Currículum Vitae

Soy Doctor en Químicas por la Universidad de Zaragoza desde 1999, y vengo desarrollando mis trabajos de investigación en cromatografía y Química del Aroma desde 1993 como estudiante, investigador contratado, y en estos momentos profesor ayudante doctor en el Departamento de Química Analítica de la Universidad de Zaragoza.

 

Durante estos 10 años, mi experiencia investigadora se ha centrado en la Cromatografía y en su aplicación a la Química del Aroma. Dentro del Laboratorio de Análisis del Aroma y Enología grupo de investigación al que pertenezco y con el que he publicado una veintena de artículos en revistas internacionales.

Es posible acceder a mi currículum completo en inglés en formato pdf aquí.

 

Las líneas de investigación de nuestro grupo se centran fundamentalmente en el aroma del vino de donde obtenemos la mayor parte de nuestros fondos, aunque también hemos trabajado con otras productos como cerveza, te, licores y aceites esenciales, entre otros.

 

Algunas direcciones interesantes relacionadas con la Química del Aroma son las siguientes:

Base de datos Flavornet de Terry Acree.

Leffingwell & Associates: buena colección de links.

Chemical Separations: excelente recurso docente para comprender las técnicas cromatográficas.

Grupo de Cromatografía del  Profesor Luigi Mondello: Pioneros en Cromatografía Multidimensional en Europa.

Wine Flavour Research: recursos varios para comprender el aroma en general y el vino en particular, por Jan Petka.
