Last year, I applied to a university which is in Europe so a research statement is a crucial part of the application. I was interviewed by two faculty members and then finally got a rejection letter.
In my research statement, I had a particular idea and described a roadmap for it, though I did not get into technical details. But the idea was there and clearly stated. Recently, I came across a publication where the title is the same as my idea (wording is a little bit different) and is co-authored by one of the guys who interviewed me.
The publication has technical details which were not part of my research statement.
I believe there is no clear proof here whether my ideas got used or not.
My questions are:
is this suspicious?
is this valid and acceptable?
