I work at the interface between systems and ML, and lead the Facebook AI Infrastructure Foundation, which focuses on efficient and scalable hardware and software platforms for Facebook’s production and mobile use cases of machine learning. My research interests include workload characterization, performance analysis, computer systems architectures and scalable datacenter systems. Prior to Facebook, I held positions including a tenured Associate Professor at the University of Virginia, Software Engineer at Google, and Director of Systems Research at Yahoo Labs. I received a PhD in computer science from Harvard University in 2004, and am the recipient of an NSF CAREER Award, the Anita Borg Early Career Award, the MIT Technology Review Top 35 Innovators under 35 Award and the ACM SIGPLAN 10-Year Test of Time Award. I have authored over 50 conference papers and one book.
