During the academic years 86-88, I was working in Optimization in the Mathematical Science Department of Rice University under the direction of Professor John E. Dennis. After that through

a NSF grant I have spent time in differet summers in that Department working in areas of common interest with Professors John Dennis and Richard Tapia.

My work in Optimization started around the problem of minimizing a quadratic convex function over the set of symmetric positive semidefinite matrices with rank less than or equal to k. This is an optimization problem related to the problem of finding the nearest distance matrix with fix embeding rank to a given predistance matrix.

A first approach was to transform the problem into an unconstrained problem, this allows us to use standard software to obtain local minimizers, but this is clearly not enough. More research about

the structure of the problem and specially the constraint sets is needed. Also more numerical experimentation has to be done in this area.

Working on the cone of symmetric positive semidefinite matrices, an interesting property came up, and allowed me to get interesting bounds for eigenvalues of symmetric matrices as well as related these bounds to the geometry of the cone. Lately we also obtained estimates for singular values

using similar techniques.

Because the important relation between the optimization problems and the structure of the cones of positive semidefinite matrices and the distance matrices we have been lately studying their

structure. All this area is strongly connected with applications, in particular with the multidimensional scaling problem in statistics and the molecule conformation problem using the

approach of distance geometry. This molecule conformation problem is a high priority in molecular biology, moreover structural biology and pharmaceutical design have been listed as two of

the "Grand Challenges" in high performance computing by the U.S. Research and Development Program.

An important related area is completion problems, I am interested in this area too and some results have been obtained. On the other hand distance matrices completion are under study at the present.

In the future, I would like to continue in this area as well as study more about the algorithms for the optimization problems. I am interested too in any related problem. Most of results obtained in these areas are in the papers:
