Research & Professional Achievements
My research focuses on emotional memory, fear learning, and directed forgetting. I have received competitive postdoctoral fellowships from the Research Foundation Flanders (FWO) and have been recognized with multiple awards, including a commendation from the Society for the Improvement of Psychological Science (SIPS). In addition to my research, I serve as Associate Editorial Board Member at Behaviour Research and Therapy and act as an ad hoc reviewer for several high-impact journals in cognitive, biological, and clinical psychology.
