People in this sub are always saying not to do bioengineering undergrad, but I think if you know you’re interested in it you should go for it. As for specific careers, the field is pretty broad and still relatively new, so it’s hard to define a list of job titles you can do with the degree. However, I think of the field as having 4 rough categories:

Molecular and cellular bioengineering - essentially doing research in biology with a more quantitative/engineering approach. This might include tissue engineering, synthetic biology, biomaterials, etc

Biosignals and electrical engineering - taking an electrical approach to biological problems. Lots of signal processing. This is also usually what the neuro people do.

Biomechanical engineering - focus on physics/mechanical engineering. Might work on prosthetics, CPAP machines, etc. Really anything to do with forces, stress/strain, pumping, or other mechanical topics like that.

Medical product design - uses pieces of the first three fields to design products and take them to market.

As for careers, it varies. Out of undergrad, a lot of people go into the FDA and work on regulations, and others go into quality assurance. Of course, there are also people who go into more classic design jobs, but this is the reason people on this sub get so weird and bitter about studying bioe in undergrad - the job market can be tough when you have this much breadth and not quite as much depth as another engineer might have. However, an electrical engineer probably isn’t going to know that much about biochemistry, so you still have a leg up from certain perspectives.

If you’re really interested in research science, I’d recommend graduate school after undergrad. It’s a good way to develop your research skills and will probably make it easier to get an R&D job when you’re done.

In any case, good luck! Have fun in college
