Quillien is currently involved in a research project aiming at improving people with disabilities’ quality of life in the Republic Democratic of Congo. The focus will be to evaluate the impact of a series of interventions and trainings in the Kisangani region. Did those interventions enhance common folks' awareness about the condition of those who live with disabilities?
On the research front, Quillien is also involved with four active research aiming at applying the “Z” model of cognition. Research topics such as linguistic relativity, environmental organization, emotional intelligence, and complex problem-solving are under scrutiny.
Quillien is currently developing new research around the construct of resilience.
