One of the expressions you can often hear at American academic conferences or international meetings is
“won’t ~ until.”
In a literal sense, this means “will not do ~ until ~ happens,” but the natural interpretation is “we’ll do it once ~ happens,” which carries a positive meaning that the action will be carried out when the condition is met.
Because it can express a planned and responsible attitude like this, it is used very often in academic contexts such as paper submissions, research progress, and formal presentations.

Three example sentences
-
We will start the study once IRB approval is granted. We won’t start the study until we get IRB approval.
-
We plan to submit the paper once all the data has been collected. We won’t submit the paper until all data is collected.
-
We will make the presentation once the FDA issues an official statement. We won’t make any announcements until the FDA makes an official statement.
“Won’t ~ until” is not simply a refusal; it is effective for conveying a professional intention to act later, once preparations are complete.
It is a good expression that can inspire trust in academic presentations or paper reviews, so if you learn it naturally, it will be useful in real situations.
