I am a Professor of Computer Science Division at University of California, Berkeley, and
currently the Director of Sky Computing Lab. I am also a co-founder of Anyscale (2019), Databricks (2013), and Conviva Networks (2006). Here is a short bio.

Research
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:
- Alpa,
an automatic model-parallel training and serving system for large-scale
neural networks.
- 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 iterative computations.
- 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 per-flow state.
- Hierarchical Fair
Service Curve (HFSC), an hierarchical
scheduling algorithm that decouples the bandwidth and delay allocations.
