I am a Professor of
Computer Science Division at University of California,
Berkeley, and currently I am leading RISELab. I am also a co-founder of Databricks, and a co-founder of Conviva Networks. Here is a short bio.

My area of research is cloud computing, distributed systems, and
networking. I am equally interested in designing algorithms and
systems with strong theoretical foundations, and in providing
practical implementations that are deployable in the real world.
A list of my
publications are available here.
- Some current projects include:
- Ray, a low-latency distributed execution framework for machine learning and reinforcement learning applications.
- Clipper, a low-latency, high-throughput prediction and model serving system.
- Succinct, an
efficient storage system that supports sub-string queries on compressed data.
- Apache Spark, a
cluster computing frameworks to efficiently support interactive, and
- Some previous projects:
- Apache Mesos, a cluster manager
that provides efficient resource isolation and sharing across
cluster computing frameworks, such as Hadoop, MPI and Hypertable.
- Alluxio (formerly known as Tachyon), a
an in-memory distributed storage for big data processing.
- OCALA, an overlay architecture for deploying legacy applications over new Internet architecture.
- Internet Indirection Infrastructure (i3), an network architecture that uses a rendezvous-based communication abstraction to support a wide variety of communication abstractions, including multicast, anycast and mobility.
- Chord, and efficient lookup protocol for peer-to-peer networks.
- Older projects (during my graduate studies, at CMU):
- Dynamic Packet State (DPS), a scalable QoS
and resource management architecture for the Internet. The main idea
of DPS is to have packets carry per-flow state, instead of
maintaining the state at routers. One instantiation of DPS is CSFQ (Core-Stateless Fair Queueing), a protocol
that provides fair sharing without requiring routers to maintain any
Fair Service Curve (HFSC), an hierarchical scheduling algorithm
that decouples the bandwidth and delay allocations.
