My research focuses on the extension of a rule-base high-level programming language, based on constraints and logic, and its application in reasoning over stream data.

I have been working at the IMDEA Software Institute, under the supervision of Dr. Manuel Carro. We have designed and implemented a modular constraint system, Modular TCLP, and validated it with the integration of several constraint domains. We have used Modular TCLP to reimplement the state-of-the-art abstract interpreter PLAI increasing efficiency with shorter coding (1/3 of the previous version). We then sketched out how to apply TCLP to stream data analysis and detected the need to capture non-monotonic reasoning.

Since my stay at the University of Texas at Dallas in 2017, I have collaborated with them in the development of s(CASP), a novel non-monotonic reasoning system that integrates answer set programming and constraints. We have applied s(CASP) in several applications, e.g., to model and reason using event calculus.
