Welcome to my home page.
I was a faculty member at UCSD between 1987 and 2025, and am now retired.
My
research
is
in
operating systems, distributed systems and networks,
broadly
focusing on performance, reliability and security of Internet-scale
systems with highly decentralized control.
I also
primarily teach
our core courses on operating systems
(at both graduate and undergraduate levels).
Beyond computer science,
I
lead
a
summer study-abroad program
in Rome, Italy,
where we
study
the
architectural geometry and structural engineering
of classical
Roman monuments.

... What do you think the real University is? ...
The real University, [Phaedrus] said, has no specific location.
It owns no property, pays no salaries and receives no material dues.
The real University is a state of mind.
It is that great heritage of rational thought that has been brought
down to us through the centuries and which does not exist at
any specific location.
It's a state of mind which is regenerated throughout the centuries
by a body of people who traditionally carry the title of professor,
but even that title is not part of the real University.
The real University is nothing less than the continuing
body of reason itself.
from Zen and the Art of Motorcycle Maintenance, by Robert Pirsig
