It is desirable that the audience is familiar with Modern Probability Theory and some tools in Stochastic Analysis such as martingales and stochastic differential equations. But I will try to briefly explain these in my course. For example, Parts I and II of my course given at Yau Mathematical Sciences Center from March to June, 2022 fit to this purpose; see slides of Lect-1 to Lect-20 posted on the web page of YMSC.
I explain our recent results on the derivation of interface motion such as motion by mean curvature or free boundary problem from particle systems in some details. The core of these results was presented in my talk at vICM2022 , .

Funaki Tadahisa was a professor at University of Tokyo and then at Waseda University in Japan. His research subject is probability theory mostly related to statistical physics, specifically interacting systems and stochastic PDEs, whose importance increases as several Fields medals are given to this area.
