      Tras obtener el t\u00edtulo de licenciado en Ingenier\u00eda Qu\u00edmica por la universidad de Cuenca en Ecuador, expand\u00ed mi perfil acad\u00e9mico al conseguir el grado de m\u00e1ster en Ingenier\u00eda Qu\u00edmica en la Universidad de Zaragoza. M\u00e1s tarde, continu\u00e9 especializ\u00e1ndome en ingenier\u00eda de procesos lo que me permiti\u00f3 obtener mi t\u00edtulo de doctor, en la misma instituci\u00f3n mediante la investigaci\u00f3n en procesos redox para la producci\u00f3n de hidr\u00f3geno a partir de gas natural.<\/p>\n

      A partir de entonces, formo parte del grupo de Cat\u00e1lisis e Ingenier\u00eda de Reactores CREG como investigador postdoctoral, donde compagino adem\u00e1s labores t\u00e9cnicas dentro del Laboratorio de Tecnolog\u00edas del Hidr\u00f3geno. Actualmente, mis investigaciones experimentales se enfocan en el dise\u00f1o de reactores catal\u00edticos, procesos termoqu\u00edmicos relacionados con el uso de hidr\u00f3geno y biocombustibles y utilizaci\u00f3n de membranas catal\u00edticas permeoselectivas.<\/p>\n
