High-spin states in doubly odd ${}^{176}\mathrm{Re}$ were investigated by means of in-beam $\gamma$-ray spectroscopy techniques using the multidetector array GASP. Excited states of ${}^{176}\mathrm{Re}$ were populated using the ${}^{165}\mathrm{Ho}{(}^{16}\mathrm{O},5n)$ reaction at a beam energy of 101 MeV. Seven rotational bands have been observed and their configurations have been discussed. Alignments, band crossing frequencies, and electromagnetic properties have been analyzed in the framework of the cranking model. Signature inversion phenomena in the $\pi h_{11/2}\otimes \nu i_{13/2}$ and $\pi h_{9/2}\otimes \nu i_{13/2}$ structures are discussed. In the latter case signature inversion is traced to a large repulsive matrix element of the $p-n$ force acting in the maximally aligned $J=11\mathrm{}$ state.
