Learn
Ideas, problems, and courses that are shaping how I see mathematics.

I follow mathematics wherever curiosity and beauty lead — learning, teaching, and writing along the way.

Curiosity
without borders.
I hope to study any mathematics that reveals beauty: in an idea, a proof, a pattern, or an unexpected connection.
My interests are still growing. I would rather let beautiful questions lead than draw boundaries around them.
