Junchen Jiang

Welcome! I joined the Dept. of Computer Science at The University of Chicago as an Assistant Professor in July 2018.

I got my PhD degree from Computer Science Department at Carnegie Mellon University in 2017. I was advised by Vyas Sekar and Hui Zhang. Before that, I received Bachelor degree in Computer Science from Yao Class at Tsinghua in 2011.

Research interests: networked systems. My research applies state-of-the-art machine learning techniques to drastically improve the performance and reliability of large-scale networked systems.

[Curriculum Vitae]

I'm looking for self-motivated students to work with me at UChicago. Please apply here and mention my name in the application. Feel free to drop me an email with your CV.

Feel free to contact me too, if you are interested in internship opportunities in my group.
