I have a BS in Biology graduated 2012 and now working at a water treatment plant as a lab tech. I am interested in Epidemiology but I heard that I need to get a Masters degree for this. I saw a job posting here in MN that a person can have a BS but just needs experience. My question is, where can I get experience? Volunteer where? Doesn't matter if I don't get paid I just want the experience so I can get in the field. Or do I absolutely need a Masters degree? Thanks!
