April 15, 2015: Luís Daniel Abreu is giving a talk in Coimbra next Wednesday, April 22 (16:30, Room 5.5 of the Math. Dept.) titled Harmonic Analysis for the Natural Sciences. It will be a pleasure to listen to his talk. Daniel was our colleague here at the faculty of the Math. Department and teamed up with us in several research grants. Daniel moved to Vienna a couple of years ago. Early this year, he became a Research Associate at the Acoustics Research Institute of the Austrian Academy of Sciences.

April 8, 2015: Youssef Diouanne successfully defended his PhD thesis in October 2014 at the Institut National Polytechnique de Toulouse (École ENSEEIHT). Serge Gratton and I supervised his dissertation, titled Globally Convergent Evolution Strategies with Application to an Earth Imaging Problem in Geophysics. After a short postdoc at CERFACS with Serge, Youssef was offered and accepted an academic tenure track position at the Institut Supérieur de l'Aéronautique et de l'Espace (ISAE) at Toulouse. Il s'agit d'un poste d'enseignant-chercheur en mathématiques appliquées, spécialité optimisation numérique. Congratulations Youssef!

March 19, 2015: In the paper Direct search based on probabilistic descent (see papers), there is a new proof technique for establishing global rates and worst case complexity bounds for randomized algorithms for which the new iterate depends on some object (directions, models) and the quality of the object is favorable with a certain probability. The technique is based on counting the number of iterations for which the quality is favorable and examining the probabilistic behavior of this number.

March 19, 2015: I'm starting a miniature blog here... I hope I'll have something interesting to say once in a while...


Research Summary
My research interests include the development and analysis of numerical methods for large-scale nonlinear programming, sparse optimization, PDE constrained optimization problems, and derivative-free optimization problems, and applications in computational sciences, engineering, and finance.

Biography
I obtained my Ph.D. in Computational and Applied Mathematics from Rice University in 1996. I held visiting positions at the IBM T.J. Watson Research Center and the IMA/University of Minnesota in 2002/2003 and at the Courant Institute of Mathematical Sciences/NYU and CERFACS in 2009/2010. I have been in the faculty of the Department of Mathematics of the University of Coimbra since 1996.
