Diego Cortez Quezada

Systems Biology and Synthetic Biology Laboratory Researcher

Associate Professor

Academic history

Diego Cortez was born in México City where he studied Biology and a Master degree in Experimental Biology at UNAM. His PhD was at the Pasteur Institute in Paris and the Postdoc at the University of Lausanne, Switzerland, working on functional genomics of mammalian sex chromosomes (Cortez et al Nature 2014).

Diego started working at the Genomic Sciences Center of UNAM in 2015, and since 2016, his projects are funded by CONACyT-SEP Basic Science, UNAM-PAPIIT, CONACyT-Frontiers in Science and the Royal Society-Newton Foundation.

Diego works in the lab and in the field seeking to understand the causes of transitions between sex determination systems (from temperature to genetic sex determination). Currently the main project of the laboratory aims to understand the degeneration of the sex chromosomes and the short life expectancy of males in 8 families of reptiles native to Mexico.

The laboratory has several open positions at all levels. Interested students please send an email to dcortez@ccg.unam.mx
