Hi. I'm Juncheng Yang.

I am a master student in computer science at Emory University (CocaCola University :)) and I work under the guidance of Ymir Vigfusson on smart cache. Before this, I obtained my bachelor degree from Nanjing University.

Learn about what I do

Born in China, Live @ Atlanta. Here's all the stuff I do.

Computer Science, Chemistry and Photography.

Computer Science

I have very strong enthusiasm in computer science. My interests include computer system, information retrieval and web crawlers. And my current research focus is on cache replacement policies and building smart cache.


I like to travel and take photos, sometimes I make post cards for places I visit. I have been to China, US, Iceland, Japan, Germany, Switzerland.

Check Here for some good photos.


I took Chemistry as my major as undergraduate, which gives me the chance to better understand my life and connect chemistry with computer science.

Here’s some work I have been focused on recently.

I am focusing on computer science and all my researches and projects relate to it.

I have several hobbies, except talking :( but I am improving :).

Programming, Photography, Traveling, Eating and Cooking, Badminton, Playing Cards.


Programming is fun, especially when you use it to try out new ideas.

Photography and Traveling

I like beautiful photos, when I was young, I gathered good photos from others, but now I produce by myself.

This is one of my best sports. I was a member of the department team during undergraduate.

Eating and Cooking

Eating is one of the most important things in everyday life, no one can escape it, so why not enjoy it like me? Maybe inheriting from my chemical skills, I am also very interested in cooking.

Playing Cards

When getting together with friends, one of our favorite activities is playing cards, military chess and other kinds of board games.

Next? Flying!

Learning to fly a jet has always been one of my dreams, so that's my next target.
