SYPMAT: a multidisciplinary research group (SYnthesis and Processing of MATerials)

The Universidad Carlos III de Madrid is one of the six Public Universities that there are in Madrid. It is a really young University, it was created in 1988.
There are three campuses (Getafe and Leganés in the south of Madrid, about 15 km from downtown) and Colmenarejo in the West part of Madrid and far away from the city about 45 km).
In Leganés, where we are, is located the Engineering School.
Here some pictures of Leganes Campus. And here appear some figures of our University:
