The observation of neutrino oscillations in the 1990s unambiguously signal new physics beyond the standard model. On the one hand, the very precisely measured neutrino oscillation parameters are becoming more and more sensitive to new physics; on the other hand, however, the absence of any definitive signals of new resonances at colliders strongly suggests the scale of new physics be possibly above the weak one. Together, they render studying neutrino physics model-independently in EFTs possible and imperative. In this talk, based on our recent work, I will present how to utilize neutrino non-standard interactions (NSIs) as indirect probes of new physics at current (such as Daya Bay, Double Chooze, RENO, T2K and NOvA) and upcoming (like JUNO, T2HK and DUNE) neutrino oscillation experiments. Time permitting, implications on NSIs from the recent observation of the CEvNS events as well as precision measurements of Neff will also be discussed. 个人简介：杜勇，中国科学院理论物理研究所博士后，2020年博士毕业于马萨诸塞大学阿默斯特分校。目前主要从事于有效场论的各种现象学应用以及高阶电弱修正的精确计算。 Tecent meeting: https://meeting.tencent.com/dm/MPT9MBgByNpN Meeting ID：745-281-268
