(Semi-)leptonic D decays at BESIII

BESIII has collected 2.93 and 6.32 fb^-1 of e+e- collision data samples at 3.773 and 4.178-4.226 GeV, respectively. We will report precision measurements of fDs, |Vcs| and test of lepton flavor universality by studying the leptonic decays of Ds -> l+nu with tau+ -> rho+nu, pi+nu, and e+nunu. We will also report the studies of Ds -> pi0pi0e+nu and KSKSe+nu, inclusive Ds semileptonic decay, updates of D-> Ke nu with a new method.
