speech, the separation of Church and State, and the right to bear arms. I also support progressive social policy (for example strong public education, head start, and the social safety net) to the extent that it is economically feasible. In particular, I believe that the long term moral and economic costs of not supporting such policies (e.g. increased prison population, poorly-educated workers and voters) are greater than the short-term cost of supporting them. A friend of mine once referred to me as a bleeding-heart libertarian, and I can't exactly deny that somewhat strange characterization.
As a side note, I've spent some time trying to figure out New Mexico's School Grading Formula.
