I met someone who graduated from Firat University in Turkey, and claimed to have published 60 journal articles in his 3 years of PhD studies (2015-2018).
Although I haven't studied in Turkey or Asia(Malaysia, China, etc) before, this throws me into confusion and doubt, as I know this is no way near possible, at least in places I have studied (Europe and the UK), particularly in his field of study (Applied Mathematics).
Checking through his scholar page, and follow up to the articles, I noticed first author is the professor that supervised his work in majority of his works. I also noticed about two other PhD candidates in his connection that made such an "outrageous" publications, thus a high Google scholar index score.
I didn't want to dig further with the guy to know how that was possible, as he might see it an attack on his personality.
Out there, I know people might have some idea how is the PhD process in Turkey.
