Biography

I am a Ph.D. student at NUS and Alibaba DAMO Academy, advised by Asst. Prof. Yang You and Dr. Kai Zeng. I received my B.Eng. in Computer Science from Nanyang Technological University, where I was fortunate to work with Prof. Bo An and Prof. Chen Change Loy.

I like designing algorithms for system, and I want to build highly efficient systems. I was a Machine Learnning intern with Turi team of Apple, supervised by Jay Gu and Pulkit Agrawal. Besides, I have worked with MMLab@NTU, SenseTime, nuTonomy(now a part of Aptiv), and TUMCREATE.

I have spent four wonderful years with NTU HPC club. We won an Overall Championship at SC'17 and set LINPACK World Record. Our team has also won 1st Runner Up at ISC'18.

Understanding C++ Performance (1) : Stack and Heap
One thing about C++ that attracts me a lot is that it gives me control over the program to a great extent. Therefore, I am starting an article series on why C++ is efficient from the implementation perspective.

Diving Deep into Data Alignment
Recently I came across an interesting topic on memory access optimization named data alignment. I know that struct can be seen as public class, and the performance of struct of array is better than array of struct thanks to contiguous memory.
