Publications
I have published over 155 articles in their majority in top-tiered journals (ACM TODS, TWEB and Computing Surveys, IEEE TKDE, Springer Machine Learning Journal, Distributed and Parallel Databases and Internet Computing) and conferences (ACM SIGMOD, PODS and CIKM, IEEE ICDE, EDBT, ICDT ECAI, WWW)
My research work was driven by the need to manage, process and analyze post-relational data (semi–or unstructured) in centralized, distributed and streaming settings often in the context of other scientific fields (e.g., Cultural Heritage, Environmental Sciences, Educational Sciences, etc.)
