Research Area:   Model Theory, Differential and Difference Algebra

Research Profile
I am interested in the interaction of geometric stability theory (a branch of model theory) and differential (and difference) algebraic geometry. This includes the study of the geometric Galois theory associated to "logarithmic" differential equations. I am also interested in the study of the model theoretic properties of theories of fields with general types of (Hasse- Schmidt) operators.
