Is teaching theoretical material (sports nutrition) to male and female students at the Faculty of Physical Education, Assiut University, permissible or impermissible for my wife?

Mixing in universities today is a reprehensible act that leads to corruption and discord. The original principle is to separate male and female students. A wife working in a mixed faculty is permissible if she is safe from temptation and adheres to the Sharia controls such as the legal hijab, lowering the gaze, and avoiding illicit seclusion (khalwa) and prohibited mixing. However, if she is not safe from temptation, or if her work necessitates seclusion with men or prohibited mixing, then it is not permissible. It is preferable for her to work in teaching girls.
