About

My name is Liang Chen. I am commonly referred to as Jeff in my professional career. I am a member of Cloud & Mobile Research Group. I obtained BS and MS from Tsinghua University, and PhD from UC San Diego.

I am generally interested in data management. While initially working on text search and ranking in my graduate studies, I gradually developed interests in building data management systems. Over the last couple of years, I’ve been pursuing these interests through understanding the links between SQL and NoSQL database systems, bridging the gap between them and transforming today’s data platforms to new products and services. This line of work has taken me to a fantastic journey, luring me into cloud computing and yielding promising systems and unanticipated business impact:

  • GraphView is a middleware on existing data platforms that presents to applications a view of a graph database, while internally maps graphs to native data structures of the underlying system and compiles graph programs into data instructions executed by it. Initially released as an open source project, GraphView not only inspired SQL Graph in SQL Server 2017, but later became the backbone of Azure Cosmos DB Graph, a globally-distributed graph database as a service.
  • JSON Server is a middleware that transforms a SQL database to a JSON database, with superior performance and functionality.
  • More previously, I was the co-inventor of XML sparse mapping, which was released in SQL Server as Selective XML Index (SXI).

I am looking for interns who are interested in taking the wave of cloud computing and building the next generation of database services. Drop me a message if you are intrigued. My address: jeche followed by AT and microsoft.com.
