Paul Jackson

Managing Director

Dr Paul Jackson is a psychologist specialising in the impairment that accompanies tiredness, drug and alcohol use, with extensive experience as a consultant to both industry and government.

Paul has designed fatigue risk management systems and fatigue awareness training programmes for a range of clients including BP, Cargolux, Jetairfly, easyJet, Newmont Mining, Shell and Virgin Atlantic. He also leads Clockwork’s fatigue auditing service, in which capacity he has undertaken visits to mine sites and oil and gas installations in Australia, Angola, Egypt, Ghana, Indonesia, Libya, New Zealand, Oman, Peru, Qatar and the USA.

Previously, Paul was Research Programme Manager at the UK Department for Transport (DfT). During this time he served on the Secretary of State for Transport’s Honorary Medical Advisory Panel on Alcohol, Drugs and Substance Misuse and was the UK representative on the EU Expert Panel on Drugs and Alcohol.

In 2012 Paul was commissioned to write a series of reports for the DfT Advisory Panel on Drug Driving. Previously, Paul was invited by Sir Peter North to write a review of the current state of knowledge regarding drugs and driving in the UK and overseas. This report formed an integral part of the North Review of drink and drugs driving law.

A regular speaker at road and aviation safety conferences in the UK and overseas, Paul is also a highly experienced trainer, and is a Visiting Lecturer at Cranfield University. He also delivers the Joint Aviation Authority Training Organisation (JAA-TO) course ‘An Introduction to Fatigue Risk Management Systems’ for aviation operators, as well as a longer course for aviation regulators.


Paul completed his PhD at Imperial College, London, researching the effects of navigation systems on the development of cognitive skills. He also has a Masters degree in Environmental Psychology and a BSc (Jt Honours) in Psychology and Sociology.

Alexandra Holmes

Alexandra Holmes

Research Director

Dr Alexandra Holmes is Research Director at Clockwork Research, specialising in scientific safety cases and the implementation of Fatigue Risk Management Systems (FRMS) in aviation. With a PhD exploring the health effects of sleep loss and shift work, Alex is a current member of the ICAO Helicopter Fatigue Management Task Force and assists the UK CAA and Irish CAA to evaluate FRMS applications and safety cases.

Alex worked closely with easyJet to assist the company to become the first European airline to implement an FRMS. She has recently completed a two-year project with Southwest Airlines to implement the first system-wide FRMS in the US.

Alex has managed multiple Line Operations Safety Audit (LOSA) programmes and large research projects to explore the causes and consequences of pilot fatigue. She has undertaken scientific studies of the sleep, fatigue and performance of pilots working for Air France, Cathay Pacific and Qatar Airways.

Sarah Booth

Sarah Booth

Principal Researcher

Sarah Booth is Principal Researcher at Clockwork Research. A specialist in human performance in the aviation and aerospace environments, Sarah has worked with aviation operators to develop and implement Fatigue Risk Management Systems (FRMS) across multiple regulatory environments.

Sarah specialises in the integration of key data streams into the FRMS. A highly experienced user of biomathematical fatigue models, Sarah develops key metrics for the analysis of roster-related-fatigue levels and the determination of broader schedule quality. Sarah also works closely with operators to implement effective, data-rich fatigue reporting systems, and to identify barriers to reporting.

A regular speaker at both academic and industry conferences, Sarah is also a trainer, delivering to operators in the implementation of Fatigue Risk Management, as well as courses in the use of biomathematical modelling.

Sarah obtained an honours degree in Physiological Sciences from the University of Oxford, focusing on cardiovascular physiology and immunology and a Master’s degree in Space Physiology and Health at King’s College London. Sarah is an Affiliate Member of the Royal Aeronautical Society.

Camille Burban

Camille Burban

Senior Behavioural Researcher

Dr Camille Burban is a Senior Behavioural Researcher at Clockwork Research. She specialises in aviation human factors and safety investigations. Her role involves a wide range of tasks, including development of fatigue surveys and survey analysis, development of fatigue investigation processes, review and recommendations of procedures, scientific studies of roster patterns and the use of biomathematical models to conduct roster analysis.

Camille recently completed her PhD in Safety and Human Factors at the Safety and Air Accident Investigation Centre at Cranfield University, UK.  Her research examined the training needs for air accident investigators, and helped develop recommendations for investigation organisations on the extent to which investigators should be trained in human factors, the topics to be approached during such training, and the ideal attributes of a human factors expert involved in investigations. Whilst undertaking her PhD, she won the ISASI Rudolf Kapustin award and presented her research at several international conferences. She also lectured to Masters students and professional investigators at Cranfield University as part of her studies.

Camille has a long established interest in and passion for aviation safety, having previously obtained a Mechatronics engineering diploma from ENSIAME, France (Master’s degree), and an MSc in Human Factors and Safety Assessment in Aeronautics from Cranfield University (UK). Her MSc thesis focused on the way human factors was considered at the UK Air Accidents Investigation Branch.

We have been working closely with Clockwork since 2013. They have been instrumental in the airline successfully setting up an effective fatigue programme, through an in-depth analysis of the airlines operations and produced excellent training materials to improve the crew understanding of fatigue. The staff at Clockwork are extremely knowledgeable and professional, making it easy to achieve good results in reducing the risks associated with fatigue in our very complex quote

We embarked on a complex project with Clockwork and the team at Clockwork were receptive to our ideas and made sure they immersed themselves in our own company culture. This relationship building gave us the ability to give open and honest feedback from both parties which resulted in an excellent programme that our cabin crew could use that was appropriate to their roles and easy to relate quote
