讨论 is different from 研究
I want to say ‘研究工作’, but will it mean the same thing if I just write ‘讨论工作’?
you can say"我在研究工作" sometimes ,that means "you are thinking aout your work alone" ,also we usually say "我们在研究工作" ，means "we are talking about our work ,maybe talking ,maybe discussing"
我和某某人在研究工作，Somebody and I are talking bout/discussing work.
讨论 means discuss. you can but 讨论 sth with somebody.
eg.我和刘明在讨论今天的作业。Liu Ming and I are discussing/talking about today's homework.（here discuss is better than talk about）
我们讨论了一下当前的国际形势。We discussed the current international situation.
