let me slide in my own perpsective here based on what I see. you like technology as well it seems, look into healthcare information mgmt, it puts business, healthcare and this whole patients records in focus, things like HIPAA, PACs and RIS areas are massive. they are growing PACs from beyond rdiology to other fields as well, and there is a skill shortage. it can be a career in public health policy, consulting, healthcare mgmt and even healthcare software and device manufacturers like GE health, McKesson etc.
Health Informatics is a great field to get into indeed... actually, it's what I'm contemplating with the program I mentioned in my first post. As you've pointed out, there's a lot of potential in the field and based on what I hear from other colleagues, the next 10 years or so are going to be crucial for people wanting to establish careers in the field.
