Could we say "discuss future work"?

I am writing my thesis. I have a sentence

Finally, we conclude the thesis and discuss future work in Section 6.

My friend told me that "discuss future work" was not appropriate, and I could not find the usage of
"discuss future work" on the internet. Shall I adopt "discuss the directions for future work"?
I cannot distinguish "discuss future work" with "discuss the directions for future work".
Could you give me some suggestions? Thanks in advance!
