Professor Penelope Endersby, Chief Executive

It is my privilege to lead this successful and highly respected organisation, working at the forefront of weather and climate science, technology and operations. We constantly strive to harness the Met Office's world class capabilities for greater societal benefit.

I gained my first experience of scientific research as a sixth form WISE Scholar at GEC before completing a degree in Natural Sciences at Newnham College Cambridge.

For the majority of my career, I have delivered science and technology on behalf of the Ministry of Defence. Prior to joining the Met Office in December 2018, I was Acting Chief Technical Officer (CTO) and Head of the Cyber and Information Systems Division of the Defence Science and Technology Laboratory (Dstl). The division had many areas in common with our work at the Met Office including web and data science, space systems and weather, radar and other sensor systems. As CTO I oversaw Dstl’s entire £650m portfolio of research and trebled our pipeline of innovation and new intellectual property, a strong interest of mine.

I began my career as an armour researcher, developing novel armour systems to protect military vehicles, then led several groups in Dstl’s Physical Sciences Department before taking over as the department manager in 2009. During this time I was appointed Fellow of the Institute of Physics and served as a member of their governing council. I have been a visiting professor in Electronics and Computer Science at the University of Southampton since 2012.

At Dstl, I was the executive sponsor of our Gender Equality Network and an active straight ally for our LGBT network. As a site incident manager for Porton Down I was also a trained County Silver Commander for major incident response. A lifelong lover of the natural environment I was a trustee and honorary treasurer of Wiltshire Wildlife Trust until my move to Exeter.

Professor Stephen Belcher, Chief Scientist

The Met Office team of more than 500 research scientists has earned a world-wide reputation for excellence in weather and climate science and the translation of this science into weather and climate services for daily weather forecasts, emergency response (for example, to volcanic eruptions), and into climate change mitigation and adaptation. As Chief Scientist, I have overall responsibility for the leadership and management of this scientific programme, by providing strategic direction, ensuring high quality delivery and nurturing scientific excellence. I represent the Met Office on science and research technology to UK Government, ensuring that the Met Office science programme fits properly into the wider UK environmental science landscape.

I have a background in academic research, with 30 years of experience working on the fluid mechanics of the atmosphere and oceans at the universities of Stanford, Cambridge and Reading. In 2012 I joined the Met Office as Director of the Met Office Hadley Centre and led the Centre's evolution to focus on climate science and climate services. Whilst Director I initiated the Newton Fund Climate Science for Service Partnership, a research programme now supporting 100 scientists to harness the breadth of UK scientific expertise to build climate science and climate services.

Ian Cameron, Business Group Director

I am responsible for the services the Met Office provides to industry and associated public bodies. This includes aviation, surface transport, energy, infrastructure and retail, and covers both operational weather services as well as helping industry adapt to a changing climate.

I have worked at the Met Office in a number of roles since 1983 from weather forecasting for armed forces operations to managing transformational activities and product development, and recently leading the Met Office's UK and international services for aviation.

Tammy Lillie, Director of Human Resources



I am responsible for the design and implementation of the HR strategy to ensure we have the right people in the right roles performing at their best. The HR team delivers the full range of HR functions including organisational development, resourcing, employee relations, reward and benefits, diversity and HR administration.

Stephen Marshall, Interim Operations Director

I am responsible for the quality and delivery of the operational weather and environmental services that we provide 24 hours a day, 365 days of the year. I work closely with teams across the Met Office to ensure our world leading science is available to our operational meteorologists, and that they have the necessary skills and tools to provide services to support our customers, including the public, government and industry, both nationally and internationally. We want everyone to be able to make the most of accurate forecasts and expert advice to keep people safe and enable them to make the right decisions based on weather conditions that affect the activities they are trying to do. In addition, I am responsible for our International relationships, ensuring that we collaborate with our colleagues across the world, sharing resources, information and scientific excellence; the weather has no borders.

Charles Ewen, Director of Technology and Chief Information Officer

I am responsible for the development and implementation of our ICT Strategy and for the internal technical teams within the Technology Directorate. I also work closely with our Science teams to operate our High Performance Computing (HPC) capability and mass storage systems. The Met Office relies heavily on cutting-edge IT to improve the quality of forecast services and increasingly to make those services accessible and effective for customers and the public.

I have worked for the Met Office in a number of senior technology roles since 2008 and, prior to that, worked in the Business-to-Business online retail and distribution industry. During this time I used relevant technologies to transform businesses from traditional retail approaches to being internet and technology capable. As well as a number of consulting appointments, I worked within the Premier Farnell group of companies for over 10 years. I have run my own small technology company and started my career as an Electronics Engineer in the defence industry.

Andy Kirkman, Director of Government Services

I am responsible for all of the services that the Met Office provides within the public sector. This includes predictions on climate change; our services in support of our armed forces; advice on the spreading of airborne animal diseases; and 'free at the point of use' services we provide to emergency responders and the general public.

Nick Jobling, Chief Financial Officer

I am responsible for the delivery of all financial advice, planning, control and support to the organisation.

I am also the lead on a programme of Transformation and Efficiency to ensure the organisation is fit for the 2020s, and able to continue to deliver, resiliently, for all of our customers.

Before joining the Met Office in 2004 I had 17 years' experience across a broad range of financial disciplines in high-tech manufacturing and telecoms sectors after qualifying as a Chartered Accountant. I have previously worked at Cable & Wireless, Global Crossing and held a number of positions at Alcatel Submarine Networks.

Prof Simon Vosper, Director of Meteorological Science

I direct the Met Office's Meteorological Science and also have specific responsibilities for leading the Foundation science directorate, which consists of Atmospheric Processes and Parametrizations, Dynamics, Global Model Development, Observation Based Research and Science Partnerships.

I joined the Met Office in 2001 as a research scientist. Prior to this, I was based at the University of Leeds as a postdoctoral research fellow, latterly funded by the NERC postdoctoral fellowship scheme.

I completed a PhD on the behaviour of orographic internal gravity waves at the Department of Applied Mathematical Studies, University of Leeds in 1995. Following this, I worked as a postdoctoral research fellow on a number of projects at the School of Earth and Environment at the University of Leeds and at the University of Surrey

Simon Brown, Director of Services

I have spent the last 18 years working in the UK water industry that has a number of synergies with the Met Office such as delivering great customer outcomes and serving local and national communities.

My early career background started with a Geography and Geology degree and a Masters in Water Management and Technology, both from University of Birmingham. I joined Severn Trent Water in 2003, firstly in technical roles ranging from wastewater treatment technical support, asset management, operational delivery and capital delivery, and latterly undertaking leadership roles. These leadership roles have included responsibility for the 24-7 management of the water network, multimillion-pound commercial contracts, implementation of change programmes and strategic performance responsibility for Severn Trent’s performance framework across a number of key customer KPIs.

I moved to work in the water retail market- water competition for business customers- in 2016, firstly as part of the senior leadership team for setting up the largest company in the market- Water Plus. I had commercial responsibility for the Procurement function, managing customer promises by the UK water companies as well as working with the market regulator on market harmonisation. In 2018 I took up an Executive accountability for the design and set up of Water Plus’s transformation directorate and led an 18-month programme focussed on business and system improvements, digitalisation and a review of the IT infrastructure.
