I still hope it will be no problem that I am welcome to ask you some academic questions in the future.
当你是请求对方时, 还是不需要把无论如何这种话说出来的, 你只要表达你的希望就好了; 所以不要有 anyway这种话, 对方会感觉很不好~~ 你用still就已经足够表现你的心意了~~
比如你在这前一句是说, 尽管你不再担任我们的老师了, 那你後面接这一句就很完美了~~
整句给你:
Although you will not teach us anymore, but I still hope it will be no problem that I am welcome to ask you some academic questions in the future.

以上, 希望有帮助~~＾0＾
