It's great that you're interested in a broad range of STEM subjects, and like others above have suggested, I think looking into the field of Biomedical Engineering could spark your interest. I personally am such an engineer working on the delivery systems of cardiovascular interventional treatments (i.e. catheter based therapies). I enjoy my job because I get to work on the next generation of life saving medical devices, and getting to see a patient regain their quality of life back from losing everything makes the job satisfying. Let me know if you have any questions, I'd be happy to answer them!
Alexander recommends the following next steps:
- Determine if you want to work directly with patients (i.e. a doctor or nurse) or would you like to work with medical professionals to help patients get better (i.e. an engineer)
