Actividad:
Dr. Escrig obtuvo su grado de doctor en física de la Universidad de Santiago de Chile. Sus estudios de doctorado en el área de nanomagnetismo se enfocaron a la interacción dipolar entre sistemas magnéticos micro y nanométricos. En el Max Planck Institute of Microstructure Physics (Alemania), él estudió los procesos de reversión de la magnetización y las curvas de histéresis de nanohilos y nanotubos magnéticos, desarrollando nuevos métodos teóricos, uno de los cuales es actualmente usado por varios grupos en el mundo. En particular, él es pionero en el estudio de los nanotubos magnéticos, publicando más de 30 artículos en esta área. No solo eso, sino que además escribió un capítulo de libro sobre nanotubos magnéticos en el Handbook de Física. Actualmente el Dr. Escrig lidera el Laboratorio de Nanomagnetismo que cuenta con equipamiento único en el país. Este equipamiento le permite sintetizar y caracterizar nanoestructuras magnéticas con geometrías complejas. Por ejemplo, su laboratorio ha sido capaz de sintetizar por primera ver películas delgadas y nanotubos de NiFe utilizando la técnica de ALD. Su trabajo le ha permitido publicad más de 115 artículos WoS, los que han recibidos más de 2300 citaciones. Actualmente es índice H 26. Además, él ha enviado 5 solicitudes de patente, dos de las cuales le han sido otorgadas. Además de la docencia e investigación, el Dr. Escrig fue un miembro activo de la Global Young Academy, investigador joven de la Academia Chilena de Ciencias, tesorero de la Sociedad Chilena de Física y director del Grupo de Estudio de Física Teórica y Experimental de Fondecyt. Él tiene un amplia experiencia en programas de postgrados y actualmente se desempeña como Decano de la Facultad de Ciencia.
