Maestra en Ingeniería Ambiental y Tecnologías Sustentables , actualmente se encuentra en el 6º semestre del doctorado en ingeniería Ambiental (especialidad en agua) de la UNAM en la sede del Instituto Mexicano de Tecnologia del Agua, su investigación se basa en la electrooxidación como tratamiento de aguas residuales para la eliminación de contaminantes emergentes.
Previo a iniciar el doctorado, fue coordinadora del comité de certificación de la empresa EQA México durante 2 años (2018-2019), en donde era responsable de la coordinación de los comités para la revisión de la información para obtener la certificación de los Sistemas de Gestión ISO para empresas de distintos sectores.
Desde 2016 brinda consultoría ambiental como especialista externo para empresas como Biota y e3 consultoría ambiental, en donde ha desarrollado proyectos como, la evaluación de la calidad de agua y nutrientes de la laguna de Términos en Campeche, Planes de manejo de residuos sólidos urbanos y residuos peligrosos para Aeropuertos (Campeche y Oaxaca) y Gestión en materia de agua para una minera (Oaxaca).


The amount of electrogenerated oxidants from NaCl and Na 2 SO 4 used as support electrolytes was quantified to compare their production in one electrochemical oxidation
reactor divided by anion exchange membrane and in another undivided reactor, as well as to evaluate the effects of various operational parameters. The introduction of an anion exchange membrane and the injection of O 2 in the cathodic zone is expected to increase the amount of oxidants, compared with their production in an undivided reactor. It was found that the addition of O 2 in the cathodic zone of the divided reactor has the main influence on the oxidant generation when Na 2 SO 4 is used as electrolyte, generating up to 32.98 µM. The increase of peroxydisulfate in the anodic zone of the same reactor is mainly influenced by the electric current, generating up to 198.65 µM. The current is
also the main factor for the generated oxidants in the undivided reactor, generating 57.61 µM. When NaCl was used as electrolyte, the generation of active chlorine is
mainly influenced by the electric current in both zones of the divided reactor, generating in the cathode zone up to 51.01 µM of ClO - , and 1427.28 µM of Cl 2 in the anodic zone,
while 982.14 µM of ClO - were determined in the undivided reactor. The introduction of the anionic exchange membrane produces higher quantities of electrogenerated oxidants, compared with the generated in the undivided reactor, especially in the anodic
zone.
