My current CV
The most recent copy of my CV is
available here.
I am on sabbatical in academic year 2012/13. The best way to get in
touch with me is by e-mail.
Previous semesters (with links to
the course pages).
If you have any
questions about any of these courses, please don't hesitate to send me
an e-mail or stop by.
My research is in the area of semantics of programming languages and
program optimization. Publications and reports
are posted here (see below) as they become
available. Questions, comments, and suggestions are welcome!

I am interested in any topic related to programming languages,
software design,
and compilers research, as well as topics in cryptography and its
applications and in computational linguistics. Other topics are fine
as well. Below are some random ideas:
- Java decompilation: restoring Java source code from byte
code. This topic is a nice combination of technical research
and discussion of ethical issues (protection of intellectual
property).
- Incorporating program performance considerations into a software
development cycle, specifically into agile development.
.
I am originally from Moscow, Russia.
I spent many years in Boston. I received my Ph.D. at Boston University in Spring 2002. From
Fall 2001 till Spring 2003 I taught at Computer Science Department at
Wellesley College. Click here to see my web page
at Wellesley.
