Presentación
Obtuve mi título profesional de Ingeniero Físico en la Universidad de Santiago el 2003, junto al grado académico de Licenciado en Física Aplicada. Posteriormente cursé mis estudios de Doctorado en Física en el Kungliga Tekniska Högskolan (KTH, Royal Institute of Technology) en Estocolmo, Suecia entre 2005 y 2009, defendiendo mi tesis doctoral en el estudio del mecanismo atomístico de fusión de los sólidos en condiciones extremas de presión y temperatura, tesis que fue supervisada por el Prof. Anatoly B. Belonoshko.
A mi regreso a Chile realicé un postdoctorado financiado por FONDECYT en el departamento de Física, Facultad de Ciencias, Universidad de Chile y posteriormente ejercí como profesor instructor en el mismo departamento hasta octubre 2015, cuando ingresé a la Comisión Chilena de Energía Nuclear, en el entonces Departamento de Plasma Termonuclear (DPTN) y ahora Centro CCHEN de Investigación en la Intersección entre Física de Plasmas, Materia y Complejidad (P\(^{2}\)mc). En 2017 fui jerarquizado como Profesor Asociado Adjunto de la Universidad Andrés Bello, como parte del convenio de colaboración entre CCHEN y UNAB, y formé parte del comité del programa de doctorado en Física de dicha universidad hasta 2022.
A la fecha he publicado 114 artículos científicos, 88 de ellos indexados en Web of Science. Mi índice \(h\) (Web of Science) es 16, he dirigido cuatro tesis de postgrado y tres de pregrado en Física, y he participado en proyectos FONDECYT Regular y Anillo CONICYT (actualmente ANID) como investigador principal y coinvestigador. Mis líneas de investigación incluyen Mecánica Estadística Computacional, Física Estadística fuera del equilibrio, Inferencia Bayesiana y Teoría de Información, Física de Materiales Computacional.
