About me

I joined BAND-lab in 2016 as an intern (R.MSc. Thesis Project) with Prof. Dr. Sonja Kotz and Dr. Michel Belyk, and began PhD in 2017.


Voice adaptation and vocal learning

My work broadly focuses on the interactions among cognitive control, emotions and personality.  Understanding the influence of emotion on cognitive control is crucial as both affective and cognitive systems are intrinsically connected and enable coherent behavior in real life.  My current projects focus on how we perceive our own voice expressed with neutral (non-emotional) and emotional (e.g., anger or pleasure) intonations. I particularly answer the questions “Is this my voice?” or “Does it sound like me?” in the context of auditory verbal hallucinations in clinical and non-clinical voice-hearers.
