The United Kingdom Health Security Agency (UKHSA) is a system leader for health security; taking action internationally to strengthen global health security, providing trusted advice to government and the public and reducing inequalities in the way different communities experience and are impacted by infectious disease, environmental hazards, and other threats to health.

UKHSA’s remit, as an agency with a global-to-local reach, is to protect the health of the nation from infectious diseases and other external threats to health. As the nation’s expert national health security agency UKHSA will:

Prevent: anticipate threats to health and help build the nation’s readiness, defences and health security
Detect: use cutting edge environmental and biological surveillance to proactively detect and monitor infectious diseases and threats to health
Analyse: use world-class science and data analytics to assess and continually monitor threats to health, identifying how best to control and mitigate the risks
Respond: take rapid, collaborative and effective actions nationally and locally to mitigate threats to health when they materialise
Lead: lead strong and sustainable global, national, regional and local partnerships designed to save lives, protect the nation from public health threats and reduce inequalities.

Detailed job description and main responsibilities

This role would typically be suitable for someone with a few years postgraduate experience or someone looking for a postdoctoral type role. As postholder you would, in conversation with your line-manager, be expected to lead research and development of the team’s work under the HPRU. Depending on the level of demand on the team you may supervise short-term placement students and interns or PhDs within the HPRU. You would bring mathematical / technical expertise to ensure that scientific and other outputs are produced in a timely way.

The team’s work-packages currently comprise:

• Source-term estimation – locating pathogen sources from case data.
• In-host dynamics – how a pathogen behaves inside the human body.
• Model frameworks – high level code for the rapid production of models.
• Neural networks for model emulation and machine vision – using the power of inferential tools to speed up models and to detect health threats.

The specific projects under the HPRU likely assigned to this role, either directly or in collaboration with others in the team, being:

• Applied records of traumatic events and mass injury surveillance

This aims to create a global database of non-fatal injuries, including sequelae (e.g. disease, deprivation) and probability of survival. Focussing especially on disadvantaged communities, we will explore the long-term burden of disease, psychosocial sequelae and socioeconomic hardship of survivors of a major incident.

• Syndromic surveillance of injury and correlates of community resilience

This project will look at the syndromic surveillance of injuries and observe how these may predict incoming demand on the health system and will: characterise the nature and seasonality of such reports, investigate linkable statistics to help drive causal inference, look into the differential of report types between different types of medical unit.

You would be expected to be knowledgeable in some mathematical, statistical, or computational techniques and be willing to learn others. Similarly, you will be able to show ability to progress projects and may contribute to developing the project portfolio within the team through grant applications and other funding opportunities.

You will be expected to be a role-model for the technical and behavioural aspects of the team. In the latter aspect, team skills are important to this role as is demonstrating a forward-looking and investigative nature.
You should be able to identify, discuss and act on your own professional performance and training / development needs and would be expected to attend virtual or physical internal and external training events. This would include all mandatory training (e.g. fire safety, information governance, etc.)

As postholder you will develop working relationships, communicate, and maintain vital interactions with collaborators in academia and across government and would comprise regular contact with a wide range of individuals, clinical and non-clinical, internal and external to UKHSA. This is expected to include: daily collaboration with the other members of the Modelling for EPRR team and individuals within the wider Advanced Analytics (AA) division (which includes Data-science, Economics, and Epidemiology Teams); regular contact with other members of the wider Analysis and Intelligence Assessment directorate and people within the HPRU at University of Birmingham, with the AA senior leadership team, directorate and HPRU administrative staff, and with HPC support staff; and periodic or occasional contact with other modelling, statistics and epidemiology teams within UKHSA, Dstl, DHSC, Cabinet Office and other similar organisations.
The above is only an outline of the tasks, responsibilities and outcomes required of the role. You will carry out any other duties as may reasonably be required by the agency.

Essential Criteria.

We will be assessing your demonstrated ability to think critically about the world and break problems down into pieces that are amenable to quantitative representation (mathematical or statistical modelling).

You should be expecting to show the panel examples of where you have done this previously and what the outcomes of your work was.

Higher degree (preferably PhD) or substantially equivalent experience in: the application of research focused computer code or mathematical modelling or statistics to problems in health (human, animal, or plant), microbiology or biological sciences.
Demonstrable practical postgraduate experience in applying one or more of the techniques in the core skills ( Mathematics, Statistical modelling, Modelling, Data analysis) below.
Well-developed skills in producing computer code from mathematics and/or algometric description (preferably Python, but any mainstream language acceptable)
Excellent communication skills written, verbal, tele/videoconferencing.
Able to work together with others to achieve goals (team player).
An understanding of and commitment to equality of opportunity and good working relationships, both in terms of day-to-day working practices, but also in relation to team management.

For posts on UKHSA Civil Service terms and conditions, new entrants to the Civil Service are expected to start on the minimum of the pay band. For existing Civil Servants and roles advertised across government, the rules of transfer apply, i.e., level transfers move on current salary or the pay range minimum, transfers on promotion move to new pay range minimum or receive a 10% increase. Either case is determined by whichever is the highest.

Future location

UKHSA is investing in a new state-of-the-art National Biosecurity Centre in Harlow, Essex, which will eventually bring together teams currently based at Canary Wharf, Colindale and Porton Down. For more details, please see: Huge biosecurity centre investment to boost pandemic protection - GOV.UK.

The new facilities will start becoming operational in the mid-2030s, with full completion by 2038. Staff will move in phases as facilities become available. If you're appointed to a role currently based at Canary Wharf, Colindale or Porton Down, please note that we'll continue investing in these sites for the next decade.
