Last year, I have applied to a university which is in Europe so a research statement is a crucial part of the application. I have been interviewed with two faculty members and then finally got a rejection letter.
In my research statement, I got a particular idea and described a roadmap for it. Though I did not got into technical details. But the idea was there and clearly stated. Recently, I came cross a publication the title is same as my idea (wording are little bit different) and co-authored by one of the guys who interviewed me.
The publication has technical details which were not part of the 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?
