I have directed one PhD thesis and four Master's thesis in Physics at Universidad de Chile (presently guiding another PhD student).
At FCFM, U. de Chile I have taught 105 different courses of the first years of Engineering, of the Bachelor's
program in Physics and of the Graduate program in Physics. Also I have guided 6 undergraduate students in introductory courses to research in Physics.

I have done of the order of 10 presentations to school audiences, introducing Magnetism to them.
