I am an associate professor in the Physical Chemistry
department  of the University Complutense of Madrid, Spain.

I use computer simulations to understand the phase behaviour of condensed-matter systems. Let me explain what do I mean by “condensed-matter”, “phase behaviour”, and “computer simulations”.

A condensed-matter system is a set of particles (molecules/colloids) that “live” together in any non-gaseous state; namely  crystals (e. g. ice, rock salt), fluids (e. g. water, milk), liquid-crystals (e. g. liquid found inside displays), gels (e. g. tooth paste, ice cream), glasses (e. g. window glass, optical fibre) and solutions (e. g. saline solutions, liquid mixtures). Condensed-matter systems have many potential applications, hence being of great interest understanding their properties from a fundamental point of view. 

Understanding the phase behavior of condensed matter systems implies knowing at which conditions (temperature/pressure/external field) the aforementioned aggregation  states (solids, fluids, liquid-crystals, gels, glasses, solutions) are stable, and understanding how they transform into each other. This is a crucial issue because the macroscopic properties of the system dramatically change from one aggregation state to another. 

The behavior of a condensed-matter system can be emulated in a computer simulation  where the system's constituents --atoms, molecules, colloids...-- are moved according to the interaction forces between them. As a result of a computer simulation one can establish a link between the microscopic and the macroscopic behavior of the system, a valuable information that can not be easily obtained experimentally.
