I am a Senior System Scientist faculty member at Carnegie Mellon
University working in the Parallel Data Lab (PDL). I joined PDL
in December, 2003. My research interests is in building new systems
that are both novel and have potential to make a positive impact on
the world. As a Systems Scientist, my role in PDL is to work with
other faculty members to help architect, prototype, and deploy large
scale storage systems projects based on PDL research. I also play
a key role in defining the architecture of the PDL lab computing
environment, including the data center we have built on the first
floor of the CIC building. I am currently working with professors
George Amvrosiadis
and Greg Ganger on
storage in High Performance Computing (HPC) systems. I also worked
with Garth Gibson before he left CMU and returned to Canada to head
the Vector Institute for Artificial Intelligence. Prior to joining PDL, I was on the technical staff at AT&T Labs-Research for five years. At AT&T I worked on research projects relating to network monitoring, network content distribution, packet telephony, and "system on a chip" embedded devices. I have a doctorate in Computer Science from Washington University in St. Louis, Missouri. As part of my graduate research I wrote the UVM Virtual Memory system. UVM is in worldwide use as part of the kernel of the NetBSD and OpenBSD open-source operating systems projects.

Shane Zachary Cranor is our son. He was born in 2001. Shane likes music (both playing it and recording/producing it), photography, making videos, computers, frisbee, and eating gourmet food. Watch Shane's high school band "The Electric Army" perform their song "Heavy Dreamer" at a street festival here (Shane is the bass player), and check out Shane's soundcloud here.
Maya Quinn Cranor is our older daughter, born in 2003. Maya likes reading fiction, Dr. Who (both the old and new series), building robots with the Girls of Steel team, STEM, writing, Voltron (the animated series), editing her school's yearbook, playing both flute and soccer, hiking, mock trial, broadway musicals, and baking desserts.
Nina Veronica Cranor is our younger daughter, born in 2006. Nina likes to sing, play her electric guitar and electric bass, play role playing games (DND and Magic the Gathering), read scifi books, watch Dr. Who, play soccer, do STEM-related activities, and get dressed up and go out to a nice dinner. Nina is also a big fan of summer art camps of all types.
My wife and I have also done many home renovations projects. When we lived in New Jersey we bought a new house that was still under construction. A few years later we had the basement of that house fully finished. In Pittsburgh, we have a house that is over 100 years old and we have done many upgrades including fun stuff like a full kitchen and full bathroom renovation, to less fun stuff like replacing "tube and knob" electric wiring with modern wiring and having the concrete floor of our basement dug up to replace decaying cast iron sewer pipes.
When my kids started taking an interest in making music, I took up learning the electric guitar first using the internet (Justin Sandercoe's youtube channel is a great resource) and later I started taking lessons at our local music school (Sunburst School of Music in Squirrel Hill). The guitar is an endless source of fun and challenges and a great change of pace after working on computer stuff all day at work. I like to find interesting songs and reverse engineer them by transcribing the parts by ear (I use a program called "Transcribe!" to help with this). I especially love to perform some of the songs I've figured out and arranged with our friends+family band "Unanticipated Fun." We've done songs from a wide variety of artists (anything from The Monkees to Tool).
