Immanuel van Santen (geb. Stampfli)

About me:
My main research subject lies in the field of (affine) algebraic geometry. A particular emphasis of my research lies in the study of the group of algebraic automorphisms of the affine space. In my recent research, I turned my focus to algebraic embeddings of (affine) varieties.
