About me
I teach several CS subjects at the Escola Tècnica Superior d'Enginyeria Informàtica (ETSINF) and at the Department DSIC (within the Master's program in Software systems engineering and technology), UPV. My current homepage: https://gvidal.webs.upv.es/
My research focuses on the areas of programming languages, artificial intelligence and software engineering, combining both theoretical developments and practical applications. I am a member of the VRAIN research institute, where I lead the MiST group on multi-paradigm software technology.
We often have positions available for graduate students interested
in pursuing a PhD or Master's degree. Check the topics below and

I'm mostly interested in the following research areas:
- Declarative formalisms, which are known for their higher level of abstraction. They can be considered both as specification languages and, often, as programming languages. Among others, we consider term rewriting, logic programming (Prolog), functional programming (e.g., Haskell), and the actor model (e.g., Erlang).
- Symbolic artificial intelligence. Symbolic AI typically uses some form of logic for knowledge representation, learning, and inference. In this context, we focus on logic programming languages like Prolog or Datalog, and their probabilistic extensions (e.g., ProbLog), as well as their application in the context of interpretable and explainable AI (XAI).
- Reversible computation. Besides its theoretical interest, reversible computation is a fundamental concept that is relevant in many different areas like cellular automata, bidirectional program transformation, or quantum computing, to name a few. In particular, we have defined a reversible semantics for the message-passing concurrent language Erlang in order to design a causal consistent reversible debugger, to improve fault-tolerance, etc.
- Software verification, testing and debugging. Ensuring the reliability of critical software is one of the major challenges today. In our group, we consider different approaches, like formal verification (e.g., model checking) and software testing (e.g., concolic testing). We also consider reversible debugging of message-passing concurrent programming languages, as mentioned above.
- Static analysis and program transformation techniques. These techniques can be used for computing program properties as well as for improving its efficiency, readability, etc. Moreover, they have a rigorous mathematical foundation, which allows us to formally prove their correctness (and other useful properties).
