In 2012 She obtained her master degree in Materials Science from the Chemistry Faculty in the Autonomous University of the State of Mexico, developing a project aim to the synthesis and characterization of membranes based on natural and synthetic polymers  to  remove  heavy metals from water.  From 2012-2014 She worked on the CFATA-UNAM campus Queretaro on the characterization and research of different materials (nanocarbon structures, nanotribological properties of teeth and nanomulsions for organoleptic purposes). She join the MEMS team in 2014, with a PhD thesis headed in collaboration with the Switchable Molecular Materials team in LCC, Toulouse. The aim of her research is the integration of Spin Crossover (SCO) materials on MEMS devices in order to characterize and explode their actuating properties generated by the reversible volume change which is triggered by different stimuli such as light and temperature. As the nature of this phenomenon occurs at the molecular level, in principle these molecular switches have not limit to conserve their actuating properties while the size of the device is scale down, giving place to a new generation of materials for MEMS-NEMS purposes.
