Biography

I'm a retired computer science researcher and software engineer. My areas of focus included systems and networks, mobile and edge computing, human mobility modeling, security, and privacy.

In the last ten years of my career I built large-scale privacy infrastructure at Google. I was previously a researcher at Bell Labs, AT&T Labs, and IBM Research. I also held leadership positions in several startup companies.

I'm an ACM Fellow and IEEE Fellow. I hold PhD and MS degrees in Computer Science from the University of California at Berkeley, and a BEng in Electrical Engineering from McGill University. I was born and raised in the Dominican Republic.

My CV contains a more complete career history. I'm also an avid sailor. My sailing résumé outlines that experience.
