Arqueología Galáctica / poblaciones estelares, estructura, cinemática, composición química, formación y evolución de la Vía Láctea / Parámetros fundamentales estelares y abundancias químicas; espectroscopía estelar

Actividad:

Mi investigación se enmarca en el área de la llamada Arqueología galáctica, y se orienta al estudio de las poblaciones estelares de la Vía Láctea, especialmente aquellas ubicadas en la parte central de esta, el llamado bulbo galáctico. He utilizado datos de mapeos fotométricos (VVV survey), astrométricos (VVV y Gaia), y especialmente, espectroscópicos (Gaia-ESO survey, APOGEE survey) para entender la composición química de las estrellas del bulbo y relacionarlas con su distribución espacial y cinemática. Esto es parte de un esfuerzo de largo aliento cuyo objetivo final es el comprender la historia de formación y evolución de nuestra galaxia.

Soy uno de los investigadores principales del Núcleo Milenio Evolución Reconstruida del Medio Interestelar (ERIS), iniciativa en la que nos hemos propuesto unir fuerzas con biólogos y matemáticos para aplicar unos de los principios de la teoría de la evolución de Darwin -descendencia con modificación- para entender la evolución cósmica a partir de información de la química de las estrellas.

Disfruto enseñando y conversando de ciencia, y en este sentido, intento transmitir la belleza encerrada en la naturaleza de las cosas, tanto en mis clases como en las actividades de divulgación; es una responsabilidad, y también un privilegio, el poder compartir con la sociedad los frutos de la investigación y el descubrir científico.

Actividad:

Desarrollo estratégico de ciencias espaciales en el Departamento de Física de la Universidad de Santiago de Chile.

El proyecto a desarrollar en la Universidad corresponde a una mezcla de investigación en Física de plasmas espaciales y de desarrollo de modelos predictivos de Clima espacial. De esta forma, mi inserción en el departamento de Física abre una línea de investigación en magnetósfera terrestre interna, principalmente dinámica de los anillos de radiación, e interacciones entre el viento solar y la magnetósfera terrestre. Adicionalmente, el proyecto contempla una línea más aplicada de modelamiento y predicción de clima espacial usando ciencia de datos con objetivos tanto predictivos como de evaluación de riesgo.

Otro de mis objetivos es explorar los procesos de pérdida de electrones relativistas en los anillos de radiación de Van Allen, a la vez que identificar las condiciones geomagnéticas así como los procesos físicos favorables para dichas pérdidas. Estos estudios serán complementados con el desarrollo de modelos empíricos de flujos de electrones relativistas usando ciencia de datos, utilizando para esto la gran disponibilidad de datos actualmente existentes.

Finalmente, el proyecto contempla el desarrollo de un sistema de monitoreo del campo magnético terrestre para complementar la red de magnetómetros SAMBA actualmente existente en el país, con el fin de evaluar la factibilidad técnica de utilizar instrumentos pequeños y de bajo costo para realizar estudios científicos de gran escala.

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.

Actividad:

Después de licenciarme en ciencias en la Facultad de Ciencias Físicas de la Universidad de Chile el año 1993, inicié mi Doctorado en Ciencias Mención Física bajo la tutela del profesor Enrique Tirapegui. Mi tesis de grado fue sobre fenómenos en fluidos viscosos y parte del área que se conoce con el nombre de Física No Lineal. Titulado en el año 1996 mi próximo paso fue realizar un postdoctorado en el Massachusetts Institute of Technology (MIT) bajo la guía del profesor L. Mahadevan.

Mi trabajo en la Universidad de Santiago se inicia en 1998 en la cual ha sido mi filiación hasta ahora. En el año 2001 tomé una posición de profesor visitante en la Universidad de Cambridge hasta el año 2003 en el Deparment of Applied Mathematics and Theoretical Physics (DAMTP, Cambridge-Inglaterra) y luego retomé mi labor académica en la Universidad de Santiago. Desde esa fecha hasta ahora he realizado una labor continua de labor académica e investigación.
