Wildan Bagus Wicaksono

Mathematics graduate, olympiad instructor, and author.

I hold a bachelor's degree in Mathematics from Universitas Brawijaya. My current research interests lie in number theory, with recent work on counting problems involving integer matrices. Alongside my research, I teach olympiad mathematics to students from elementary through senior high school and develop problems and learning resources.

The Art of Olympiad Geometry

An Indonesian-language book that builds a foundation in olympiad geometry and introduces a broad range of problem-solving methods and perspectives. It is written for students who want to understand the reasoning behind a solution, not merely its final steps.

My path in mathematics

My mathematical journey began with olympiad geometry and gradually grew into teaching, problem writing, and the book The Art of Olympiad Geometry.

Today, I am exploring research directions in number theory while continuing to teach and develop learning resources for olympiad students.
