We present a study of the early UV/Optical emission of the stripped-envelope     supernovae based on a one-dimensional, Lagrangian model that      solves the hydrodynamics and radiation transport in an expanding         ejecta. The models are compared with observations to constrain the physical     properties of the progenitor star, such as radius and mixing of radioactive nickel synthesized during the explosion. In particular, we present models for     the early emission of the type IIb SN 2011dh and the Type Ib SN 2008D.
