I am a Google Fellow and the head of the office of Cross-Google Engineering (xGE) which is responsible for company-wide technical coordination. In my time at Google I have worked as a VP of Engineering in the Core and Maps teams, and as the technical leader in areas such as Google Search and the design of Google‘s computing platform. I have co-authored research articles in areas such as computer architecture, energy efficient computing and distributed systems. I also co-wrote "The Datacenter as a Computer", the first textbook to describe the architecture of warehouse-scale computing systems, now in its 3rd edition. Before Google I was a member of the research staff at Digital Equipment Corporation and Compaq, where our group did some of the pioneering research on modern multi-core microprocessors.

I am a Fellow of the Association for Computing Machinery, and the American Association for the Advancement of Science, a member of the National Academy of Engineering and of the American Academy of Arts and Sciences, and the recipient of the 2020 ACM/IEEE Computer Society Eckert Mauchly award. From 2013-2019 I have served on the National Academies' Computer Science and Telecommunications Board.

I hold B.S. and M.S. degrees in Electrical Engineering from the Pontifícia Universidade Católica of Rio de Janeiro, and a Ph.D. in Computer Engineering from the University of Southern California.

Professional service

I have a limited time budget for external professional activities but have enjoyed many opportunities to work with the academic comunity and other professional organizations.

Committees and Boards

Between 2013 and 2019 I served as a member of the Computer Science and Telecommunications Board, a division of the National Research Council

Select press articles

Popular Science named the COVID-19 Exposure Notification Technology co-developed by Google and Apple the Innovation of the Year in 2020.

Wired magazine has writen an article about our latest StreetView cars and related computer vision technology. The accompanying video featuring some of my colleagues is worth a watch.

A 2012 Wired article interviews me on the concept of Warehouse Computing.

Wired has written other articles on our work at Google, including one on datacenters and a profile of my colleagues Jeff Dean, Sanjay Ghemawat, Urs Hoelzle and me.


I play guitar and bass guitar in Catherine Warner's new album, Loss and Found.

In 2020 I received the 2020 Eckert-Mauchly Award, given by the ACM and the IEEE Computer Society for pioneering the design of warehouse-scale computing and driving it from concept to industry.

As technical lead of the Google Platforms team between 2010-2015, I started a project aimed at hardware acceleration of machine learning applications which resulted in the Tensor Processing Unit (TPU), a custom ASIC that powers several ML systems at Google, including image understanding from Street View.

I wrote the foreword for the 5th edition of Hennessy & Patterson's Computer Architecture: A quantitative approach, the classic textbook on computer architecture which was first printed when I was a graduate student.

Co-authored the NRC report: The Future of Computing Performance: Game Over or Next Level?, which describes how underlying circuit technology is no longer yielding the year-over-year improvements we have been accustomed to since Moore's law was "enacted", and what that means to the future of computing.

A short essay on innovation that I wrote for an internal Google audience was subsequently published in Google's re:Work blog. See The Roofshot Manifesto. It was then added to the 2nd edition of E.Schmidt's and J.Rosenberg's How Google Works.

I co-wrote the official SIGARCH/TCCA best practices document for ISCA program chairs.

I was the guest co-editor of IEEE Micro Jul/Aug 2010 special issue on Datacenter-scale Computing
