About

Guangyang Hong is a rising researcher in the physics of granular materials, with a focus on the complex dynamics of intruder motion and rheology in dense, vibrated systems. His work bridges fundamental soft-matter physics with applications in robotics, biomimetics, and geotechnical engineering. Hong’s major contributions include experimentally unveiling the mechanisms of self-propelled ascent in granular media—a phenomenon critical for understanding how animals and robots move through sand or soil. His 2025 study on this topic, already garnering 5 citations, demonstrates how a vibrating intruder can rise against gravity, challenging previous models of granular drag. He has also systematically explored the yielding transition in beam-vibrated granular systems, showing how frequency and amplitude control the transition from solid-like to fluid-like behavior, with implications for underground structural stability. Additionally, Hong’s work on multiscale memory effects reveals how granular materials retain a history of past vibrations, influencing their nonlinear response. With several high-impact papers published in 2024–2025, Hong is establishing himself as a key voice in granular physics, offering fresh experimental insights that connect microscopic grain interactions to macroscopic locomotion and rheology.
