Biography

Ion Stoica is a Professor in the EECS Department at the University of California at Berkeley, where he holds the Xu Bao Chancellor's Chair and is the Director of SkyLab (https://sky.cs.berkeley.edu/). He is currently doing research on cloud computing and AI systems. Past work includes Ray, Apache Spark, Apache Mesos, Tachyon, Chord DHT, and Dynamic Packet State (DPS). He is an Honorary Member of the Romanian Academy, an ACM Fellow and has received numerous awards, including the Mark Weiser Award (2019), SIGOPS Hall of Fame Award (2015), and several "Test of Time" awards. He also co-founded three companies, Anyscale (2019), Databricks (2013) and Conviva (2006).
