Personal profile
Short presentation
I am an assistant professor in Experimental Atmospheric Physical Chemistry at the Department of Chemistry. I recieved PhD in atmospheric sciences from University of Helsinki.
Primary fields of research
Research in my group covers a wide range of topics within atmospheric chemistry and physics. Specifically, we are interested in the formation of large low-volatility vapors in the air that facilitate molecular clustering and growth to aerosol particles. Aerosol particles play an important role for our health and climate and hence it is important for us to understand how they form and evolve. We employ mainly experimental approach by conducting laboratory and field investigations.
Teaching
I am course responsible for MSc course "Air Pollution and Health". In addition, I am also teaching on MSc course "Modern Atmospheric Chemistry" and PhD toolbox course "Scientific Writing - Writing Groups for Publications".
