I am an Associate Professor of Computer Science at Carleton College. I have been a member of the Carleton faculty since September 2003. Prior to Carleton, I worked as a post-doctoral researcher at Hewlett Packard Laboratories from 2000-2003. I have a PhD and an MS in Electrical Engineering from Northwestern University and a BS in Electrical Engineering from the University of Notre Dame.

My research interests include quality of service/quality of experience of Internet applications; self-healing networks; streaming media; network measurement; performance analysis of computer and communication networks; and queueing theory. I focus on the intersection of application performance and network performance, determining how the two interact with and react in the presence of each other. Currently, I'm interested in self-healing networks: specifically, how do we design networks that can detect potential future quality degradations in application performance and mitigate such degradations before they occur? I'm most interested in self-healing networks for media-rich applications such as high-quality video on demand, distance learning, and remote medicine. For more information, see my research page.

I teach courses in Computer Networks, Computer Architecture, and our Intro course sequence. I've also taught and developed courses on Computer Security, Digital Storytelling, Peer-to-Peer and Multimedia Computing, and a dyad on human-centered computing (with the Psychology department). In addition, I typically advise our Senior Comprehensive Exercise ("Comps"). For more information, see my teaching page.

I currently serve on CRA-E, the Computing Research Association's Education Committee, where we are studying the pipeline from undergraduate to graduate study in US institutions. I'm also co-leading the recruitment and engagement project team of the National Center for Women in Information Technology's (NCWIT) Academic Alliance. I formerly coordinated the Clare Boothe Luce Scholars program at Carleton, a program aimed at developing a cohort of research student-scholars in Physics, Astronomy, and Computer Science. Outside of academia, I volunteer for my alma mater's alumni schools committee, participating in recruiting events for area prospective students.
