Short CV

Born in Manresa, Catalonia, Spain, in 1964. Graduate in Mathematics, Universitat de Barcelona, 1988. PhD Student and Lecturer in the Universitat Politècnica de Catalunya from 1988 to 1994. Doctor in Mathematics, Universitat Politècnica de Catalunya, 1994. Associate Professor in the Department of Applied Mathematics IV of the Universitat Politècnica de Catalunya from 1997. Senior Research Fellow in the Division of Mathematical Sciences, School of Physical and Mathematical Sciences at the Nanyang Technological University, Singapore from September 2010 to August 2014 (on leave from the position at UPC Barcelona).


Currently, my research is mainly devoted to Cryptology. I belong to the Research Group on Mathematics Applied to Cryptography at UPC Barcelona. I am interested mainly in problems in Algebra and Combinatorics related to Secret Sharing, Secure Multi-party Computation and Information Theoretic Security.

I was a member of the Research Group on Graph Theory and Combinatorics at UPC from 1988 to 2001. I began my research activities in this group as a PhD student. My main interest in this area was the application of Graph Theory to the design of Interconnection Networks.

In the School of Physical and Mathematical Sciences, NTU, I am teaching the graduate course Discrete Methods (MAS-711).

In May-June 2012, I taught a short course entitled Applications of Combinatorics to Information-Theoretic Cryptography at the Central European University, Budapest. The lecture notes for this course are available here.

I have taught many different subjects at UPC:
