I was a strong research fit at the programs that accepted me. I do research in a fairly small area, and it seems like these particular faculty really liked applicants with relevant experience since it’s somewhat rare (compared to e.g. depression or anxiety). I applied to other labs where my interests/experience weren’t as compatible and did not get interviews or offers. That being said, the research I’m currently working on is quite different from anything my advisor has done previously, although still in the same broad area. My advisor is open to exploring new ideas as long as they’re in her general area of expertise.
I would recommend asking for feedback from your POI herself rather than the admissions director. It sounds like she wanted to admit you, so the explanation of advisor fit might just be a generic explanation that they give to everyone. It could be that your POI didn’t get a student because too many faculty wanted to accept students, or a funding issue, or any number of other reasons.
I agree with the previous poster! A clinical psych PhD sounds perfect for you. They are generally heavily research-focused, and many people with clinical psychology PhDs are primarily researchers.
The flexibility part is big too- I love research, but chose a clinical PhD because having a research career is so uncertain and I wanted to have options.
I would expect that Ryerson sent their first acceptances a while ago since they typically send them around early February. Last year the first round of rejections came out around now.
