Assistant Professor


Department of Computer Science and Engineering


University of California, Riverside



Office: Winston Chung Hall 335




I'm teaching CS 141: Intermediate Data Structures and Algorithms in Fall 2020.


I am an Assistant Professor at the University of California, Riverside (UCR) from Jan. 2020. I'm looking for self-motivated Ph.D. students. If you are interested, please contact me via email and attach your CV.



I was a postdoc associate at MIT CSAIL in 2019, working with Julian Shun. Before that, I finished my PhD also at Carnegie Mellon University, advised by Guy Blelloch. Prior to that, I received my Bachelor degree in Computer Science at Tsinghua University in 2012. My personal webpages are also available on [dblp] and [Google Scholar]. You can find my [CV] here.




My current research interest is design efficient (usually parallel) algorithms for large-scale data with good performance in practice.

Ph.D. Thesis

Selected Publications


Papers on this page are categorized in different topics. Paper list in reverse chronological order can be found here.


Algorithm papers


Algorithms for New Architecture


These papers tried to understand and develop efficient algorithms for the upcoming non-volatile main-memory (NVM). This includes modified computational models, new algorithms, new techniques to support efficient computation, etc.


Parallel Algorithms


These papers developed efficient parallel algorithms for fundamental problems or parallel primitives (e.g. sorting, shortest-paths, convex hull, Delauney triangulation, SCC, random permutation, list/tree contraction). All of these new algorithms are highly practical, and with better or matching bounds comparing to previous theoretical approaches.

Miscellaneous Topics


This is a random sample of topics that I occasionally looked into. They are standard sequential algorithms with the goal to minimize the time complexity.


Graphics papers


I spent most of my time from 2010 to 2014 on computer graphics research (most of the algorithm papers are done starting from 2015).


BVH Construction


These papers discussed some interesting algorithmic improvements either to accelerate the construction or to improve the quality of the bounding volume hierarchy, which is one of the most commonly-used data structure in computer graphics. All these papers improved the state-of-the-art (or at publish time) techniques much.

Miscellaneous Topics


This is another random sample of the topics I worked on during my undergrad and guaduate time, including works on geometry modeling and processing, image processing, and architectual and compiling considerations on GPU rendering.
