During the last 10 years I have participated in the dissemination of the research that we carry out in the production of biopharmaceuticals. Firstly, nationally through the CONICYT Explora program, through the participation of the activity 1000 scientists 1000 classrooms, framed in the CONICYT science and technology week. I have made this diffusion for students of basic and secondary education, in private subsidized and municipal schools.
Second, at the international level through the participation of different congresses and seminars in the field of Biotechnology, such as the European Biotechnology congress, and specifically in the area of in vitro culture technology for mammalian cells, such as the "European Society of Animal Cell Technology (ESACT) Meeting "and the" Latin American Symposium on Cell Culture Technology (SLATCC) ".
