In this talk, we give an explicit description of Kisin variety parametrizing Breuil-Kisin modules associated to certain families of potentially Barsotti-Tate deformations of modulo p Galois representations of dimension 2. We explain how we may deduce the associated deformation ring in non generic new cases. This is joint work with Xavier Caruso and Agnes David.
