Work

I think about how measures should be designed mathematically to measure what researchers want them to.
  • I applied Information Theory to measure how much "information" humans process unconsciously.
  • I worked on confidence-weighted majority voting as a baseline to measure success in group discussions.
  • Currently, I am working on measures of metacognition (How good can you evaluate your confidence?) and inter-rater consistency (How similar are two classifiers, e.g., human and deep neural networks?).

Mediation

I am trained as a certified mediator (IMI Mediator). If a conflict is developing in your work group, I can create a safe environment to find a fair solution. Send me an email.


Working with me (Code of Conduct)

If you are a student in Cognitive Science or related fields and want to work with me, typically after participating in my lecture or seminar, feel free to send me an email.

When you work with me, I will try to make you comfortable with the sometimes scary math formulas or writing commands in the console. You should never feel left alone with these things. I will also be as explicit as possible about the tasks I give to you. This way, I will try take away insecurities.

On the flip side, I expect you to bring high intrinsic motivation: Be on time for our meetings. Take notes. When you show me your results, don't just show me the last-minute version but double check them and consider how you want to present them to me.

If you invest enough time into working with me, I will give that back to you in mentoring. If you feel comfortable with it, I am also happy to talk with you about self-management and give you coaching advice.
