Supervision

It is possible to conduct Bachelor and Master theses under my supervision. I feel qualified to supervise work on topics from the research areas of:

  • Working memory & mental imagery 
  • Altered states of consciousness 
  • Phenomenology of drug experiences.

Methodologically I work with: fMRI, specifically task-based univariate and multivariate (MVPA) analysis methods, functional (PPI) and effective (DCM) connectivity approaches, as well as resting-state fMRI; EEG; online surveys; questionnaires on altered states of consciousness experiences; databases (e.g. the altered states database).

If you are interested in a Bachelor or Master thesis, please feel free to contact me via E-Mail. A decision to accept a supervision will depend on the fit of the suggested topic and my expertise, as well as on the resources of the Neurocomputation and Neuroimaging Unit.

It is very welcome if you suggest a topic for a BSc and MSc, while it is also possible to ask for current projects/topics which would be suitable for thesis work.

I am a neuroscientist interested in the neuronal underpinnings of human consciousness. I work with methods from the field of computational cognitive neuroscience with a focus on functional neuroimaging.

In my research I focus on :
(1) the mental representation of consciousness content (working memory and mental imagery)
(2) mechanisms underlying altered states of consciousness

Open Data

In Zusammenarbeit mit Cognitive Science MSc Studierenden, und durch eine Open Science Förderung von Wikimedia konnte ich ein elementares Datenbank-Projekt realisieren. Die Altered States Database enthält psychometrische Daten (extrahiert aus MEDLINE-gelisteten Journalen) über das Erleben von veränderten Bewusstseinszuständen, die durch diverse Induktionsmethoden (z. B. Yoga, Meditation, LSD, Cannabis etc.) hervorgerufen wurden (N=315 Datensätze; N=2168 Datenpunkte; N=52 Induktionsmethoden).
