I'm a research engineer at CMM - a departement of Mines-ParisTech doing research in the domain of Mathematical Morphology.

Everything may interests me but, surely, I can't be an expert in every domain. Meanwhile, I'd like to, at least, understand the basics of each domain.

Some domains I'm curious and I try to follow in the last years are machine learning (very) and its applications (image processing, network security, text classification and data mining, …), statistics, performance evaluation, …

On the 'pratical' personal side, I practice photography. Mostly in black and write and, whenever possible, with old film gears (rolleiflex, hasselblad, leica, …). Take a look at my web site.

On the 'theorical' personal side, I'm interested mostly in anthropology, philosophy, arts in general (history, philosophy, practices, …)… Remember I said : I'm curious !!! Photography is just a way to practice anthropology.

I'm the author of a open source software intended to filter messages (spam, …) at mail servers : ze-filter, previously named j-chkmail. Take a look at it …

EMEA Winner: Jose Marcio Martins da Cruz, Ecole des Mines de Paris for his contributions to libmilter (the library that implements the Milter protocol and provides the API to applications). This contribution delivered an alternative implementation of the threading model, providing improved performance for operating systems such as Linux.
