I'm an Assistant Professor* in the Systems and Computing Department at the Federal University of Campina Grande (UFCG/Brazil). I gained a Ph.D. from the School of Computing at the University of Leeds (United Kingdom). I hold M.Sc. and a B.Sc. degrees from the Systems and Computing Department at UFCG.
I'm currently the department head of the undergraduate program in computer science. My research interests include topics in data modelling, knowledge representation, information retrieval, handling of conceptual vagueness, and user-aware/context-aware systems. I'm particularly interested in spatial and spatio-temporal information: modelling geospatial semantics; event/process modelling; Geographic Information Retrieval (GIR); and Volunteered Geographic Information (VGI).

* "Professor Adjunto" in the Brazilian Academic Rank, equivalent to Assistant Professor in the US Academic Rank, or equivalent to a Lecturer in the UK Academic Rank.
