He dirigido tres tesis de pre grado en la universidad autónoma de Chile:
- Prevalencia de Síndrome de Apneas del Sueño en pacientes con Enfermedad Pulmonar Obstructiva Crónica pertenecientes al CESFAM Arturo Baeza Goñi de San Joaquín.
- Comparación de valores de inflado de balón traqueal en un modelo artificial entre un manómetro artesanal y un manómetro comercial.
- Entrenamiento Muscular Respiratorio con válvula umbral regulable en pacientes con lesión medular: Una revisión sistemática.

Actualmente dirigo dos:
