Introduction
I am specialised in the One and Planetary Health cross field of biological effects from exposure to environmental chemicals, diseases and climate change. I am working with a broad range of animals including predatory mammals, raptorial birds, sea birds, fish and Humans focusing on immunity, and endocrine disruption. I have a great interest in the Global Goals and sustainability, zoonoses, pollution, energy, recycling, remediation, biodiversity and ecosystem services.

Article
Antibiotic residues have become a global environmental concern, as these emerging contaminants are frequently detected in water bodies at concentrations exceeding ecotoxicity thresholds, posing risks to aquatic ecosystems and water quality. This study extensively evaluated the efficacy of glutamic acid-modified graphene oxide (GO@Glu) nanocomposite...
Article
Tetracyclines are broad-spectrum antibiotics used as human and veterinary ailments, anticancer and antiviral agents, and for treating inflammations including arthritis and the Huntington’s disease. However, their inappropriate usage and disposal induce environmental pollution due to their persistency, hydrophilicity and limited volatility, requirin...

Interest in virtual fencing has increased due to its flexibility for agriculture and rewilding. However, systems like Nofence© require large financial investments, and the need for individual collars complicates large-scale use. If cattle herds maintain cohesive groups around leading individuals, fewer collars could be used, thereby enhancing cost...
Article
Crop pest invasions and their interactions with climate change may have been overlooked in crop yield projections, hindering the development of climate-resilient and sustainable agriculture. A harmonized strategy is proposed to integrate such interactions into crop yield projections and management under climate change scenarios.

Epigenetic regulation plays an important role in the evolution of species adaptations, yet little information is available on the epigenetic mechanisms underlying the adaptive evolution of bamboo‐eating in both giant pandas (Ailuropoda melanoleuca) and red pandas (Ailurus fulgens). To investigate the potential contribution of epigenetic to the adap...
Article
Compared to other organic contaminants, birds are rarely studied for their exposure to polycyclic aromatic hydrocarbons (PAHs), mainly due to their effective metabolization of parent PAHs. However, as some studies suggest, exposure to PAHs may result in adverse health effects including decreased survival, especially following oil spills. In the pre...

Contamination of rice by the potent neurotoxin methylmercury (MeHg) originates from microbe-mediated Hg methylation in soils. However, the high diversity of Hg methylating microorganisms in soils hinders the prediction of MeHg formation and challenges the mitigation of MeHg bioaccumulation via regulating soil microbiomes. Here we explored the roles...

Article
Over 100 million tons of cotton waste are produced annually, representing 35-40% of global textile waste. However, less than 30% of cotton waste is recycled annually. In particular, the fibers less than 7 mm in length dropped during the opening and carding process of cotton waste fabrics have not found a mature utilization method. This work demonst...

Phthalate esters (PAEs) are known as esters of phthalic acid, which are commonly used as plasticizers in the plastic industry. Due to the lack of chemical bonding with the polymer matrix, these compounds are easily separated from plastic products and enter the environment. To investigate the growth of concentration of PAEs like DBP (Dibutyl phthala...
