I'm a student applying for the 2023 fall Ph.D. program.
While doing my master's degree in 2022, I transferred to A University from B University.
The reason was that I wanted to learn both bioinformatics and biological experiments when I was applying to graduate schools for a master's degree. The previous PI at B University told me he is doing both in his lab, so I decided to get in. However, it turned out that the main focus in his lab was something else, which is different from bioinformatics. Also, I was able to learn only basic experimental skills, such as cell subculture and transfection. I decided to move to A University where I can learn advanced experiments and corroborate with bioinformaticians at other universities.
Now I'm worried about that the admission reviewers would consider it a bad decision, thinking 'this student will easily quit the Ph.D. program if he is not satisfied'. What words should I use when I defend myself from this situation?
