En la formación de recursos humanos a nivel de posgrado, fue la profesora guía de un doctorando que finalizó con éxito su proceso de formación desarrollando técnicas de control robusto y estimación para sistemas descriptores variantes en el tiempo. Además, supervisé 6 tesis de magíster y fue coguía de tres tesis de magíster y de doctorado vinculadas al área de inercia sintética. De 2019 a 2023, fue el profesor patrocinante de 3 postdoctorandos-ANID.

En pregrado, desde 2013, supervisé el trabajo de titulación de más de 14 ingeniero(a)s, que trabajaron con la utilización de técnicas de control robusto, como control H_infinito, en diferentes aplicaciones, como por ejemplo sistemas de energía, robótica o UAV.
Se salienta que parte de los trabajos de memorias de pregrado desarrollados resultaron en publicaciones de conferencia del tipo SCOPUS, y que gran parte de los titulados quedaron interesados en seguir en estudios de postgrado.

Los resultados resultante de las investigación son en general publicados en revistas indexadas y presentados congresos IEEE o IFAC.

De 2015 a 2018, participe del Programa Explora Conicyt 1000 Cientificos 1000 Aulas, dictando charlas sobre control automático para estudiantes de la enseñanza media.
