Health innovation, enabled by digital technologies to build big consumer service brands, is an incredibly interesting, complex problem to work on.
I think that the health care industry is so complex that it doesn't necessarily start with a single killer app. You go back to the early days of the personal computer - when I joined the industry, we really didn't know what the killer app was going to be.
I never claimed to be a computer engineer, but I did train as an industrial designer, and I am a consumer marketer, and I am very comfortable dealing with complex businesses and complexity in general and simplifying it - basically a systems designer.
