H. Guan's earlier publications (2016-2023) focus on precision atomic physics, particularly trapped single ions such as calcium-40 and ytterbium-174, used to build ultra-precise optical atomic clocks and measure atomic properties like energy-level lifetimes and transition strengths. More recent publications (2024-2025) shift toward applying machine learning methods, including graph-based generative adversarial networks and transformer models, to brain connectivity mapping and medical prediction tasks. Note that the bibliographic record may combine work from more than one researcher sharing this name, given the disparate subject areas.
Publication output was sparse and irregular from 2017-2022 but has grown sharply since 2023, with a notable surge in 2024-2025.
