Difusión y Transferencia


Dissemination and Linkage with the Online Media , Project entitled "Cycle of talks: Biology of cancer and its complexities" in the role of Collaborator. Activities consisted of a series of virtually informative talks on cancer for educational establishments in the Biobío and Ñuble regions, reaching up to 200 students per activity. First Semester 2021

Project "Videos that open doors to a Biochemistry laboratory," in the role of Collaborator. Laboratories and practical educational activities in the COVID19 context sponsored by the project UCO1808 - Educational Innovation and Research Laboratory for learning Basic Sciences. Second semester 2020.

Scientific consultant for EXPLORA projects entitled " Evaluation of the effects of Kalanchoe extracts on cancer cells" 2018-2019

Main dissemination activities of the Pincheira Laboratory involved the participation of researchers and students from the laboratory with schools from the Bio Bio region, promoting basic research and its application in chronic pathologies such as cancer. The research group annually invites students from various regional schools for guided visits to the laboratory.
