I’m an associate professor at UC Berkeley (previously Stanford), where I work on computer systems and AI in the Sky Lab. I’m also co-founder and CTO of Databricks.

**Interests:** I’m interested in computer systems for large-scale workloads such as AI, data analytics and cloud computing.
In 2016, I co-started the Stanford DAWN lab to work on infrastructure for usable machine learning.
My recent projects include programming models for LLM applications, efficient runtimes for ML and analytics, quality assurance tools and AI-based data analytics systems.
I am also interested in data privacy, and have worked on systems that can provide scalable privacy for communication, Internet queries and SaaS applications.

**Open Source:** Most of my research work is open source.
During my PhD, I started the Apache Spark project,
which is now one of the most widely used frameworks for distributed data processing, and co-started other
datacenter software such as Apache Mesos and Spark Streaming.
At Stanford, we developed DAWNBench, a machine learning performance competition
that drew submissions from the top industry groups and influenced the industry-standard MLPerf,
and we are developing a wide range of open source software including
Weld, NoScope,
FlexFlow, ColBERT and DSPy.
I was also involved in Databricks’ work to release open source LLMs like DBRX and Dolly.

Some of my group’s past work has been featured in Wired (1/2/3), Fortune, TechCrunch, The Wall Street Journal, The Register, Ars Technica, Motherboard, ZDNet, The Economist, and Forbes.
