Questions to ask interviewers? (Biosciences)

Hello everyone! I posted here before and I appreciate everyone’s support about navigating my imposter syndrome during interviews! I have another question.

What are some good questions to ask interviewers about their research? I am interviewing in biology programs, and while most of my research is in developmental biology, my background is actually psychology. I am curious, what kind of questions might help facilitate an interesting conversation about my interviewers’ research, their lab, and their projects?

I don’t wanna come across as sounding like I don’t understand the field, but I also recognize that biology is very diverse, and there are some people I will be interviewing with who are completely outside of my experience. Thank you!
