We investigate D-branes in cosmological models. In particular, we examine Misner space, which can be constructed as a Lorentzian orbifold. This space includes big crunch/big bang singularity and closed time-like curves. We compute annulas amplitudes for open strings on D0-brane and D1-brane and find imaginary part of the amplitudes. The imaginary parts are interpreted as the rate of open string pair creation on D0-brane and as the emission rate of closed strings from D1-brane. We also compute 2{yields}2 scattering amplitude of open strings and examine its divergence structure.
