Curriculum Vitae

My research focuses on elliptic and parabolic Partial Differential Equations. I study:

• Free boundary problems

• Integro-differential equations

• Variational problems, stable solutions

• Fully nonlinear equations

• Evolution equations

• Isoperimetric inequalities

• Classical ODEs

For a brief description of these areas, see Research interests.
