I’m Yung-Chang Hsu.

Current affiliation

I’m doing my Ph.D. in mathematics under the supervision of Professor Victor Lie at Purdue University.

Personal interest

I started as a math and music enthusiast. To me, understanding the time-frequency phase portrait of a mathematical object has the same connotation as analyzing the score of a musical composition.

This realization led me to choose the path of time-frequency/wave-packet analysis, a subfield of harmonic analysis, to start my academic career.

I’m also interested in any other related fields of study. (e.g. P.D.E., geometric measure theory, ergodic theory, or even machine learning.)
