I am the co-founder and CEO of Oscar Health. Previously, I was the chief scientist of what was at one point the largest social gaming company in Latin America. I used to work as a senior investment associate at Bridgewater Associates, the largest global macro hedge fund in the world. Before that, I worked at McKinsey & Company. I also once was a visiting scholar in computer science at Stanford University. I wrote a whole bunch of publications. Among them was a paper on an algorithm we called Eigentrust, which enables a convergent, distributed calculation of trust scores in dynamic networks. It is among the most-cited computer science papers since it came out in 2003.
