Low-code Requirements Engineering

I've managed a team of 3 members studying tool support for behavior-driven development (BDD).

The goal of the project was to provide a low-code solution to produce Gherkin scenarios allowing non-technical stakeholders to participate in product behavior specification and review while directly interacting with the MVP.

My team has also studied how our tool solution would improve the traceability between requirements and the actual implementation code within different stages of the SDLC.

Code Commenting Quality

I have been a member of two teams analyzing source code documentation quality from different perspectives.

In one of the projects I co-managed a collaboration of 6 people performing a literature review of the academic publications of the last decade on comment quality assessment.

In another project our team was studying whether software developers actually follow commenting guidelines, and which guidelines are more confusing than helpful in producing quality project documentaiton.

NLP for Comment Inconsistency Detection

I have been working on two different projects on detecting comments inconsistent with the source code. Both use a combination of NLP and program analysis for it.

[upDoc] In the first project I was leading tool development for automatically detecting outdated comments during code change. At the moment the initial prototype, implementing the code-comment mapping tool component, is available on GitHub, and the full implementation with automatic change extraction and analysis is coming in June 2022!

[RepliComment] In the second project I worked in a team focused on detecting cloned comments and discerning between valid copies and those that are resulting in misleading documentation. The original RepliComment implementation, detecting comment clones, is available on GitHub, and there is also a dedicated repository for the upDoc+RepliComment pipeline that allows to classify the detected clones.

Runtime Program Verification

My research in this area focused on specification-based software verification in dynamic programming languages:

• how to write specifications of program behavior - expanding the formal specification language of program assertions/contracts to include new properties
• how to check these specs - translating formal contracts into checkable code snippets
• and how to do this efficiently - decreasing the run-time overhead added by the checks without compromising the program behavior safety and correctness guarantees

Most of the ideas were prototyped and tested in Ciao and its dedicated tools (see the GitHub mirror).
