Suspects have also been raised that Cho's daughter was an intern at Gongju University and named her thesis author.

After attending an internship program at Gongju University's Biotechnology Laboratory in 2009 when he was a third year student at Hanyoung Foreign High School, he was named 'Third Author' in his article on genetic analysis of red plants.

Mr. Cho explained that the article was published directly in English by the International Society in Japan, and was written as 'third author' in the presentation, not the paper.
