PhD position in aerosol and cloud modelling as part of the CLOUD Marie Curie network

The School of Earth and Environment at the University of Leeds, UK, invites applications for a PhD position (36 months).

The position is connected to the EU Marie-Curie International Training Network CLOUD-TRAIN and is located at the University of Leeds, in the UK. CLOUD-TRAIN is a multi-site network of Early Stage Researchers and Experienced Researchers at 10 partner institutions across Europe. The overall aim is to investigate, with the CLOUD facility at CERN, the potential influences of galactic cosmic rays on clouds by modifying the abundance and properties of ions, vapours, aerosols, cloud condensation nuclei (CCN), and ice nuclei (IN). The PhD project at Leeds is concerned with the modelling of global aerosol and aerosol-cloud interaction, using new measurements from the CLOUD facility to improve the models and calculate climate impacts. The PhD student will use and develop existing state of the art models in close collaboration with members of the network. Students will also have the opportunity to undertake secondments to partner institutes and to work at the experimental facility at CERN.

An Early Stage Researcher means a researcher who, at the time of recruitment, has not yet been awarded the doctorate degree and is in the first 4 years (full-time equivalent) of his/her research career.

The position is open to applicants of all nationalities. At the time of recruitment, the researcher must not have resided or carried out his/her main activity (work, studies, etc) in the country of the beneficiary for more than 12 months in the 3 years immediately prior to his/her recruitment under the project. Compulsory national service and/or short stays such as holidays are not taken into account.

The post holder will be appointed under a full employment contract and receive a salary of €44,800 per annum. A mobility allowance depending on personal situation is also paid. Further details of the financial arrangements are available at

Please send your application to Michelle Lesnianski, m.lesnianski(at)

For informal enquiries, please contact Prof Ken Carslaw, k.s.carslaw(at)

Further information about the project and research group

The research will be carried out within the Aerosol Modelling group in the Institute for Climate and Atmospheric Science. Further details about the group’s research can be found at

The research will involve developing new mechanisms to describe aerosol formation and interaction with clouds, incorporating them in cloud models and global climate models, and using these models to assess impacts on climate. New experimental data from the CERN CLOUD chamber will be used together with ambient observations to understand the impact of nucleation on the atmosphere. A major theme within the CLOUD-TRAIN project is to assess the effect of ion-aerosol-cloud processes on climate and the potential for modulation of climate by cosmic rays. Advanced cloud models will be used to understand the evolution of cloud processes taking into account aerosol and cloud drop charging effects.
