The last time I talked to him he was trying to write his own discrete Fourier transform so he could avoid shifting around his matrix.

Solution might be ShiftedArrays.jl which allows to do a circshift with a view. However, performance is slightly worse than an allocated fftshift.

We're currently working on wrappers doing that
