Vahidnia received his BSc in mathematics from Sharif University of Technology and his MA in philosophy from Shahid Beheshti University. He won a gold medal at the Iranian Mathematical Olympiad in 2007. He is also a winner of the silver medal in national computer Olympiad in Iran. Although some media reported he was the "international mathematics Olympiad winner", he didn't compete at any international mathematics Olympiads.
Vahidnia got significant media attention when he was a student in the Department of Mathematics at Sharif University of Technology for his face-to-face criticism of Iran's supreme leader on October 28, 2009, during a meeting between Ali Khamenei and students. During this meeting, Khamenei was challenged by Vahidnia in what was called "an unusual encounter". The event was being broadcast by Iranian state-run TV. That made the authorities stop airing the programme.
