Research Interests

Mixing image Mixing image

My research concerns "Theoretical Applied Math" using tools from partial differential equations and probability. More specifically, I've worked on a variety of problems related to anomalous diffusion, anomalous dissipation, coagulation, fluid mechanics, homogenization, Q-tensors and mixing.
