Teaching and Advising

In Fall 2018 I am teaching EECS 590 Advanced Programming Languages. I welcome graduate and undergraduate students and community scholars. If you are an undergraduate student, note that currently only CSE graduate students can enroll directly, so you must use the override system. Note that many overrides are not be processed immediately.

Claire Le Goues, Zachary Fry and I have written an article explaining the CS job search process for graduate students (e.g., teaching and research statements, interviews, offers, negotations, academia and industry) and our experiences with it from 2005 to 2014.

Conferences and Workshops

I am co-organizing the Genetic Improvement Workshop, co-located with the 2018 International Conference on Software Engineering. I encourage you to submit interesting work!

Research Projects

My current main research interests relate to consciousness, time, and advancing software quality by using both static and dynamic programming language approaches. On the purely-CS side, I am particularly concerned with automatic or minimally-guided techniques that can scale and be applied easily to large, existing programs. I believe that finding bugs is insufficient, and I also work to help programmers address defects, understand programs, and program correctly.

Current major research interests and areas:

Medical Imaging, Consciousness and Time. I believe consciousness to be primal, relevant, inadequately explained, and amenable to experimentation: to me, it is the most interesting of the big problems. I believe the experience of consciousness over time to be a hard problem (in a sense akin to NP-Hard) in that solving it would allow us to solve most other problems. While these are not typically research problems considered in computer science, I believe they are becoming approachable through modern medical imaging and interested prospective students are encouraged to compare my thoughts on the subject to their own.

• Project and Dataset Webpage

Automated Program Repair. We have pioneered algorithms, such as GenProg, to synthesize repairs for defects in legacy programs using only standard testcases (no code annotations or formal specifications). We use special program representations and modification operators to search through the space of candidate patches until one is found that passes all of the testcases but does not demonstrate the error.

Program Analysis and Transformation. I enjoy designing, and applying, algorithms that analyze the semantics, behavior and maintainability of software. I particularly appreciate program analysis because it benefits from both formal, logical proofs as well human studies and natural language.
• Indicative Paper: Using Dynamic Analysis to Discover Polynomial and Array Invariants (distinguished paper award, ICSE 2012)

Improving Software Properties. Beyond functional correctness, a number of other properties are important to software. Aspects as diverse as power consumption, maintainability, and visual fidelity are all important in some domains. We have developed techniques to improve or trade-off these non-functional properties in software automatically.
