Biography
I received my Diplom in Psychology from Humboldt-Universität zu Berlin in 2011. In my thesis, which was supervised by Florian Schmiedek (DIPF), I explored inhibition using a diffusion model approach. During my studies, I focused mainly on neurocognitive sciences and the intersections of computer science and psychology; spending my last year abroad, first in the lab of Eric-Jan Wagenmakers (University of Amsterdam), then in the lab of Roger Ratcliff (The Ohio State University). I returned to Berlin, where I worked for Birgit Stürmer (Humboldt-Universität zu Berlin) before starting my DPhil studies in the ACC lab at Oxford University in the fall of 2011, where I was supervised by Nick Yeung. In fall 2013, I spent several weeks visiting the lab of Stanislas Dehaene at Neurospin, Paris. I successfully completed my DPhil studies in June 2015 and then started my first postdoctoral research position with Benedetto De Martino (2014-2016 Cambridge University, 2016-present University College London). In May 2017, I began my second postdoctoral research position in the lab of Sam Gilbert (University College London). I started my Sir Henry Wellcome Postdoctoral Fellowship in the fall of 2018.
Research Summary
I am interested in how the human brain is capable of forming metacognitive judgements. Metacognition is usually defined as thinking about one’s own thoughts and actions. This important and ubiquitous ability serves to optimise behaviour in countless situations, ensuring that we have control over what we are doing. If we lose control, metacognitive warning signals ensure the additional allocation of attentional resources.

For example, with regards to decision making, we can be more or less sure that decisions we are making are right or wrong. This becomes present in gambling: people are more willing to bet money on decisions they are confident are right, such as being certain their favourite football team will win a game.

Metacognition is usually investigated through confidence judgements. I am interested in how such confidence is related to the internal values and preferences on which we base our decisions.  My main research questions are (a) how are metacognitive signals formed and (b) how can they be utilized for cognitive control. I am studying these questions using both behavioural and neuroimaging experiments (EEG and MRI), as well as with computational models.
