Olli Saari's Homepage

I received my PhD from Aalto University in April 2016. My advisor was Juha Kinnunen, the research group "Nonlinear Partial Differential Equations". During the spring term 2017, I am a postdoctoral fellow at the MSRI in Berkeley.

My research is in the interface of harmonic analysis and PDE. My doctoral thesis was about parabolic PDE and weighted norm inequalities. In addition to that, I have studied potential theory of the p-parabolic equation and topics related to maximal functions and spaces of BMO type.
