Research Interests

In the mathematical research, I intend to improve the general understanding and to broaden the current knowledge of various modern topics in mathematical analysis , including application to (stochastic) partial differential equations and mathematical physics.
In my work, I enjoy using different perspectives and approaches to study and to develop solutions to current important mathematical problems. For this, I don't hesitate using abstract views from functional analysis, microscopic views by using tools from stochastic analysis, and optimal transportation.
More precisely, I regularly contribute to the following topics.
  • Eigenvalue problems and isoperimetric inequalities with main focus on the Fundamental gap conjecture for Schrödinger operators
  • Calculus of variation with application to PDEs
  • Regularity theory in nonlinear Evolution problems
  • Non-existence and long-time stability in nonlinear Evolution problems
  • Homogenization and domain perturbation
  • Stochastic analysis with application to stochastic (partial) differential equations
  • Optimal Transportation
