Professor, group leader

I'm professor of atmospheric science & physics at INAR and Finnish Meteorological Institute. I'm also Director of the Doctoral program in Atmospheric Sciences. My expertise is in aerosol physics and I have wide experience with field and laboratory experiments on atmospheric aerosols and nanoparticle measurement techniques. I'm interested in processes altering the atmospheric aerosol and ion population, such as aerosol formation and growth. The main projects I'm involved in are ACTRIS and CLOUD.

Doctoral researcher

I am interested in the optical properties of aerosol particles, especially black and brown carbon, to calculate some of the input parameters that are required for better regional and global climate projections.

Research professor (tenure track)

I am tenure track research professor of aerosol and cloud processes at the Finnish Meteorological Institute and INAR. My work focuses on using in-situ observations to reduce aerosol radiative forcing uncertainty in global scale models. My background includes airborne and chamber observations, while my current modelling work focuses on EC-Earth.
