I lead R&D teams that work on Big Data + Semantic Computing. (Semantics for us means primarily very large knowledge representation, but we also encompass learning and data mining as useful)
As a scientist, I have a broad multidisciplinar scientific knowledge but also strong focus on anything that is related with Semantics on the Web ( my main project has been http://sindice.com ) and now focusing on enterprise use cases ( http://sindicetech.com ).
