<p>I can not comment on the job prospects/salary of ECE, but with a Biology degree you have a very wide range of options, very few of which are high paying. If you do choose to go the Bio route, I highly suggest you get an advanced degree, since B.S./B.A. Biology holders are a dime a dozen and likely end up in an unglamorous, low paying job. Also, you might want to look into a ChemE degree since it’s very easy to tailor the curricula to overlap with the interests you mentioned. It is lacking in programming, but a minor in CS could satisfy that. Just be warned that the degree of rigor and time needed for an engineering degree is high compared to a Bio degree.</p>
