Biography

I am a computer science researcher and software engineer. My areas of focus have included systems and networks, mobile and edge computing, mobility modeling, security, and privacy. Most recently I worked at Google, where I built large-scale privacy infrastructure. I was previously a researcher at Bell Labs, AT&T Labs, and IBM Research. I have also held leadership positions in several startup companies.

I am an ACM Fellow and IEEE Fellow. I served on the board of the CRA Committee on Widening Participation in Computing Research. I hold PhD and MS degrees in Computer Science from the University of California at Berkeley, and a BEng from McGill University. I was born and raised in the Dominican Republic.

My CV contains a more complete career history.


Recent projects

At Google I helped develop and maintain Zanzibar, their global authorization system. Zanzibar constitutes critical privacy infrastructure at planetary scale. It controls access to trillions of data objects managed by products used by more than a billion people every day, including Calendar, Drive, Maps, Photos, and YouTube. It guarantees external consistency while serving millions of authorization requests per second with 95th-percentile latency under 10 milliseconds and availability above 99.999%.

In my seven years on the Zanzibar team, I improved the system's scalability, reliability, and security as its workload and use cases grew. I also served on the on-call rotation that responded to production issues 24x7. Finally, I led the publication of an experience paper that has inspired a number of authorization systems outside Google.

My CV outlines other previous work.
