Professional Interest

I've been working with synchrotron radiation since 1996. I started as a general user of the LNLS, the Brazilian synchrotron facility at Campinas. In 1999, I joined the LNLS as a posdoc at the X-ray Spectroscopy Group. After my 2-year stay in Campinas, I returned to Argentina for a short period of time. In 2002,  I joined BioCAT and I've been working here since then.
My research interest is split between biological applications of x-rays: microfluorescence and microXAFS in biological samples and atomic physics. .

 Personal interest

I devote my spare time (not a lot I should say) to find my family roots and to reconstruct my family tree.  My ancestors came from the region of Molise, Campobasso, Italy. Although there is a small village named Villeta Barrea in Italy there are no Barrea's living there. I found hundreds of Barrea's in a small town called Tufara. I have not been able to research nearby towns to find more relatives yet. I expect to find even more Barreas in those towns.
I 'm preparing my current results and they will be posted soon. The information is published in English, Portuguese and Spanish.
If you are interested in this kind of research you'll find very useful information at http://www.familysearch.org . This is the best family history resource site you'll find in the internet. If you have any question about how to use the information that can be access there, you can email me at   rbarrea@gmail.com. I'll be glad to assist you in your search.

Interés Personal
Dedico parte de mi tiempo libre, no mucho por supuesto, a buscar mis raices familiares e incorporarlas en mi arbol familiar. Mis resultados hasta la fecha indican la presencia de una alta concentración de miembros de la familia Barrea en la region de Campobasso en Italia, especialmente en un pequeño poblado llamado Tufara. Mi busqueda ha estado de alguna manera limitada al poblado de Tufara pero espero encontrar mas miembros de la familia Barrea en pueblos vecinos inclusive en otros regiones de Italia. Estoy trabajando en la presentación de mis resultados para publicarlos aqui oportunamente. La información se encuentra en Español (Castellano) e Ingles. La versión en Portugues está todavia en construcción. Pronto será publicado en este sitio. La familia Barrea es originaria de Italia de la región de Campobasso, Molise. En mi busqueda genealogica he encontrado en el pueblo de Tufara una alta concentración de Barreas en los años 1810 hasta 1910. Los años anteriores y posteriores están aun en estudio. Estoy trabajando arduamente para completar el cuadro familiar entre los años 1810 y 1910.
Mi sitio de historia familiar preferido es http://www.familysearch.org . El sitio de busqueda de historia familiar  por excelencia. Si tienes dudas de como acceder a la información que alli se encuentra me puedes escribir a  rbarrea@gmail.com. Con mucho gusto te voy a ayudar en tu busqueda.
