CARLOS A. ZULUAGA Biographical Sketch Research and Teaching Interest The main focus of my research in the last years has been the application of thermodynamic models to unravel metamorphic and tectonic histories of high-grade metamorphic rocks. I´m interested in the physical and chemical properties of minerals and relations of these properties with mineral stability under various system conditions (e.g., pressure, temperature, and system composition). I use a methodology that involves computer models to construct phase diagrams for metamorphic rocks. These diagrams are important in the construction and interpretation of pressure-temperature-time paths that in turn can give clues about tectonic models for orogens. I am also interested in applying thermodynamic models to understand partial melting in the crust during orogenic processes. Understanding partial melting is crucial for interpretations of the roles that deformation, melt generation and pluton emplacement play in the evolution of the crust. Regionally, I am interested in understanding the tectonic evolution of the Colombian Caribbean Margin. My research in the Caribbean margin in the last years has focused on regional and detailed mapping and characterization of metamorphic rocks. I am particularly interested in a tectonicmetamorphic belt interpreted as Cretaceous in age, because this belt may record the evolution of the boundary since the insertion of the Caribbean plate between North and South America. The courses I teach are related to my expertise and to my research interests. The goal is to have students prepared in the broad topic of hard-rock geology so they can get involved in research projects during their studies (bachelor or master programs). The list of classes I have taught include: mineralogy, petrology (igneous and metamorphic), geochemistry, thermodynamics, and isotope geology. In my career as a professor I have had the opportunity to teach these topics at the graduate and undergraduate level in undergraduate – graduate institutions and liberal arts colleges (Pomona College and the University of Minnesota at Morris).
