We consider periodic homogenisation problem for two dimensional generalised parabolic Anderson model, a model problem of a singular SPDE beyond Da Prato - Debussche trick. The goal is to understand how the two singular limiting procedures, homogenisation and renormalisation, interact with each other. One key ingredient is to identify a suitable ansatz uniform in the homogenisation parameter in a nontrivial SPDE setting. Based on a joint work with Yilin Chen (PKU) and Ben Fehrman (LSU).
