I'm currently a public health minor as my school does not offer a major and this entails me taking classes in both public health, epi, and biostatics. When you mean by research productivity, does this necessarily have to be in public health? I'm currently doing wet lab research because I enjoy it and its also necessary that I do so for my chemistry major. My pre-med advisor also suggested that I continue to do chemistry research when I suggested my plans in doing epi/ public health. However, I am getting some public health research through a community health research class, where I will be spending 8+ hours a week getting research experience without joining a formal lab group, so I'm not sure if I would get published.
