Dr Xiaocheng (Sam) Hu joined the ECEHH in January 2019. At ECEHH, in collaboration with a local SME, Sam works on the Innovate UK project and applies his analytical skills to understand the contribution of volatile anaesthetics to global warming. In 2020, he had also involved in a short-term project (September – December) looking at the economic and environmental impacts of COVID-19 on plastic use in NHS hospitals. He is now based in the Environment and Sustainability Institute working on a project to evaluate the plastic consumption behaviour of UK households. 

Sam holds a PhD in Economics from the University of Southampton, United Kingdom. His primary research interests lie in personnel economics and experimental economics, with a particular focus on the economic and social impacts of teamwork and incentive schemes.

Sam also has a deep interest in inequality. In 2018, he was involved in a project at the Southern Policy Centre (part-time) on whether different patterns of material inequality at the household level mirror in individual outcomes across the life course such as health and education.

Applied econometrics, personnel economics, experimental economics, and environmental economics (in the context of healthcare). 

Research projects

COVID and Waste

Single-use personal protective equipment (PPE) is critical to protect healthcare workers during the COVID-19 pandemic. However, this may neutralise the previous effort made by the NHS Trusts to reduce their plastic footprint. In collaboration with the local Trust - Royal Cornwall Hospitals, Dr Sam Hu, Prof Lora Fleming, Prof Karyn Morrissey, Prof Richard Smith, and Prof Peter Hopkinson investigated the effect of COVID-19 on the effort of reducing single-use plastic at the hospital.

Sustainable Inhalational Anaesthetic Gases

The NHS spends about 50 to 60 million pounds on inhalational anaesthetic gases per year. However, approximately 98% of these gases are vented to the atmosphere. The global warming potential, for example desflurane is 2,540 times more likely to cause global warming than carbon dioxide. In collaboration with a leading tech start-up SageTech Medical, as part of the Industrial Strategy Challenge Fund (ISCF) project, Dr Sam Hu, Dr Tim Taylor, and Prof Karyn Morrissey estimated the economic and environmental impacts of a new vapour capture technology.
