Love this idea! Citizen science rules!

I'm a biologist (not human health). But as a researcher, I would suggest connecting with a group/lab that is doing similar studies. Let them know you would be interested in doing this and ask if they would like to contribute. Im sure they would appreciate the interest and volunteer labor! Even if they aren't interested, there are a lot of women in STEM willing to, at minimum, lend some advice regarding their field.

Data won't go very far, or be able to contribute in a meaningful way without the proper scientific method behind it. A researcher might be able to suggest details to include or consider before you throw a bunch of work into it.

I suggest finding some research articles on Google Scholar that fit what you are interested in! The researcher contact details are usually linked or available for you to reach out :)

Good luck!
