Dr. Huihui Hong is an Assistant Research Fellow and Postdoctoral Fellow at the School of Medicine, Chongqing University, whose research spans environmental toxicology, occupational health, and molecular mechanisms underlying pollutant-induced diseases. With academic training that includes a doctoral degree in Occupational and Environmental Health from Zhejiang University and a bachelor’s degree in Preventive Medicine from Hangzhou Normal University, she has built a strong foundation in toxicological mechanisms, environmental exposure assessment, and cellular pathology. Dr. Hong’s research focuses on the biological consequences of exposure to heavy metals and environmental pollutants, such as cadmium, manganese, paraquat, and dissolved organic matter, and she explores how these toxicants interfere with metabolic regulation, β-cell function, lipid homeostasis, mitochondrial integrity, neuronal signaling, and inflammatory responses. Her work has revealed critical mechanistic insights, including pollutant-induced ferroptosis through axes such as Gpx4/Ager/p65, mitochondrial dysfunction-dependent β-cell impairment, lipidomic disturbances contributing to diabetes progression, and neuroinflammatory pathways leading to Parkinson-like phenotypes. She has also contributed to understanding the molecular impact of chlorination disinfection on dissolved organic matter in surface water sources and how such transformations influence cytotoxicity, advancing environmental health risk assessment. Dr. Hong has authored more than twenty scientific publications, many as first author or corresponding author, in prominent international journals covering environmental science, toxicology, and public health. According to current bibliometric sources, her scholarly output has accumulated approximately 466 citations, and based on citation distribution, her estimated h-index is in the mid-teens, demonstrating strong research visibility and influence at an early stage in her career. In addition to elucidating pollutant-driven metabolic and neurological injury, she frequently collaborates across multidisciplinary teams to integrate metabolomics, lipidomics, molecular biology, and in vivo toxicology, strengthening the translational relevance of her findings. Through this combination of methodological rigor, mechanistic depth, and sustained productivity, Dr. Hong continues to expand her impact within environmental toxicology, contributing valuable knowledge toward understanding how environmental exposures shape human health risks and guiding future intervention or prevention strategies within public health and environmental safety domains.
