In this talk, I will discuss the TTbar deformation of fermionic theories. First, I briefly review the TTbar deformation of two-dimensional QFTs. And, I demonstrate the Hamiltonian analysis of the TTbar deformation of free fermion, and I show how this reproduces the deformed spectrum. Then, I explain how negative norm states could appear in the TTbar deformed fermionic theories depending on the energy-momentum tensor. Finally, I shortly summarize our results on the TTbar deformation of N=(1,1) SUSY theory..
