Education

Fall 2003 - April 2008: Ph.D. in Chemistry, Iowa State University, USA, with Prof. Victor Lin.

1988 - 1995: License Degree in Chemistry from San Carlos University in Guatemala.

Current Research

My work is focused on the functionalization and structural design of mesoporous silica nanoparticles (MSN) for studying their interactions with live cells.  Besides of trying to improve the abilities of MSN as a drug/biomolecule delivery system, we are trying to understand the way MSN are taken up by cells, and their intracellular processing.  The latter might allow us not only to achieve a new way of controlling cell metabolism but also to provide a new tool to use in the quest to understand some more the wonderful chemistry that occurs within life.
