LÍNEA DE INVESTIGACIÓN

Sus líneas de investigación se basan en el estudio de mecanismos fisiológicos, bioquímicos y moleculares asociados a los mecanismos de tolerancia, promoción del crecimiento vegetal y resiliencia a condiciones de Cambio Climático, que intervienen en la interacción Suelo-Planta-Microorganismos en suelos contaminados por xenobióticos (metales pesados, metaloides, hidrocarburos policíclicos aromáticos y plaguicidas).  Entre los microorganismos estudiados destacan Bacterias (Plant growth-promoting de vida libre y endófitas) y Hongos rizosféricos tales como: micorrizas arbusculares, endófitos, septados oscuros y degradadores de materia orgánica.
