Daniel Halpern-Leistner

Assistant Professor

Department and Program Affiliations: 
Mathematics

Academic focus:
Algebraic geometry, which studies systems of polynomial equations in many variables. There is a beautiful and deep connection between algebraic properties of a system of equations, and geometric properties of the shape defined as the set of solutions of the equations.

Current research project:
The "beyond geometric invariant theory" program. One of the oldest questions in algebraic geometry is the problem of moduli, which asks how the geometric properties of a shape change as one varies parameters in the equations which define that shape. My research focuses on incorporating modern methods to develop a new approach to moduli problems.

Previous positions:
