    Teaching

    As a major part of the University`s societal task, high quality teaching and outreach is important. I have an active learning approach to teaching, and enjoy the opportunity to communicate and discover new views and questions on an engaging subject. I have fulfilled my teaching/compulsory work part of my PhD contract.

    I have completed the Pedagogical course for PhD candidates
