This very personal way to do Mathematics is
Applied Mathematics, but often dealing with problems using tools from
Convex Analysis & Geometry,
Algebra & Combinatorial Geometry,
Optimization, Operations Research, and Data Science,
Other application areas.
I run a weekly seminar for my research group. Because of my interests, it was
baptized as the CCACAOO Seminar
(indeed, it provides sweet intelectual caffeine and speakers bring chocolate to share too). Contact me if you are interested to attend.
Here is a summary of my past work , with some highlights.
Most of my papers since 2002 are available at the mathematics ArXiv.
I am glad to send old reprints by request.
