Currently I am co-supervisor of a doctoral student at the Institute of Astrophysics at the Pontificia Universidad Católica de Chile. The project consist on developing orbital models for stellar streams and satellite galaxies of the barred galaxy Malin 1 which is a Giant Low Surface Brightness galaxy (GLSB), to understand the evolution of the environment of GLSB galaxies.
I also supervised an undergraduate student for a summer project at the Astronomy Department at the Universidad de Chile. The project consisted on modelling the orbits of star clusters located in the stellar halo of the Milky Way and explore tidal interactions.
