My interest extends to clinical Psychology and in particular research on the treatment of trauma and stressor-related disorders in children, adolescents, and adults. 

As a lecturer, I am affiliated with Psy-zo! Education, where I offer education in the areas of CBT and EMDR therapy.

In this PhD track, I will conduct collaborative research into the
