Research and Profession

Current Research Activities

Interdisciplinary

I obtained the "L’oreal National Prize- UNESCO-CONCYTEC for Women in Science 2017" sponsored by CONCYTEC, Science National Academy (ANC) and L’oreal in Perú. Currently, I am part of the National Pro-Women in Science, with the aim of proposing mechanisms that make women's work in science visible. The current research foci on the evaluation of the presence of marine litter in fishery resources.

Current profession

Current professional activities type: 
Research
The current research foci on the evaluation of the presence of marine litter in fishery resources along the coast of Peru and Lake Titicaca, where volunteering of “scientific citizens” will be promoted to raise awareness of Peruvian society with the problem of plastic pollution in the sea.
