You can engage in scientific research or teach in a university, but the scope of employment is relatively narrow, so you should consider it carefully before making a decision.

With the same educational background, students majoring in biology are generally inferior to those majoring in computer science. However, students majoring in biology are better and there is a shortage of talents. If you transfer, the computer is a good choice. The credit level of domestic students is still in the primary stage and has not developed. Personally, I think excellent people will have a good career development in the future.
