Applications open for 2022 PhD studentships

Applications are now open to join the EPSRC CDT in Aerosol Science. At a time when Aerosol Science has never been so crucial, we work to equip the next generation of Aerosol Scientists with the skills needed to tackle the numerous multidisciplinary challenges that fall at boundaries between the physical, engineering and health sciences.

After spending the first year training as part of the CDT cohort at the University of Bristol, our students undertake PhD projects hosted at one of our seven institutions, the Universities of Bristol, Bath, Cambridge, Hertfordshire, Imperial, Leeds and Manchester. Could you be part of our fourth cohort?

Choosing your PhD project

Examples of potential PhD projects are available on this page. Each studentship has a primary academic supervisor at the home institution. A second academic supervisor (who may be at a second institution) will host the student towards the end of year 1 for a thematic broadening research sabbatical. In either year 2 or 3, each cohort member will undertake a placement with an industrial partner, further developing your skills and gaining experience of aerosol science outside academia.

All PhD projects and sabbaticals are designed in complementary thematic areas of aerosol science. The five themes are: basic aerosol processes; measurement techniques; aerosols and health; aerosol technology; and atmospheric and environmental aerosol.

On your application you can indicate preferences for specific theme(s) and/or institution(s) but this information is not essential and we appreciate your preferences may change. During the recruitment process, candidates will have the opportunity to learn more about specific projects and meet with potential supervisors.

What funding is available?

Each four-year PhD studentship is fully funded as part of the EPSRC CDT in Aerosol Science. Some projects are also part-sponsored by an industrial partner (in which case this will be noted on the project description). Successful applicants who meet the funding criteria will receive a studentship covering tuition fees, research and training support grant, plus a stipend paid at the standard UKRI rate. Both UK and overseas candidates are encouraged to apply.
