Meet The Team

The NAQTS team has over 30 years’ experience in public policy, engineering, chemistry, physics, business development, marketing and sales, as well as in the development of emissions monitoring equipment. The team also has a comprehensive network in place with industry, government, and academia. The team has published in scientific journals, been granted patents and awards, and is internationally respected in the community. Moreover, the team has a passion to inspire people to take ownership of their environment and quality of life. Whether that’s by improving homes through monitoring, or helping to develop informed public policy.

Douglas Booker  Founder & CEO

Douglas, a University College London graduate, launched NAQTS with the intention of: raising general public awareness of the health issues associated with indoor air pollution, assisting the public in improving their home air quality, and providing scientific data for policy advancement.

Driven by the pursuit of social justice, Douglas is also currently enrolled in a part-time PhD at Lancaster University investigating the relationship between socioeconomic status and indoor air pollution exposure, as environmentally it is often people from poorer backgrounds that are disproportionately affected by air pollution.


Dr. David Booker  Consultant

David specialises in aerosol physics and emissions monitoring and has worked with a number of key companies and regulators, including: UKAEA, AEA Technology, Booker Systems Ltd, and currently Sensors, Inc. in the USA. David is with this application, turning the clock back to some of his previous roles, and he is excited about helping the team to make a difference.





Simon Booker  Engineering Manager

Simon has been involved in mechanical and electrical design for over 30 years, with experience coming from Marconi, Castlet, Control Techniques, and more recently Quark Electronics. His passion for designing and building things, as well as walking and green open spaces has made this project a lot of fun for him.





Charlotte Farr PhD Researcher

Charlotte has just begun her PhD at Lancaster University and will be using NAQTS V1000 units to monitor indoor air pollutant levels in order to generate models that address improvements in building design, whilst managing the conflicts of energy efficiency and good indoor air quality. She is looking forward to helping the wider public improve indoor environmental quality, whilst maintaining energy efficiency and reducing their carbon footprint.




Scott Lowther PhD Researcher

After having completing his Undergraduate BSc in Environmental Sciences and having already worked with NAQTS on a “Work Placement Dissertation” and an internship. Scott is rejoining the team by starting a PhD at Lancaster University, and will be using the NAQTS V1000 units to measure Particle Number Concentrations in buildings in Guangzhou, China, to quantify the effectiveness of indoor air pollution mitigation techniques. Scott will also have the full support of the Guangzhou Institute of Geochemistry and the Chinese Academy of Sciences during his PhD.
