Bio
After growing up in Mexico City and always having a deep interest in the sea, I moved to a small coastal town on the Gulf of California where I completed a B.Sc in Marine Biology. During this time I studied the utilization of nutrients during the gonadal maturation of an endemic species of octopus, Octopus hubbsorum. Later, I obtained my master's degree in Marine Resources Management, for which I conducted a research on the accumulation of metals in different tissues of the octopus Octopus hubbsorum in a site highly impacted by mining activity. I also carried out a risk assessment for the consumption of this resource. During this time I did a research stay at the University of New Brunswick, Canada, to study the techniques for the determination of metals in organisms. This experience was extremely enriching on a personal and professional level, allowing me to know the bases of research in toxicology and allowing me to win the award for the best national postgraduate thesis (National Polytechnic Institute) 2018. In parallel, I have always been interested in dissemination science, for which I have collaborated as regional manager in The Cephalopod Citizen Science Project, which has research and scientific dissemination objectives. I am currently interested in developing tools to identify the risk of metal contamination in the health of ecosystems in coastal sites impacted by mining activity.
Research project
Proteomic and metabolomic response of octopus Octopus hubbsorum to metal contamination and the risk-benefit analysis of its consumption in a mining-impacted site in the Gulf of California.
