Personal Statement

I currently own and operate Dabeaz LLC, a consulting company that primarily focuses on the development and use of open-source software development tools. I am the creator of several well known programming libraries and also offer professional training on the use of dynamic programming languages such as Python. From time to time, I also offer technical consulting related to software engineering, systems analysis, and reverse engineering.

Career Highlights

• Supercomputing
  At Los Alamos National Laboratory, I developed applications software, algorithms, and programming techniques for massively parallel supercomputing systems including the Connection Machine 5 and Cray T3D. In 1992, I was the primary developer and architect of SPaSM (Scalable Parallel Short-range Molecular dynamics), a software package for performing experiments in materials science (crack propagation, fracture, dislocations, etc.). In 1993, SPaSM was one of the winners of the IEEE Gordon Bell Prize competition in high performance computing. In 1995, I helped pioneer the use of scripting languages with parallel supercomputers and in 1996, I was the first developer to port the Python programming language to such machines. The use of scripting languages were an instrumental part of a massively parallel data-analysis and data visualization system I built for remote exploration of multi-gigabyte datasets. I presented this work at a variety of international conferences including IEEE Supercomputing, the International Parallel Processing Symposium (IPPS), and the SIAM conference on parallel processing.

• Programming Language Interoperability
  In 1996, I created a popular open source programming tool called SWIG (Simplified Wrapper and Interface Generator) that automatically binds existing C/C++ software to a wide variety of other programming languages including Perl, Python, Tcl, Ruby, Java, C#, PHP, Scheme, Ocaml, and many others. SWIG works by reading C++ header files and automatically generating language bindings. To handle the complexities of C++, SWIG implements the C++ type system and supports most language features including templates, namespaces, and operator overloading. SWIG has been downloaded by tens of thousands of programmers and is in widespread use. For instance, SWIG is one of the core technologies used to develop software at Google. It is also used by many government laboratories including Los Alamos National Laboratory, Lawrence Livermore National Laboratory, and Argonne National Laboratory. SWIG is currently maintained by a team of developers from around the world. More information is available at www.swig.org.

• Software Development Tools
  In 2000, I created a mixed-language debugging system called WAD (Wrapped Application Debugger), that allows programmers to easily debug applications written in a mix of different programming languages (e.g., C++ mixed with Python). WAD is unique in its approach to this problem and a paper on the topic was awarded "Best Paper" at the 9th International Python Conference. In 2001, I created a Python implementation of the popular lex/yacc parsing tools called PLY (Python Lex-Yacc). PLY is used by programmers to implement parsers, interpreters, and compilers. In 2002, I released an embedded webserver library that allows programmers to add web-based remote monitoring and diagonistic features to C/C++ software. A paper on this library, co-authored with Sotiria Lampoudi, won "Best Student Paper" at the 2002 USENIX Freenix conference.

• Computer Graphics and Data Visualization
  I have written three separate graphics libraries. In 1986, I developed a 3D mathematical plotting library (written in 6502 assembler) for the Apple 2. In 1990, I wrote a high-performance graphics and animation library for the IBM PC. This library, implemented entirely in 8086 assembly language, allowed programmers to access SVGA graphics cards from programs written in the Modula-2 programming language. In 1995, I implemented a three-dimensional graphics library and visualization system for massively parallel supercomputers. This system allowed scientists to remotely analyze large-scale data sets consisting of hundreds of gigabytes of data.

• Computer Architecture
  I am familiar with the principles of computer hardware, systems design, and low-level programming. I have written two major software packages (graphics libraries) entirely in assembly language, both of which directly controlled the underlying graphics hardware. On the Connection Machine 5, I implemented numerical integration kernels in assembly language in order to control special-purpose vector co-processors. In a related project, I later showed that the optimizations achieved using special purpose hardware (the vector coprocessors) could also be achieved by carefully optimizing code for the SPARC RISC processor instead. My work in compilers and debuggers has also required a detailed knowledge of the underlying computer architecture. Moreover, as a professor, I taught courses in operating system design that focus on the connection between computer hardware and systems software. As a graduate student, I was awarded the college of engineering teaching award for my work as an assistant in the undergraduate computer architecture and digital logic design courses.

• Computational Physics
  At Los Alamos, I worked as a computer scientist in the Theoretical Physics division and Center for Nonlinear Studies (CNLS). In this position, I worked with physicists to develop software for solving a variety of scientific problems. In 1991, I worked on software for solving stochastic ordinary differential equations. This software was used to study structural phase transitions in materials. In 1992, I started working on molecular dynamics simulation software. This software was used to study problems in materials science including fracture, crack propagation, and dislocation dynamics. Although my primary focus was software, I was actively involved in all aspects of collaborative research that led to publications in Science and Physical Review Letters.

• Book Author
  In 1999, I wrote "The Python Essential Reference", a comprehensive reference for the Python programming language. The Essential Reference is one of the most highly regarded books on this topic and is available in Japanese, Chinese, Russian, Polish, and German translation. In 2001, I contributed three chapters on XML to the book "Python Web Programming" by Steve Holden. A 3rd Edition of the "Python Essential Reference" was published in 2006. I am currently working on the 4th Edition to be published in 2009.

• Software Analysis Consulting
  Since 2003, I have occassionally worked as an independent technical expert on legal cases involving copyrights and patents. This work has involved a considerable amount of software analysis, including the analysis of two large C++ systems each involving more than 500,000 lines of source code. I have also analyzed more than a dozen smaller systems involving source code for embedded devices and controllers. In the course of my analysis work, I have been called upon to examine software written over a 35-year time span. This software has been written in a variety of programming languages including assembly language, Pascal, PL/M86, C, C++, Visual Basic, and Java. In addition the software has involved the use of custom-written operating systems as well as many commercial systems including Windows-NT, Windows-CE, Linux, OS/2, pSOS, QNX, iRMX, and AMX. In the course of analysis, I often must deal with all aspects of the software from high-level distributed systems (e.g., CORBA, COM) to direct control of specialized hardware devices. A significant portion of my analysis work has also involved software forensics. For example, matching undocumented software to specific versions of hardware devices, uncovering technical specifications, and working with software version histories.

• University Professor
  At the University of Chicago, I was a tenure-track assistant professor where I taught graduate courses in Operating Systems, Networks, and Compilers.
