His research focuses on computer architecture, programming languages and OS to improve the programmability, reliability and energy efficiency of multiprocessor systems. He has co-authored over 60 papers in these areas, and had several papers selected as IEEE Micro Top Picks and CACM research Highlights. He participated in the Blue Gene, Cyclops, and PERCS projects at IBM Research and received IBM awards. He is also a recipient of an NSF CAREER Award, a Sloan Research Fellowship, a Microsoft Research Faculty Fellowship and 2013 IEEE TCCCA Young Computer Architect Award. He consults for Microsoft Research and co-founded Corensic and Konyac, both UW-CSE spin-off companies. He was born and raised in Sao Paulo, Brazil, where it drizzles all the time; he now (mostly) lives in the similarly drizzly Seattle. When he is not working he is found either eating or cooking.
