About me
I am Associate Professor (tenure track) in Bio and Circular Economy. I lead a research group Microbial Electrochemical Technologies and am also part of research groups Wastewater and Waste Engineering for Circular Economy and Water Engineering. The research of these groups focuses on environmental biotechnology and industrial biotechnology applications that enable environmental protection as well as resource recovery. My research currently focuses on microbial electrosynthesis and biomethanisation of chemicals and biofuels from carbon dioxide, anodic electrofermentation, nutrient recovery from wastewaters with, e.g. (bio)electrochemistry or hydrothermal carbonisation, and characterisation of microplastics in sludge samples. I am also doing multidisciplinary research in research projects CICAT2025 and UPCE.

Aerosol Physics
Jorma Keskinen
- Professor
- Head, Aerosol Physics Laboratory
- Faculty of Engineering and Natural Sciences
- Tampere University
- +358401981003
- jorma.keskinen@tuni.fi
About me
I am a professor of Physics. Specializing in Aerosol Physics, I lead the Aerosol Physics Laboratory .
Aerosol particles strongly affect the radiative forcing of our climate, while exposure to particulate matter forms a major global health problem. Our laboratory studies the aerosol processes, sources, and emissions, as well as effects on air quality and atmosphere. My own research interests cover aerosol measurement techniques, emissions of engines, vehicles, and ships – especially nanoparticles, volatility, and secondary aerosol formation potential.
Responsibilities
Head of Aerosol Physics Laboratory
Head, degree programme in Engineering and Natural Sciences
Board member, Aerosol Research Foundation
Member, National INAR council, Institute for Atmospheric and Earth System Research
Miikka Dal Maso

- +358503377914
- miikka.dalmaso@tuni.fi
About me
My research tries to answer the question of how the emissions from man-made aerosol sources evolve in the atmosphere and how they affect climate and air quality. This involves detailed charaterization of the emitted aerosol with latest methods, experimental simulation of the atmospheric dilution and oxidation processes, and numerical modeling of the physical and chemical transformations the aerosol experiences in its life-cycle. We use atmospheric mass spectrometric methods (CI-TOF-CIMS and FIGAERO-CIMS) in emission and mobile settings.
Responsibilities
I lead TAU activities in the Atmosphere and Climate Competence Center Flagship project. I teach the courses Aerosol Physics, Aerosol Measurement Techniques, Aerosol Modelling and Climate.now.

About me
I am a professor of aerosol physics and a leader of the research group which focuses on experimental research related to particle emissions and air quality. By means of our research, we aim at understanding of the formation of particle emissions, their transformation in the atmosphere, and their effects on air quality, human health and climate. We see that this information and knowledge is crucial when minimizing the anthropogenic air quality and climate effects.
