  We present our study of $\pi-N$ scattering in the iso-spin $I=3/2$ channel
for the first time at the physical point. The calculation is performed using
$N_f=2+1+1$ flavors of twisted mass fermions with clover improvement at
physical pion mass. We compute energy levels for the rest frame and moving
frames up to a total momentum of $|\vec{P}|=\sqrt{3} \,\frac{2\pi}{L}$, and for
all the relevant ireducible representations of the lattice symmetry groups. We
perform a phase-shift analysis including $s\,(\ell=0)$ and $p\,(\ell=1)$ wave
phase shifts assuming a Breit-Wigner form and determine the parameters of the
$\Delta$ resonance.
