Air quality (AQ) –group people.
Pauli Paasonen, 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, vis­it­ing 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.

Jing Cai

I am a post-doctoral researcher interesting in the measurements of chemical and physical properties of aerosols. And now I am focusing using ACSM and CIMS to analyzing those properties.

Dian Ding

I am a post-doctoral researcher interested in anthropogenic aerosol emissions, air quality modeling, and air pollution-control response. Now I am focusing on anthropogenic particle number emission and its implementation in global integrated assessment model.

Wei Du

I am a post-doctoral researcher with interest in chemical and physical characterization of ambient aerosols. I’m now focusing on the growth processes of the new formed particles.

Pak Lun Fung

My doctoral study focuses on the derivation of air quality parameters proxy in urban regions. Currently, the approach is more in the statistical side and I would like to carry this further to physical way based on the interaction of the different variables in urban atmosphere. My interests also include remote sensing and machine learning techniques.

Shahzad Gani

Postdoctoral researcher seeking to understand the sources and processes that drive air pollution. Key interests: (i) Atmospheric science: aerosol dynamics, chemistry and meteorology, (ii) Air pollution measurement: fixed site and mobile monitoring, (iii) Air pollution exposure, (iv) Environmental justice, (v) Science communication.

Simo Hakala

I'm currently working on my master's thesis which is about new particle formation and shrinkage events in Saudi Arabia. I did my bachelor's on the growth of sub 3 nm particles in CLOUD 4 -experiments. Other than that, I have been doing NPF event classification for Hyytiälä.

Merli Juust­ila

I am a PhD student focusing on risks of energy production in Finland. My work includes life cycle analysis for different ways to produce energy but also takes into account people and risks that they face during the entire life cycle. I'm also secretarial science at Future Earth Finland which is a national committee for global chance research. I teach career courses for physic students and have a lot of interests science communication.

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.

Santeri Tuovinen

I’m a PhD student 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.

Salla Sillanpää (until end of 2020) Now at Finnish Meteorological Institute

Lubna Dada (until end of 2020) Now at Paul Scherrer Institute

I am interested in new particle formation events in various locations globally, as well as CLOUD chamber experiments at CERN. I like traveling, good coffees and french fries.

Kaspar Dällenbach (until summer 2020) Now at Paul Scherrer Institute

Particulate air pollution has severe impacts on human health. Studying the sources contributing to the aerosol burden is an essential part for mitigating these effects. I am interested in the origin, sources and formation processes, of the secondary organic aerosol which contributes to the particulate matter in strongly polluted regions.

Lian Xue (2019-2020)

I’m a PhD student of Nanjing University, and currently a visiting student in University of Helsinki. My research interests are the multi-scale variabilities of atmospheric constituents under circulation anomalies of climate systems, and the anthropogenic and natural emissions contributions in these processes.
