Welcome to my personal website!

I am currently a sixth-year Ph.D. candidate at the Information Systems Group (ISG), Computer Science department, University of California, Irvine. I am advised by Dr. Chen Li and expect to graduate in July 2025. I received my B.S. in Computer Science from University of California, Irvine as well.

My research focuses on big data management, data-processing systems, and machine learning systems. I take a systems-driven approach by co-designing the key components of modern data-intensive pipelines, including workflow engines, UDF debugging frameworks, pipelining optimizers, and machine learning acceleration systems for streaming data. To optimize performance, usability, and scalability, I integrate techniques across data management, distributed systems, program analysis, and machine learning.

I have contributed extensively to the Texera project (Apache Incubating), a collaborative and interactive system for data science and AI/ML using workflows. My research has been published in database venues such as SIGMOD (Udon, Pasta, etc) and VLDB (Texera, IcedTea, CORE, etc), and my interdisciplinary work spans venues including TOCHI, PNAS Nexus, JAMIA, AMIA, and PLOS ONE.

My research was recognized with a SIGMOD 2024 Best Demo Runner-Up Award and has been supported by fellowships including the 2025 Joseph & Dorothy Fischer Memorial Endowed Fellowship, the 2025 Beall Family Foundation Graduate Student Entrepreneur Award in Computer Science, the 2024 Graduate Dean’s Dissertation Fellowship, and the 2023 Public Impact Fellowship.

My expertise has been further shaped through internships at Observe, ByteDance, VISA and Observe. I have also led collaborative research projects and mentored over 50 students across various levels.

Updates:

  • 🚀 Thrilled to share that I’ll be joining Databricks in 2025, working on the Apache Spark Runtime team to advance one of the fastest and most scalable data engines in the world!
  • 🎓 Looking ahead, in Fall 2027, I’ll transition to the Manning College of Information and Computer Sciences (CICS) at UMass Amherst as a Tenure-Track Assistant Professor!
