The epoch of reionisation is a key epoch in the history of our Universe, during which the first stars and galaxies formed, but it is extremely challenging to observe. Better characterisation of the EoR can reduce uncertainties on cosmological parameters like the neutrino mass. Here I describe how kSZ statistics, in particular the kSZ trispectrum and cross-correlation with CMB lensing, can be used for this purpose.
