Mohsen Kazemimanesh

Senior Scientist

Mohsen Kazemimanesh is a Senior Scientist in the Air Quality and Aerosol Metrology (AQAM) Group at the National Physical Laboratory (NPL). Mohsen leads NPL’s work on measurement and physicochemical characterisation of novel and emerging sources of airborne particles (aerosols) by different metrics such as particle size distribution and number or mass concentration. This work involves extending the size range of calibration aerosols beyond the state of the art, in line with the requirements of future standards and regulations. He also leads NPL’s work on technologies used for the regulation of particle emissions from automotive and aviation industry, including volatile particle removers (VPR) and portable emissions measurement systems (PEMS). Mohsen’s current research interests include: 

  • Characterisation, quantification and environmental impact of non-exhaust emissions from vehicles 

  • Developing testing facilities for validation of low-cost air quality sensors for ambient and indoor air 

  • Developing novel and improved calibration techniques for the measurement of particulate matter (PM) in air beyond the state of the art. 

Mohsen has more than a decade of solid experience in aerosol science and engineering. He has a PhD degree in mechanical engineering from University of Alberta, where he also completed his Master of Science in the same field. Prior to joining the AQAM Group at NPL, he was a postdoctoral researcher at the University of Cambridge. His previous research in academia focused on a wide range of topics in aerosol science and technology. This included using novel techniques to measure and characterise harmful particle emissions from various combustion sources (e.g. gas flares in oil and gas industry, vehicle and aircraft engines, and tobacco smoke) as well as non-combustion sources (e.g. brake and tyre wear emissions). Mohsen’s research also included development of aerosol generators and measurement sensors, as well as using aerosol-based methods for the generation of useful engineered particles for net zero and sustainable applications.  

Mohsen is a committee member of the UK and Ireland Aerosol Society since 2021, co-chair of Working Group 1 on Aerosol Technology in the European Aerosol Assembly since 2020, and a member of the American Association for Aerosol Research since 2017. He has served for the European Aerosol Conference as a member of the organising committee in 2021 and as session chair in 2020, 2021 and 2023. Mohsen was the Chair of the 2023 UK Annual Aerosol Science Conference and is a peer reviewer for top-tier journals in the fields of aerosols, atmospheric sciences, combustion and energy sciences, and sustainability.
