Acerca de mi


Planetary interiors / high pressure physics

Soy Científico Asistente de Proyectos en el Departamento de Ciencias Planetarias y de la Tierra (Earth and Planetary Science Department) de la University of California, Berkeley, trabajando en el grupo del profesor Burkhard Militzer. Obtuve my doctorado en física de la Universidad de Chile, Chile el año 2015. Estoy interesando en comprender la física de los interiores de planetas solares y extrasolares—en particular, el régimen de altas temperaturas y alta presión— a través del estudio de la materia a nivel atómico, en particular, usando dinámica molecular y cálculos de estructura electrónica basados en la teoría del funcional densidad (DFT). En este marco de trabajo, se pueden obtener ecuaciones de estado de materiales, incluso a presiones y temperaturas donde no hay datos experimentales disponibles, las cuales son fundamentales para construir modelos de la estructura y evolución de los planetas, lo que mejora nuestro entendimiento de los procesos que ocurren en los planetas solares y exoplanetas.
