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.

Después de licenciarme en ciencias con mención en física  en la Universidad de Chile, inicié mi Magíster en Ciencias Físicas (Universidad de Santiago de Chile) y posterior Doctorado  en Ciencias Físicas en 1995. Mi tesis doctoral fue la Estructura Geodésica del Agujero Negro y Estabilidad Estelar en Tres Dimensiones. Actualmente, mis principales áreas de investigación son la Cosmología Teórica y los agujeros negros de menor dimensionalidad.

Mi quehacer como docente en la Universidad de Santiago se traduce en las asignaturas de Relatividad general; Introducción a la Cosmología; Introducción a la Astrofísica e Introducción a los Agujeros Negros en las carreras de Ingeniería Física, LEFM, Magíster en Filosofía de la Ciencia, Ingeniería Eléctrica e Ingeniería Informática.

Investigación en relatividad general y cosmología, con énfasis en modelos de energía oscura y materia oscura disipativa.

A lo largo de mi vida académica en la Universidad de Santiago de Chile he sido Miembro del consejo académico, Vicedecano de Investigación, Miembro del Comité de Postgrado, Director del programa de Postgrado, Jefe de carrera de Ingeniería Física, Miembro del consejo de facultad y miembro del consejo del departamento.
