Difusión y Transferencia


Apart from regular appearance in mass media, it would be interesting to highlight two events:

1. Interview of the Explora Program Igualmente Sabias: "Científicas sin Fronteras" (Equally Wise: "Scientists without Borders"): https://www.youtube.com/watch?v=GvfUgaveook

2. A short amateur movie "Burya" presented in “Festival Participativo de Arte, Ciencia y Educación” (“Participatory Festival of Art, Science and Education”). I proposed the original idea, and participated in the scriptwriting. Also I acted as cameo alongside Russian Cosmonaut Alexander Balandine, Dr. Marcos Díaz (Deputy Director of the current project) and other scientists from varios institutions and countries. Directed by renowned Chilean filmmaker Fernando Lavanderos, the movie promotes the importance of space science and international collaboration: https://www.youtube.com/watch?v=8rSbMgLE_X0

3. A citizen science initiative, organized by researchers from Physics Department/USACH (https://www.hagociencia.cl/). I proposed the idea to use the cell phones to estimate the alteration of the total electron content in the ionosphere during the total eclipse. The results of this initiative were presented at the 3rd Shaw?IAU Workshop on Astronomy for Education (2021).

4. I was one of the protagonists of the book "Antártica: relatos de exploradoras en el corazón del planeta" (Antarctica: stories of female explorers in the heart of the planet) written by N. Politis (https://mujeresconciencia.com/2021/11/11/antartica-relatos-de-exploradoras-en-el-corazon-del-planeta/)
