Welcome

Curious about how to write my Chinese name? It’s simply 吴仁杰.

About me

I’m currently a 5^th year Ph.D student with the Department of Computer Science and Engineering at University of California, Riverside. My advisor is brilliant Dr. Eamonn Keogh. My research interest includes time series analysis, data mining, and machine learning.

I like travel, especially by rail and air. I’ve visited all 50 states in the U.S. and 11 countries in the world. I’ve spent 874.1 hours just in the air and travelled 557,201 kilometers by plane, that is 13.9x around Earth or 1.45x to the moon!
