My research focuses on Integrable Systems and their algebraic, geometric, and field-theoretic aspects. For more details, please see my publications and my short CV.
I help students learn mathematics by mixing interactive elements (live polls, group work, explorables) with traditional lecturing. The guiding principle in my approach to teaching is discovery-based learning.
I'm passionate about communicating my love of mathematics and science to the wider community. Below you can get glimpses of my outreach activities: public lectures, SciArt projects and social media (twitter, YouTube). Feel free to get in touch with me if you would like to collaborate with me or invite me to talk at your event/School.
