We study the quasinormal modes of massive Dirac spinors in the background ofrotating black holes. In particular, we consider the Kerr geometry as well asthe five dimensional Myers-Perry spacetime with equal angular momenta. Wedecouple the equations using the standard methods from the literature. In thefive dimensional Myers-Perry black hole the angular equation is solvedanalytically. Using the continued fraction method, we calculate the spectrum ofquasinormal modes for the ground modes and first excited modes. We analyze, ina systematic way, its dependence on the different parameters of the black holeand fermionic field. We compare our values with previous results available inthe literature for Kerr and for the static limit. The numerical results showseveral differences between the four and five dimensional cases. For instance,in five dimensions the symmetry between the positive and negative (real)frequency of the modes breaks down, which results in a richer spectrum.
