People

Air quality (AQ) –group people.
Pauli Paasonen, associate professor, group leader

I work in INAR as an assistant professor in Air quality – weather – climate interactions. My main research interests are in atmospheric aerosol formation, anthropogenic aerosol emissions and their climate effects. I work between experiments and large scale models, producing parameterisations from existing measurements, analysing comprehensive multi-variable data sets, and comparing data sets from different parts of the world to each other and to model results. I lead the Air Quality guidance group and I am the vice-director of the Doctoral Programme in Atmospheric Sciences at the University of Helsinki.

Tareq Hus­sein, pro­fessor

I am, generally, interested in Air Quality but have a wide interest about aerosols and their sources, transformation, and fate. Exposure is the ultimate goal in my research and within an international network of collaboration I am trying to develop models aiming at forecasting Urban Air Quality and assess the personal exposure (both indoors and outdoors). I am currently a Visiting Professor at the Institute for Atmospheric and Earth System Research but I am also a Professor of Physics at the University of Jordan.

Santeri Tuovinen

I’m a post-doctoral researcher in aerosol physics. My focus is on studying atmospheric new particle formation using theoretical methods, modeling of the dynamics of atmospheric clusters, and data-analysis.

Aino Ovaska

In my doctoral studies I focus on aerosol-cloud interactions. My work is related to aerosol particles that can act as cloud condensation nuclei and affect cloud properties. I am especially interested in the role of anthropogenic emissions in cloud formation and how this is represented in models.

Xiang Li

I'm a doctoral researcher in atmospheric sciences. I mainly focus on the influence of air mass exposure to anthropogenic and biogenic emissions on aerosol particle number size distributions in various environments. My research is to delve into the contributions of direct emissions and secondary aerosol formation, quantifying effective mitigation solutions across varying degrees and types of environments. 

Lian Duan

I am a visiting Ph.D. student from Fudan University, China, with a research focus on carbonaceous aerosols in megacities of eastern China. My primary interests lie in the characterization, source apportionment, and health risk assessment of these aerosols. I am also interested in utilizing statistical and mathematical modeling techniques to evaluate the potential adverse health effects on residents exposed to prolonged high levels of black carbon.
