I am a Postdoctoral Researcher Fellow at the University of Waikato in Hamilton, New Zealand.
I got Ph.D. from LARCA group, Departament de Llenguatges i Sistemes Informàtics (LSI) at UPC-Barcelona Tech in April 2009. My advisors were Ricard Gavaldà and José Luis Balcázar. | Thesis.
I am interested in Data Streams, Web Mining and Algorithmic foundations of Machine Learning and Data Mining.
Currently, I'm working on MOA Massive On-line Analysis project. MOA is a framework similar to WEKA for data streams, on-line massive data sets.
