In all these courses, I have told students about connexins, hemichannels, cleft junctions, and lab results.

In 2018, I participated in the science week of the Alianza Francesa school, Chamisero headquarters. On that occasion, during one morning I talked to kindergarteners about science and also did a series of basic experiments on chemistry and physics.
Also during 2018, I gave several interviews to electronic newspapers and radio and TV programs, about the role of Cx46 in diseases such as cancer.

- Also during 2018 and 2019 I participated in the Biology Study group 2 in ANID.

Finally, during the months of July and October 2019, with a group of 5 girls from Boston College La Farfana School in the Maipú commune, we did experiments in my laboratory on the effect of Chilote garlic and different types of paprika on the death of cancer cells in mom. They learned from cell culture to doing cell death experiments on a Nikon microscope. They found that a chilote garlic extract induces cell death even when the extract was highly diluted.
