Biography

I am Qiaolin Yu, a graduate student at Cornell University and Cornell Tech. My interests primarily focus on machine learning infrastructure, database systems, and storage systems. Currently, I work as a research intern at Cornell Computer Systems Laboratory, advised by Udit Gupta. I also work closely with Zhichao Cao. I have three papers that are under revision, where I serve as the first author for one paper, co-first author for another paper, and third author for the third paper.

In conjunction with my academic endeavors, I have amassed significant industrial experience through a series of internships. I will join Databricks as a software engineer intern in 2024 summer. Previously, I have interned in the compute architecture team at PingCAP, the Azure Machine Learning team at Microsoft, the ByteHouse team at ByteDance, and the graph database team at Kuaishou.
