Short presentation
My primary interest in mathematics concerns the regularity theory for partial differential equations, specially the study of the regularity of solutions and their level sets. The topic lies in the interface of analysis and geometry. I have a great enthusiasm in exploring new topics and developing novel techniques that combine these areas. Particularly, I am interested in free boundary problems and homogenization problems.
