I’m an assistant professor at Stanford CS, where I work on computer systems and big data. I’m also co-founder and Chief Technologist of Databricks, the big data company commercializing Apache Spark. Prior to joining Stanford, I was an assistant professor of computer science at MIT.
I work on computer systems and large-scale data processing. My past projects included widely used datacenter software such as Spark, Mesos, Spark Streaming and Spark SQL, and cluster scheduling algorithms such as DRF, delay scheduling and LATE. My current projects include:
Weld, a runtime for data analytics applications that changes the interface between software libraries to enable powerful cross-library optimizations. Weld can increase the performance of widely used libraries such as Pandas, NumPy, TensorFlow and Spark by up to 30x, as well as make it much simpler to port parallel software across hardware platforms. (paper, code).
DAWN, a new Stanford lab to create infrastructure for usable machine learning. We observe that ML algorithms are now “good enough” for many applications, but the bottlenecks to real-world use are tasks around the algorithm, such as data labeling, data augmentation, and robust serving. We are developing runtimes, algorithms and serving systems to tackle these problems.
Scalable Strong Privacy systems that protect user data in common Internet applications at the scale of millions of users. For example, Vuvuzela is the first linearly-scaling messaging system that hides metadata about which pairs of users are communicating, while Splinter hides user queries on non-sensitive data (e.g., map routing on OpenStreetMap) from the service providers.

Almost all of my work is open source:
- The Spark engine is now an Apache project at spark.apache.org. We have also open sourced subsequent projects including Shark, Spark SQL, MLlib, GraphFrames and Spark Streaming.
- The Mesos cluster manager is a top-level Apache project.
- The LATE algorithm for straggler mitigation and the Hadoop Fair Scheduler are included in Apache Hadoop.
- The SNAP sequence aligner is available on GitHub.
I’m also a committer on the Apache Hadoop, Spark and Mesos projects.
