不太感兴趣老师的研究方向，这么说可以吗？

之前套的校友老师回邮件说了自己做的方向，然后给paper让我看，但我看了以后觉得太理论了，这么回复他可以吗？

I have read your paper roughly these days and it indeed pays more attention to academic computation. To be honest, it was kind of difficult to
understand the meaning of equations and the derivation for me. Moreover, I still feel more interested in practical application. Therefore, I think
there are other students more suitable for your research group.
