I am looking for Undergraduate 4 year degree in – Epidemiology and Biostatistics and Neuroscience. ALL three. Which will narrow down the college search.
That’s too much. You don’t need to major in three areas - and it may be difficult to nigh impossible at universities that even offer those majors. Neuroscience is a major that can be relatively demanding in terms of course load and sequencing, so trying to double major in and of itself is hard. Trying to triple major? Not only that, it’s completely unnecessary.
That said, epidemiology and biostatistics are majors that are generally studied at the graduate level. They tend to be a bit too narrow for undergraduate study. The undergraduate corollaries are a public health/community health/health and society major and a statistics major. Biostatistics is simply statistics applied to health and medical problems - you’re using the same tools and models, you’re just using them in a specific field. So statistics (maybe with a minor in biology or health) is a perfectly acceptable and equivalent alternative to majoring in biostatistics, a major that doesn’t exist for the vast majority of undergrads.
Epidemiology is only one part of public health, which has five major fields (the other four are biostatistics, environmental health sciences, health policy and management, and health education/health promotion). The idea of undergrad is more breadth and foundational work than depth, which is why it makes more sense for an undergrad to major in public health than epidemiology. But there are lots of other alternatives - math or stats are good majors because epi is highly quantitative; biology or chemistry can be good majors too.
There’s only one university I can think of that has an undergraduate epidemiology major - the University of Rochester. But they don’t have the other two: they have a brain & cognitive sciences major (which is probably as close as it gets for neuroscience) and a statistics major (which, like I said, is functionally the same but just doesn’t focus on health specifically). Even the vaunted Johns Hopkins only has a public health sciences major for undergrads. USC has something called health promotion and disease prevention studies, but that sounds like a mix of epidemiology with a bunch of other public health topics (so, essentially, a slightly narrower version of public health).
Juillet is correct that Rochester may be the only school with an epidimiology undergraduate major. Most people study Epi at the graduate level Also your hope to get a degree in all three probably cannot be accomplished. There are too many courses to complete. You could possibly do two of the three but they are often across different schools so may be difficult to coordinate.
Note that if you study Epi you will take a number of statistics courses and will get a good basis in stats. My Daughter was an epi major at Rochester and often said she took enough Math to qualify as a math teacher or statistics teacher.
If you are interested in Rochester note that they offer a 3/2 program whereby you can complete an undergraduate Epi degree and public health masters in five years. My daughter completed her undergraduate Epi degree and Public health masters in 5 years. Note that if you do epi as an undergraduate major and choose a masters you probably don’t want it in Epi because you will have already taken most of the relevant Epi courses.
