I am a tenure-track assistant professor in the Department of Mathematics at University of Wisconsin – Madison, and also a member of the Institute for Foundations of Data Science.
I work in the fields of probability, combinatorics, dynamical systems, optimization, and machine learning.
My research is broadly driven by questions related to understanding emergent or latent properties of complex systems and data sets. Such questions and techniques that I develop to address them span across the fields of probability, combinatorics, dynamical systems, optimization, and machine learning.
I am the principal investigator of the NSF Grant DMS-2010035 on Combinatorial and Probabilistic Approaches to Oscillator and Clock Synchronization.
I am looking for self-motivated Ph.D students starting from Fall 2021. Please send me your CV to hlyu@math dot wisc dot edu.
Before joining UW-Madison, I was a Hedrick Assistant Professor at UCLA department of mathematics.
I earned a Ph.D in mathematics at the Ohio State University in 2018. My thesis is on “Combinatorial and probabilistic aspects of coupled oscillators“. David Sivakoff was my thesis advisor. (Slides for my dissertation talk: thesis_talk)
I earned my B.S. in mathematics at Seoul National University in South Korea.
