how I got here

Maths and music, from the start

I didn't come to mathematics from one direction. I trained as a musician (voice is my main instrument) and spent years performing on stage and screen before I ever stood at the front of a classroom. At the same time I was pulled towards the analytical side of things. I did coursework in engineering and computer science, and then a full teaching qualification that covered both maths and music. Living in both worlds has never felt like a contradiction to me. It's just how I think.

That turns out to matter more than I expected. A lot of students arrive convinced they're "a creative person, not a maths person," as if the two rule each other out. I know from experience that they don't. And students seem to find that easier to believe coming from someone who's spent as much time on a stage as at a whiteboard. Performing also taught me things that have little to do with music. For example how to tell when someone's quietly lost, and how to reach for a different explanation when the first one hasn't landed.

Mostly it means there's usually more than one way in. If a student can't connect with me through the maths, they can connect through something else first. That tends to make the maths itself feel a good deal less intimidating.

Experience overview

2026

Tutoring in Zurich

After moving to Zurich, I decided to focus on one-to-one tutoring. This allows me to focus on the specific gaps individual students have to address their needs.

2024

Sabbatical in Cambridge, Massachusetts, USA

I spent a year living in Cambridge, Massachusetts, where I worked one-to-one with students from different backgrounds and ability levels. Evenings went to a musical production of Cabaret: same year, same person, and neither half felt out of place.

Upper-secondary mathematics teacher

As a full-time classroom teacher in private and municipal schools in Gothenburg, I taught maths to whole classes aged 16–19, running exam preparation and supporting students who had fallen behind and needed to retake a course and regain their footing.

Master of Arts in Education

I earned a Master of Arts in Upper Secondary Education at the University of Gothenburg, specialising in Mathematics and Music and obtaining a full teaching qualification.

Earlier

International & STEM experience

I've taught in South Africa, worked in STEM education at the Universeum Science Center, and trained as a musician and performer. My artistic background allows me to relate to students when they're stuck.
