In this talk, we first recall the development of the nonstandard singular integral operator introduced by Cohen, and then introduce our recent results concerning the mapping properties of this operator, such as

1. Lp boundedness and weak type endpoint estimates when the kernel satisfies minimal size condition;
2. Quantitative weighted estimates when the kernel satisfies a size condition;
3. Lp estimates for the associated maximal singular integral operator.

 This is a joint work with Prof. Tao Xiangxing, Prof. Xue Qingying and Dr. Wang Zhidan.
