|| (but are you looking for the artist
Roma Devanbu ?)
am delighted to serve onthe Ed board of
the Wiley Journal of Software Maintenance and Evolution,
Research and Practice . Previously, I served my time on the
Ed board of several journals, including:
The Empirical Software Engineering Journal. (Springer),
IEEE Transactions on Software Engineering and the
ACM Transactions on Software Engineering and Methodology
If asked, I'm willing to help with the editorial work on The Wall Street Journal
(I think they need me).
ACM SIGSOFT FSE in 2006 in Portland, OR;
I co-chaired the program for
ICSE 2010 in Cape Town, with
Seb Uchitel. Check out
for ever-increasing software engineering fabulousness.

My Academic Lineage is the same as
William Cohen's , and
extends back to such luminaries as Maxwell,
Newton, Bernoulli, Poisson, Euler, and Leibniz. Those guys were smart, but
didn't wear bike helmets. Look what happened to them. Where are they now, HAH?
HAH? HAH?. Let that be a lesson.

I started off in Industrial software development,
then I worked at
Bell Labs, first in software development and then in research, at
Murray Hill, NJ; with the big travestyture, I went to AT&T Labs
Research in Florham Park. I have been at UC Davis since
late 1997. My undergraduate education was at IIT, Madras in India;
my doctoral work was done under Prof.
Borgida at Rutgers
University in the Garden
State, which is a
place, actually; although the Golden State
also has much to offer .

My spouse, Roma
Devanbu, is an artist and art educator whose work draws
on different cultures, and explores the interplay between the spiritual
and the temporal. Check out her work on her own web site , which
is really like a piece of cake for your eyes. .
In my "abundant" spare time, I worry a lot. About everything. e.g., my work, my
employer, fire, floods, war, bad guys, bad girls, financial derivatives,
the environment, and my kids. Not necessarily in that order. So
I need jokes in my life. So tell me jokes. Anytime, anywhere. Even bad ones.
If you are a foreign student interested in pursuing graduate studies at
UC Davis under my supervision, please a) look
over my papers, see if my research interests you b) apply for the
c) contact me when you're admitted. The bad news is that we
accept few foreign students. The good news is that your chances are
good if you're from
a reputed institution in your country,
or have publications in
international conferences/journals, or have very good scores on
GREs. etc. If you email me, use the following text in the
line: "Blue bottles with red stoppers are found in orange boxes".
