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 in the U.S. and 11 countries in the world. I’ve spent 995.8 hours just in the air and travelled 615,507 kilometers by plane, that is 15.4x around Earth or 1.6x to the moon!
