Graduate Mathematical Modeller - CBR

Within the Chemical, Biological and Radiological Division our mission is to support the MOD and Other Government Departments to ensure intelligent decision-making is at the heart of the UK government thinking. We work in partnership with the best suppliers from industry, academia and international allies to deliver creative cost effective S&T solutions that reduce the risk CBR materials pose to the UK.

The Modelling and Analysis Team provide Chemical and Biological hazard assessment advice, primarily through the use of models, to support operations, advice, policy and research for enclosed and complex environments including buildings, transport infrastructure and military platforms.

The team works on a dynamic range of projects, contributing to a team of specialists delivering critical scientific, analytical and technical advice. We develop and use novel analytical models and techniques and will undertake ground-breaking research and experimentation at the forefront of defence and security research, which is a dynamic and rapidly evolving environment. Quite simply, we believe this is work you cannot do anywhere else.

This role will sit in a team with approximately 8 other mathematical modellers and analysts. The team have a very wide portfolio of projects which range in value from £10k through to £1M and most team members work on at least 2-3 different projects to ensure the development of knowledge and skills in a broad range of topics. Each project will draw staff from not only within the team but others across the group or Division and so it is expected the role will have an element of networking across the lab. Collaborative work with MOD, OGD, UK industry and international partners.

We will support your early career development through a mixture of on-the-job, course-based training which include;
• A wide range of interesting training modules for you choose from to build your technical ability and military, defence and security domain awareness.
• Talks and discussion groups led by some of our technical experts.
• Personal skills development.
• Networking with other new starters, both in our division and across Dstl, including access to our new starter support network.

Job description

In this role you will:
• Work with others to deliver to projects within the team by using logical thinking and problem solving skills to solve difficult technical problems and presenting these to technical leaders in the most appropriate format (discussions, spreadsheets, databases, reports, email).

• Provide a scientific contribution to customer deliverables in the form of reports and presentations.
• Support the objectives of the team by contributing to team meetings and wider activities across Dstl.
• Provide senior technical leaders with support in maintaining, developing and using the group’s models.
• Build up expert knowledge in a number of technical areas and network both within your capability area and across capability boundaries.
• Communicate complex mathematical modelling ideas to various audiences.


We are looking for someone who has:
• The ability to take responsibility for their own work and plan their work to meet project timeframes.
• The desire to apply their technical understanding to solve problems which are unfamiliar to them.
• Strong communication and interpersonal skills.

A post graduate qualification in the subjects listed above.

• A strong attention to detail.
• Excellent communication skills.
• A dedication to learning new skills and working within a multi-disciplinary team.
• Able to organise workload.
• Agility to respond to changing demands.
• Aptitude for building relationships
• Using knowledge, experiences and networks to solve complex problems.

• Experience of scripting using Python (or similar)
• Understanding of fluid dynamics

• Experience of Mathematical modelling.
• Experience of working as part of a team and independently, as you will be required to undertake analysis independently and still work effectively in a scientific team.
• Experience in using Microsoft Office package (Excel, Word, PowerPoint, Outlook) for data analysis, technical reports and presentations.

• Having some knowledge of the UK armed forces
• Experience of using computational fluid dynamics software
• Experience of multizone indoor air or building energy modelling
• Experience of building and other enclosed space ventilation.
