PhD Position in Atmospheric Aging and In-Cloud Scavenging of Micro- and Nano-Plastic Particles Empa (Swiss Federal Laboratories for Materials Science and Technology) in Switzerland

Empa, a leading research institution within the ETH Domain, invites applications for a fully funded PhD position in the Laboratory for Air Pollution / Environmental Technology, in collaboration with ETH Zurich. This four-year project, supported by the Swiss National Science Foundation (SNSF), focuses on investigating the atmospheric aging and in-cloud scavenging processes of micro- and nano-sized plastic particles (MNPs) through advanced laboratory experiments. The research aims to deepen the fundamental understanding of how plastic aerosols interact with clouds, their environmental fate, and the mechanisms regulating their life cycle and wet deposition in the atmosphere.

Micro- and nano-plastics are an emerging global concern due to their adverse effects on ecosystems, the environment, and human health. This project addresses the urgent need to track and characterize the atmospheric behavior of these particles. The successful candidate will be based at Empa in Dübendorf, Switzerland, and will have access to state-of-the-art infrastructure and joint research resources at both Empa and ETH Zurich. Key tasks include preparing atmospheric-relevant MP and NP aerosol samples, simulating atmospheric aging, characterizing physiochemical properties, and testing ice formation abilities using specialized instrumentation.

Applicants should possess a Master’s degree (or equivalent) in chemistry, physics, engineering, atmospheric/environmental sciences, or a closely related field. Preferred experience includes analytical techniques for aerosol properties, micro- or nanoplastics, and ice nucleation experiments. Strong programming skills (Python, R, MATLAB, or IGOR) and excellent English communication abilities are required. The position offers a competitive salary, outstanding career support, and opportunities for personal and professional development within a collaborative and inclusive research environment.

The PhD position is fully funded for four years, with a start date in September 2026. Applications are open to highly motivated and talented candidates who are passionate about innovative, sustainable, and meaningful research.
