Biography

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

I recently retired from 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 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 am also an avid sailor. My sailing résumé outlines that experience.
