Welcome

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

About me

I’m currently a final 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 (and Puerto Rico) in the U.S. and 12 countries in the world. I’ve spent 1,111.2 hours just in the air and travelled 674,063 kilometers by plane, that is 16.8x around Earth or 1.75x to the moon!
