I 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 will teach CS260 in Spring 2020 on Algorithm Engineering (aka. How to Write Fast Code).

 

 

 

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. My personal webpages are also available on [dblp] and [Google Scholar]. You can find my [CV] here.

 

Prior to coming to CMU, I received my Bachelor degree in Computer Science at Tsinghua University in 2012.

 

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.
