Main research subjects and topics of interest


While in Lille, I worked with Benoît Planquelle, former PhD student at LIFL and now computer scientist at the Rectorat de Lille, Nicolas Baeyens, former graduating student in Applied Math. at USTL and now mathematics teacher, Sébastien Czech, former graduating student in Computer Science at USTL.

I also worked on the parallelization of automatic speech recognition with Yahya Ould Mohamed El Hadj, former PhD student at University Mohamed 1st, Oujda, Morocco, co-directed with E.M. Daoudi, within the framework of the European contract INCO-Keep In Touch Development of Parallel Algorithms for Irregular Problems. He is now Associate Professor at the Al-Imam Muhammad Ibn Saud's University, Riyadh, Kingdom of Saudi Arabia

Work on interval analysis and global optimization has been done with

Francisco José Cháves has worked for his PhD thesis on the implementation and certification of Taylor models using the formal proof assistant PVS (in French). His supervisors were Marc Daumas and myself. This PhD thesis took place in the Mathlogaps framework, a multi-participant Early Stage Research Training Site in MATHematical LOGic and APplicationS (2004 - 2008). Francisco José Cháves now works with Politecnico Grancolombiano, Bogotá, Colombia.

Hong Diep Nguyen has defended his PhD thesis (18 January 2011) entitled Efficient algorithms for verified scientific computing: numerical linear algebra using interval arithmetic under the supervision of Gilles Villard and myself. He is now postdoc at UC Berkeley with Jim Demmel.

David Pfannholzer has worked on a PhD thesis from end 2009 to 2011 under the supervision of Florent de Dinechin and myself.

Philippe Théveny has begun a PhD thesis in 2011 entitled "Numerical quality and high performance in scientific computing on emerging architectures", with problems originating mainly from linear algebra.
