Biografía

I am currently Associate Professor in the Department of Physics of the University of Santiago de Chile (USACH) and led the Nanomagnetism Research Group (www.nanomagnetismo.cl). My group is composed, in addition to myself, for 2 postdocs, 5 PhD students and 2 undergraduates. My research focuses on magnetic systems, although the last time I started working in energy. One of my main research subjects is the study of processes of magnetization reversal and hysteresis curves of magnetic nanowires and nanotubes, developing several new methods to calculate the magnetic coercivity as a function of the angle at which the external field is applied. This method has been considered as an alternative to the method of Stoner-Wohlfarth. Today, different groups around the world are using it in Spain, Brazil, Germany, Slovenia, Argentina, Colombia, and USA. What makes our research unique with regard to another that may exist in the world is the variety of techniques with which we face the problem. In fact, I have the first atomic layer deposition (ALD) in Chile. This allows us to synthesize magnetic nanotubes, which was the main difficulty we had in Chile. I am a person who believes that the role of science is to create a better world for us all. Thus, I have always been associated with various initiatives to achieve this goal, for example, as a young researcher of the Global Young Academy and the Chilean Academy of Sciences. I am coordinator of the Pronano Initiative (www.pronano.cl) that organizes a workshop and an online course for school teachers, as well as a competition for students. Also, I have given several talks at schools and the general public, most of which related to nanoscience, superconductivity, and global warming.
