Areas of Interest
- Operating systems
- Computer networks & wireless networks
- Distributed systems
- File systems
While my primary focus at present is on teaching,
I am interested in working with students on projects
in the following areas:
- Automatic configuration of link-level retransmission
- Peer-to-peer file system architecture
- Distributed operating system structure (mostly
in the context of Plan 9).

In May of 2002 I defended my Ph.D. dissertation,
An Internet-style Approach to Managing Wireless Link Errors.
Briefly, I investigated some of what must be done
to extend the "Internet experience" across
error-prone wireless links.
In particular, I argued that protocol-blind link-level
adaptive error control is the right solution for bursty
I then proposed a new notion of fairness for flows
traversing noisy links,
effort-limited fairness (ELF),
which ensures sensible outcomes in response to
link capacity loss.
Evaluation was based on replaying bit-level error traces
past a prototype implementation running in a
Many moons ago,
