Fascinating graph shows the estimated total mass of all the mammals living on Earth. In 1850, it was evenly divided between wildlife and humans + domesticated animals. Today, humans and their livestock account for about 95% of the total. 🧪 www.nature.com/articles/s41...
Black labels indicate absolute biomass estimates, gray labels indicate the fraction of the total estimated biomass of mammals (see Fig. S9 for the estimated fraction of global biomass). Top: the total biomass of humans and domesticated mammals (cattle, buffalo, swine and others). Bottom: the total biomass of wild marine mammals, along with a coarse, preliminary estimate of the total biomass of wild land mammals, based on previously published temporal abundance estimates.

📣 Funded 3.5yr PhD opportunity for UK applicants in @hpruezi.bsky.social @liverpooluni.bsky.social. #PhDSky 🧪 On "Optimising testing & control strategies in the early stages of infectious disease outbreaks" #IDSky #EpiSky ⏳ Application deadline: 24 Mar 2025 🔗: www.liverpool.ac.uk/study/postgr...
Optimising testing and control strategies in the early stages of infectious disease outbreaks

Supervisors: Dr Emily Nixon   Professor Christl Donnelly   Dr Richard Vipond   Dr Emily Adams 

Research area:
Maths and Computing

Studying in:
Department of Mathematical Sciences School of Physical Sciences Faculty of Science and Engineering

Stipend Amount: Funded studentship
Availability Region: Open to UK applicants
Application Deadline: 24 March 2025In the early stages of a major disease outbreak, the availability of suitable diagnostic tests is often limited, however, timely interventions are critical for controlling the spread of disease. In this PhD, you will develop mechanistic and statistical models to investigate the effectiveness of various diagnostic test deployment strategies for emerging and zoonotic diseases which are at risk of causing large outbreaks, such as respiratory viruses (Influenza, SARS-CoV-2, Respiratory syncytial virus), vector-borne diseases (Dengue, Tick-borne encephalitis) or viral haemorrhagic fevers (Nipah, Lassa fever and Crimean-Congo haemorrhagic fever). You will investigate the effectiveness of targeting use of tests in different settings, for example in areas of high versus low transmission, or in hospitals versus the community. The optimum strategy for diagnostic test deployment will vary depending on prevalence of disease, the sensitivity and specificity of the tests and the time it takes to receive and act on results. In addition, variation between pathogens, for example, in their mode of transmission, reproduction number and incubation period, will influence which strategy is the most effective in controlling the impact of the outbreak. These insights will inform stockpiling strategies of medical countermeasures for pandemic preparedness and in the event of a major outbreak, can be used and adapted to help inform decision making.You will be part of a supportive and stimulating research environment at the University of Liverpool, with Dr Emily Nixon as your primary supervisor, with additional supervision from Professor Christl Donnelly (Department of Statistics, University of Oxford), Dr Emily Adams (Pandemic Sciences Institute, University of Oxford) and Dr Richard Vipond (UK Health Security Agency). This studentship will be for a maximum of 3.5 years duration starting in October 2025; it includes fees at the UK/home rate, stipend, and research-related travel.This is an exciting opportunity to work with a world leading team delivering research that is relevant to public health in the UK. This PhD opportunity is funded by the National Institute for Health and Social Care Research (NIHR) Health Protection Research Unit (HPRU) in Emerging and Zoonotic Infections (EZI). The successful candidate will therefore join the NIHR HPRU-EZI.

NIHR is the UK's largest funder of health and care research and provides the people, facilities and technology that enables research to thrive.

NIHR HPRUs undertake high quality research that enhances the ability of the UK Health Security Agency (UKHSA) to protect the public’s health and minimise the health impact of emergencies. There are 13 HPRUs across England.

The HPRU-EZI is a partnership between the University of Liverpool, Liverpool School of Tropical Medicine (LSTM), University of Oxford, London School of Hygiene & Tropical Medicine and UKHSA, in collaboration with University of Glasgow. HPRU-EZI has been running since 2014, and supports and strengthens UKHSA in its role protecting England from emerging infections and zoonoses (i.e. those which spread from animals to humans). HPRU-EZI has played significant roles in the past in the UK response to Ebola, Zika, COVID-19 and mpox. We will continue to address the major emerging threats; these are transmitted by mosquitoes and ticks (e.g. dengue and Lyme), the respiratory route (e.g. COVID-19 and influenza), or directly through contact (e.g. Lassa fever).
