Luiz André Barroso

Google Fellow & VP of Engineering, Geo Platform


I am a Google Fellow, and the VP of Engineering for the Geo Platform team, the group responsible for collecting and curating maps, local and imagery data that powers our consumer products (such as Google Search and Google Maps). My technical interests that range from distributed systems software to the design of Google's computing platform. While at Google I have co-authored some well-cited articles on warehouse-scale computing, energy proportionality and storage system reliability. I also co-wrote "The Datacenter as a Computer", the first textbook to describe the architecture of warehouse-scale computing systems, now in its 2nd edition. I was previously 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 architectures. Some of those multi-core processors also use variants of the ring-based cache-coherency interconnects that were the subject of my doctoral research.

I am a Fellow of the Association for Computing Machinery (ACM) and the American Association for the Advancement of Science. I was the program chair of ACM ISCA'09, a keynote speaker at FCRC'11, SIGMOD'10, ASPLOS'09, and a National Academy of Engineering Gilbreth Lectureship awardee in 2012. I am currently serving at 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.

Luc Vincent

Engineering Director, Geo Imagery


Luc Vincent joined Google a decade ago to work on the Google Books project. While he was ramping up Google's OCR efforts, he got involved in an early stage project whose goal was to capture a large amount of street level imagery and make it universally accessible and useful. Under Luc's leadership, this project became Google Street View and launched officially in May 2007. Since then, Luc's scope has expanded to include imagery captured from a range of sources, including people on the ground, airplanes, satellites, and more. He is currently an engineering director responsible for all Geo Imagery in Google's products. His team is focused on making all this imagery data and derived information broadly useful to users around the world, from end-users on a mobile phone to geo scientists researching climate change.

Before Google, Luc spent many years at Xerox Corporation, including a stint as Area Manager at the prestigious Xerox Palo Alto Research Center (PARC). He also worked for a while in startup-land, with mixed success. Luc holds dozens of patents and has over 60 publications in the area of computer vision and image analysis. He has served as an Associate Editor for the IEEE Transactions on Pattern Analysis and Machine Intelligence (PAMI), and for the Journal of Electronic Imaging. He has also chaired a number of IEEE, SPIE, and ISMM conferences and been invited as a keynote speaker on countless occasions.

Luc earned his B.S. from Ecole Polytechnique (France), M.S. in Computer Science from University of Paris XI, and PhD in Mathematical Morphology from Ecole des Mines de Paris. He was also a postdoc in the Division of Applied Sciences of Harvard University in 1991.

Rebecca Moore

Engineering Director, Google Earth, Earth Engine & Outreach

Rebecca Moore is Director of Google Earth, Google Earth Engine and Earth Outreach. She initiated and leads the development of Google Earth Engine, a new technology platform that puts an unprecedented amount of satellite imagery online and enables scientists to conduct global-scale monitoring and measurement of changes in the earth’s environment.  Rebecca also conceived and leads the Google Earth Outreach program, which supports nonprofits, educators and indigenous communities in applying Google's mapping tools to the world's most pressing problems in environmental conservation, human rights and cultural preservation. Her personal work using Google Earth was instrumental in stopping the logging of more than a thousand acres of redwoods in her Santa Cruz Mountain community.  She received a bachelor’s degree in artificial intelligence with honors from Brown University and a master’s degree from Stanford University.  In 2013, Rebecca was recognized by the White House as a Champion of Change for Open Science.
