about me

I recently obtained PhD of Electrical and Computer Engineering from the University of Illinois Urbana-Champaign and joined Apple. I was advised by Sanmi Koyejo and a member of Stanford Trustworthy AI Research Lab. My PhD thesis focuses on estimations and predictions in dynamical systems where data are collected in non-i.i.d. fashion. Specifically, I (i) developed efficient methods to estimate graphs from continuous time-series with guarantees and (ii) used the graphs to address distribution shifts problems. You can find my thesis here. My PhD research was supported by NSF Graduate Research Fellowship.

Previously, I completed my undergraduate degree at National Taiwan University and master degree at University of Illinois Urbana-Champaign, both in Electrical Engineering. During my graduate studies, I interned at Google Brain and Intel AI lab.
