The recent advances in theoretical studies of atomic resonances by using the method of complex-coordinate rotation (CCR) are reviewed. The recent applications of CCR include the investigations of doubly excited states of H and He under the influence of external electric, magnetic, and combined electric and magnetic fields, as well as photoionization of He, with and without the presence of external electric fields.
