Background

Xavier's background is in theoretical chemistry and biochemistry. He uses Quantum, Classical and Statistical Mechanics to build computational models to study the chemical processes of life. At the same time, his passion for computers led him to use molecular simulations and other kinds of visual technology to enhance chemistry learning.

After finishing his PhD in Spain, he went to the United States as a postdoctoral researcher at the University of Wisconsin Madison (www.chem.wisc.edu), to study theoretical models of membrane bound enzymes with computational tools. He went back to Spain to hold a research position at the Barcelona Research Biomedical Park (www.prbb.org). After a year he decided to refocus his interests on education and came back to the US to work in the Chemical Education Digital Library (www.chemeddl.org) and the Journal of Chemical Education, where he developed web materials for learning chemistry.

Teaching

Xavier’s passion for teaching goes beyond his job. He sees chemistry everywhere—in books and people, in ancient history and in daily news, on earth and in space. He sees it all over and tries to get everyone involved in this vision. At UMR, he will be using this passion to design and teach the curriculum for Chemistry and Biochemistry.  In these courses, he wants to not only teach students how to learn, but teach them how to question what they learn, to provoke questions rather than providing the answers.

Research

Research in Molecular Simulations

I create computational models of biomolecules to investigate their chemistry. 

Computers are tremendously useful tools for repeating the same task over and over again. They are used to build atomistic models of biomolecules in their cellular environment. I use a series of tools from Quantum, Classical and Statistical Mechanics to study the chemical reactions involved in the chemistry of life. 

Research on Learning 

I develop web materials to teach science and assess their pedagogical value. On a broader perspective I investigate the role of technology in learning.

The erruption of the Web in educational materials has changed the way technology and information is used in learning. While printed textbooks include pictures, static plots and tables of data, now one can find online digital learning objects with interactive graphics and simulations that add visual and kinesthetic value to the learning experience.

Many areas in science can benefit from graphing tools, interactive applets and simulations.  Knowing the what, when and where of technology in the class is essential for an ever-increasing technical society.
