I am an assistant professor in the Computer Science Department at Virginia Tech. I received my Ph.D. in Computer Science at the University of California, Los Angeles, where I was advised by Miryung Kim. I am the recipient of Google Ph.D. Fellowship 2017-20.

The vision of my research is to build systems that improve developer productivity through automated debugging and testing for big data analytics. Broadly, I am interested in designing novel tool support for data-centric software development. My approach combines insights from software engineering, distributed systems, and databases. My past work has focused on interactive and automated debugging for Apache Spark, symbolic execution based test generation for dataflow programs, and performance debugging in Apache Spark.
