About me
I am a postdoc at the Aerosol Physics Laboratory of Tampere University. I completed my PhD in 2023 in aerosol physics and M.Sci. degree in 2016, in the Energy and Environmental Engineering Program of Tampere University of Technology.
I am currently working on air quality in urban areas, both indoors and outdoors as well as particle emissions.
