Juan Pablo Benitez: Master in medical and biological sciences. 2015.
Helen Hernandez: Engineer in Biotechnology. 2015
Camila Donoso: Master in Nutrition and Food minor in Human Nutrition. Ready to finish by 2017
Ailynne Sepúlveda, Miltha Hidalgo and Vania Rodríguez, completed their thesis in the program of Master in Nutrition and Food minor in Human Nutrition. 2019
Yarella Pizarro completed her thesis in the program of Master in Nutrition and Food minor in Human Nutrition. 2022
Christine Kriendl has a PhD in Nutrition and Food from the University of Chile. 2024
Christian Sagredo, Daniela Rivas, Kurt Pohlhammer, Jorge Meza, Benjamin Armijo, Francisca Chávez, Guillermo Lagos, Jaime Acevedo, José Coronado and Mará Paz Hernández have been trained at my lab in techniques such as cellular culture and imaging recording in living cells. This academic activity is a pre-requirement to obtain their final degree in Biotechnology Engineering.
Since 2015, I have been in charge of outreach of the scientific meeting "ION IN THE VALLEY", which takes place in Paihuano, IV región, Chile. Our activivities have consisted in talks to students from local and public school from the zone. Currently, We are moving to integrate our initiatives with the comunity towards the creation of pedagogic enviroment designed to enrich the understanding of its local reality.
2018-2019 We have extended our collaborative connections with the Instituto Forestal located at Coyhaique, an extreme southern region of Chile and also with the Tarápaca University at the northern extrem of our country. We expect to shape a network for research the patrimonial/ancestral foods from patagonia to altiplanic environments and give scientific supported nutritional value to the communities that keep these living cultural items.
