Hello, my name is Mario José do Canto Filho and I am a doctor formed by the Federal University of Santa Maria in Brazil for more than 20 years and work as a family doctor in public attention. Now I am doing a Master's in Public Health at University College Dublin. I really enjoy teaching, especially the basic and clinical subjects, such as cytology, histology, biochemistry, physiology (is my favorite), pharmacology and all basic clinics. I think fascinating the functioning of the human body, from the small cell to the neuro-hormonal control of the whole body. I help you understand that too.
