Data Management, Exploration and Mining (DMX) - Visitors 2011

Visiting Researchers


Guillem Rull Fort

I got my PhD on January 2011 in the Department of Software at the Technical University of Catalonia (UPC), in Barcelona, Spain. My thesis was about the application of query containment techniques to the validation of schema mappings, and was sponsored by Microsoft Research under the MSR European PhD Scholarship program. My supervisor was Dr. Ernest Teniente. My research interests so far have been focused on reasoning on database/conceptual schemas and mappings. Besides research, I enjoy a good book, watching movies, and I also like to play videogames.





Bolin Ding

I’m a PhD student in the Department of Computer Science at UIUC. My advisor is Prof. Jiawei Han. I’m interested in efficient algorithms and index structures for datamining and databases in general. Besides efficiency, I also care about people’s privacy. Before joining UIUC, I got my MPhil degree on System Engineering in the Chinese University of Hong Kong under the supervision of Prof. Jeffrey Xu Yu, and my BS degree on Math and Applied Mathematics in Renmin University of China. I play Go, Pingpong (table tennis), and basketball. My homepage:


Daniel Fabbri

I am a fifth year Ph.D. student at the University of Michigan, working with Kristen LeFevre. My research interests are database systems and database security. My current research is focused on analyzing access patterns in electronic health record systems and explaining why these accesses occur.
