I am also interested in howwhole-program optimization affects language design: if it is assumedthat the compiler will have access to the entire program, then manycompromises made in existing language designs become unnecessary. Iam interested in applying the lessons learned in exploring wholeprogram optimization towards designing a new systems programminglanguage that is both flexible and efficient, based on an underlyingimplementation that does whole program analysis.<p>To validate my research, I have been one of the three principaldesigners and developers of Vortex, an optimizing compiler forobject-oriented languages. Vortex defines a language-independentintermediate language for object-oriented languages that ishigh-enough level to permit optimization of features such as messagesends, closures, and object creations. It also contains a unique wayof composing optimization passes so that they run in parallel,obtaining better results than repeatedly running the passesseparately. For example, the compiler applies intraprocedural classanalysis, profile-guided receiver class prediction, inlining, aliasanalysis, splitting, and CSE all at once, in a single combined pass.Part of the work on Vortex has been to develop ways of structuringoptimization passes to permit this kind of composition while stillallowing the passes to be developed largely independently of eachother. We have a nice framework for specifying iterative data flowanalyses that permits clients to develop new optimization passes withrelatively little effort (for example, the Vortex dead assignmentelimination pass is approximately 50 lines of code).</tr><tr><td align=middle><h2>Publications</h2></td><td>Some recent <!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><!WA20><a href="http://www.cs.washington.edu/homes/jdean/papers.html"> papers </a> I've authored or co-authored.<tr><td align=middle><h2>Personal</h2></td><td>I love <!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><!WA21><A HREF="http://www.netimages.com/~chile/">very spicy food</A> (as they say, "mild is a four letter word") and <!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><!WA22><A HREF="http://www.unm.edu/~madrigal/coke.html">Coke</A>.
