BHS Honors Thesis

I'm thinking about writing an honors thesis with the lab I'm currently working in, which focuses on health equity and access to care. I'm a BHS major so this aligns pretty well, but my PI hasn't had a student do a thesis before so were trying to figure out how "independent" my portion of the research needs to be. There aren't any BHS theses in deep blue, so I've looked at some psych and BCN ones, and I can't tell how involved with study design and execution the students were. Does it have to be designed start to finish by the student or is the background research and analysis the independent part? Has anyone done a thesis for BHS or anything related and could give me some guidance? I'm planning on meeting with an advisor but I wanted to hear from students too. Thank you!
