One big problem in the healthcare in africa, is the cost and complexity of blood tests. And we know lab-on-chip technology can fix that, but nobody is working on that, because of "business model" problems.
But that's one thing a successful theranos could do, and foreign policy is important at that.
This is complete misdirection though. It has no relevance to a biotech company. If the test is cheap and easy, then charities and governments will carry it into Africa. There's no fiscal reason to pay people with foreign policy experience, because it has nothing to do with foreign policy. Its miles away from being relevant to the central technology, and African charity is not how one achieves a multi-billion valuation.
