I'm a 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 and information retrieval. 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).
