Teaching

Before that, I also taught Introducción a la Mecánica Cuántica Relativista (Introduction to Relativistic Quantum Mechanics) for graduate students, Tópicos Especiales (Special Topics) and Tópicos Selectos de la Mecánica Cuántica (Selected Topics of Quantum Mechanics) for graduate students (The latter were two tutorial courses involving only one student), Mecánica Cuántica I (Quantum Mechanics I) for graduate students Mecánica Clásica (Classical Mechanics), Métodos Matemáticos de la Física II (Mathematical Methods of Physics II) in undergraduate level, Electricidad y Magnetismo (Electricity and Magnetism), Física General I (General Physics I), Física Cuántica I (Quantum Physics I), Aplicaciones a la Física, para matemáticos (Applications to Physics, for mathematicians) and Mecánica (Mechanics). Also in the past I've taught Física General III (General Physics III), and Física General II (General Physics II).

About me

- I enjoy so much to teach physics, specially quantum mechanics (I like to extract continually new results from model problems), and also mathematics (differential operators, distributions, etc). I speak Italian, Spanish and English. I am a very enthusiastic, libertarian and idealistic person. I like soccer (Juventus  is my favorite team) and the music of Italy. I love traveling, making pizzas, going to the beach and watching news on TV, these are my hobbies. I am always eager to know new people also working in physics.
