Monica Lam is a Professor in the Computer Science Department at
Stanford University since 1988. She received a B.Sc. from University
of British Columbia in 1980 and a Ph.D. in Computer Science from
Carnegie Mellon University in 1987. She is the Faculty Director of
the Stanford MobiSocial Computing Laboratory and a co-PI in the POMI (Programmable
Open Mobile Internet) 2020 project, which is an NSF Expedition started
in 2008. Her current research interests
are in building an open and federated social computing infrastructure.
She has worked in the areas of compiler optimization and software
analysis to improve security.
She is a co-author of the book Compilers, Principles, Techniques, and Tools
(2nd Edition), also known as the Dragon book. She and
her students started Mobisocial Inc. in 2012 whose goal is to create
an open social internet, where users can share anything while owning their data.
Monica is an ACM Fellow. She received an NSF Young Investigator
award in 1992, the ACM Most Influential Programming Language Design
and Implementation Paper Award in 2001, an ACM SIGSOFT Distinguished
Paper Award in 2002, and the ACM Programming Language Design and
Implementation Best Paper Award in 2004. She was the author of two of
the papers in "20 Years of PLDI--a Selection (1979-1999)", and one
paper in the "25 Years of the International Symposia on Computer
the ACM SIGPLAN Programming Languages Design and Implementation
Conference in 2000, served on the Editorial Board of ACM Transactions
on Computer Systems and numerous program committees for conferences on
languages and compilers (PLDI, POPL), operating systems (SOSP), and
computer architecture (ASPLOS, ISCA).
In the area of mobile and social computing, her group developed
Musubi, a message-based mobile social network that delivers both an
attractive user experience as well as distributed data ownership.
The paper on Musubi is a finalist of Best Student Paper in the WWW 2012
Her contributions in compiler optimizations include software pipelining,
data locality, parallelization. The SUIF compiler infrastructure
developed by her research group has been widely used by compiler
researchers all around the world.
Her contributions in program analysis for security include tools for
automatically detecting cross-site scripting and SQL injection bugs in
Java/JSP web applications, which was based on a novel
context-sensitive pointer alias analysis. Other contributions include
the bddbddb (BDD-based Deductive DataBase) analysis system, the PQL
program query language, the Diduce dynamic root-cause analyzer, the
Clouseau C++ memory leak detector, and the Cred buffer overrun
