Difusión y Transferencia


Reviewer for projects in the framework of the school science fair in Valdivia (Chile)
Once upon a time... Project founded by the German Federal Ministry of Education and Research. The project’s aim is to communicate science by creating short stories. The audience for these stories is adults with connection to children from different countries. https://www.marum.de/Binaries/Binary15164/Once-upon-a-time-OUAT2017.pdf
(Radio Interview) "Junge Forscher der marinen Mikrobiologie in Bremen" Happy Hour Radiostation Bremen 4\\
(Radio Interview) "Materia expuesta" Radiostation UACh\\
Appearance in the (TV Documentary) Cazadores de Ciencia (Science hunters). TV show on the Chilean National TV about science where one week fieldwork in Mocha Island was filmed and presented in the format of documentary (see Jessen et al., 2011 for details regarding the scientific findings) http://oceanografia.udec.cl/news/english/research-at-isla-mocha
(Lectures for elementary schools) in the framework of 1000 Científicos, 1000 aulas (1000 scientists, 1000 classrooms). A series of scientific lectures were given to scholars from different ages with the aim of promoting understanding of science in kids and teachers http://1000cientificos.explora.cl (in Spanish)
