Research

The PASTA group conducts research on Program Analysis, Software Testing, and Applications thereof. We are not afraid of spaghetti code. We often use dynamic analysis and grey-box fuzzing to identify software bugs or achieve other software engineering objectives.

Our members have developed program analysis and automated testing techniques for various applications and domains, including:

• Classroom Programming Assignments
• Concurrent Asynchronous Programs
• Big Data Analytics
• Microservices
• Trusted Execution Enviroments
• Cyber-Physical Systems
• Smart Contracts
• Algorithmic Complexity
• Property-Based Testing

Our ongoing research targets several new challenges and domains including continuously evolving software, software-defined networks, and autonomous vehicles.

Ethos

Open Science

For science to make rapid and sustained progress, we believe that academic research should be made openly accessible, reproducible, and where artifacts exist, also directly reusable. To this end, we make the following commitments:

• We only publish in venues that are at least Green Open Access (e.g., conferences and journals that are run by USENIX, ACM, or IEEE).
• Upon publication of any research results, the corresponding artifacts and tools produced by our group will be made open-source and publicly available under a permissive license such as a Creative Commons or MIT License, as appropriate.
• For research involving quantitative empirical results, we will make every effort to release artifacts that facilitate independent reproduction or validation of those results (e.g., as a Docker container with a DOI).
• Where possible, we will participate in artifact evaluation.

Ethics

We also believe in being responsible members of society and in working towards scientific advancement for good, not evil. We implement this outlook in the following ways:

• As computing professionals, we adopt the ACM Code of Ethics and Professional Conduct.
• Our research is not funded by military agencies. (Why does this matter? See Ben Kuipers' excellent article on this subject.)
• In matters of computer security, we follow industry-standard responsible disclosure practices (e.g., as adopted by CERT or IETF).

Join Us

If our research and ethos are appealing to you, consider joining our group!

Prospective graduate students should apply to the Software Engineering PhD program at CMU.

Undergraduate students in the US can apply to the REUSE program to join our group for a summer.

If you are already enrolled in CMU as a student, send us an email from your Andrew address.

Alternatively, look out for one us at an ICSE.
