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.

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.
