I am a Ph.D candidate in mathematics at the Ohio State University, expected on May 2018.

I will join UCLA as a Hedrick Assistant Professor this year 2018-2019.

I earned my BS. in mathematics at Seoul National University in South Korea.

I work in the fields of probability, combinatorics, dynamical systems, and distributed algorithms.

I am interested in understanding emergent behavior of complex dynamical systems through concrete mathematical models and finding algorithmic applications. I am also branching into developing new methods for network data analysis.

Topics studied: Persistence of Markov additive functionals, firefly cellular automata (on finite trees and Z), 3-color cyclic cellular automata and Greenberg-Hastings model (on general graphs), pulse-coupled oscillators (on trees), clock synchronization algorithm (on general graphs), box-ball system (on Z), parking process (on transitive unimodular graphs), 3-color cyclic particle system (on Z), Euler characteristic and 3-connected graphs, and stable operations on graphons (for network data analysis).

Here is my CV_lyu. Check out my research_statement_Lyu and teaching_statement_Lyu.

My thesis advisor is David Sivakoff.

My collaborators are Janko Gravner, Lionel Levine, John Pike, Facundo Memoli, Matthew Junge, Eric Foxall, and Michael Damron.
