Aki Sinkkonen

Docent, leader

Docent Aki Sinkkonen is the head of the research consortium ADELE (Autoimmune Defense and Living environment, funded by Business Finland) that employs fifteen persons at three universities. His main research interest is the effects of our everyday living environment on health. ADELE consortium includes Professor Heikki Hyöty's and Professor Juho Rajaniemi's research groups at Tampere University. One of the central goals of ADELE is to utilize cross-disciplinary metadata to reveal novel associations between living environment and health. ADELE consortium and Docent Sinkkonen are collaborating with Principal Investigators at DIPP (Diabetes Prediction and Prevention; Professors Mikael Knip, Jorma Ilonen, Jorma Toppari, Riitta Veijola) and Ikihyvä (Good Ageing in Lahti region) projects as well as Professor Ari Jumpponen and PhD Raisa Valve.

Docent Sinkkonen’s long-term research interests cover the impacts of pollution on microbial communities and plant growth, soil remediation and the ecology of autumn leaf colors. His PhD thesis concentrated on the effect of phytotoxins on plant biomass at varying plant densities. His later studies have covered studies on soil remediation and the ecology of soil microbial communities in collaboration with Professors Rauni Strömmer and Martin Romantschuk. Together with University Lecturer Anna-Lea Rantalainen he has found out that low toxicant concentrations can shape plant populations even though mean size is not affected. Today, this research direction continues in collaboration with PhD Regina Belz. Together with Professor Jeffrey D. Weidenhamer, he has been exploring the consequences of density-dependence of pollutant effects on plants. Sinkkonen has also worked with plant invasiveness in collaboration with Professor Heikki Setälä, associate professor Vesa Hytönen and Professors Kitichate Sridith and Krittika Kaewchumnong. Autumn leaf colors belong to the most impressive displays in nature. As they may play a central role in tree growth and defense, Sinkkonen has investigated them in his spare time and collaborated with Professor Simcha Lev-Yadun and Juha Mikola. Sinkkonen’s other collaborators include Senior Researcher Pertti Pulkkinen, Dr. Tomasz Płociniczak, Dr. Sergio Sorbo, Dr. Magda Pacwa Plociniczak and Professors Polina Galitskaya, Svetlana Selivanovskaya, Onderj Cinek and Zofia Piotrowska-Seget. Sinkkonen is also co-operating with several enterprises, which have led to mutual benefits, i.e., new business models in the form of novel environmental technologies and possibilities to control environmental quality.

Riikka Puhakka

Docent, Academy Research Fellow

While Ph.D. Riikka Puhakka’s background is in cultural geography, she has experience of working in multidisciplinary research projects. Currently she is studying the health and well-being impacts of outdoor recreation among youth in NATUREWELL project. Recently she has studied how greening of the kindergarten yard affects children, and how interested are consumers towards novel health-enhancing products. She has also studied the perceived health and well-being impacts of Finnish protected areas, and young people’s outdoor recreation and relationships with nature. Before starting at the University of Helsinki in 2013, Ph.D. Puhakka worked as postdoctoral researcher at the University of Oulu and studied different aspects of nature-based tourism. In 2007 she finished her Ph.D. research related to the role of tourism and recreation in national parks in the University of Joensuu. Her list of publications includes 30 peer-reviewed research papers which examine human relationships with nature from different perspectives.

Mira Grönroos

Postdoctoral researcher

Ph.D. Mira Grönroos is interested in the interplay between environmental quality, microbiota and human health. For instance, she studies how urbanization affects the microbiota in the surroundings of homes and the microbiota of the human residents. Further, she examines how the diversity and composition of the environmental and human microbiota affects human health parameters. She has a broad background in biological sciences including community ecology, aquatic invertebrates and limnology. Before starting her post doc in ADELE- and NATUREWELL-projects, Ph.D. Grönroos worked in Finnish environment institute in Oulu where she also prepared her PhD-thesis. Grönroos defended her thesis in University of Oulu in 2015. In her thesis, she studied the metacommunity structuring of stream organisms.

Anirudra Parajuli

Postdoctoral researcher

Anirudra Parajuli’s Master’s degree involved the investigation of biotechnological and therapeutic potential of bacterial natural products. In his Ph.D study, he aimed to utilize his previous knowledge in Pharmaceutical science and microbial biotechnology to explore the dynamic relationship between environmental pollution, human and environmental microbiome and human health. Specifically, he is interested in studying how persistent organic anthropogenic pollutants like the polyaromatic hydrocarbons (PAHs) affect the abundance and diversity of the bacteria associated with the human immune system, both in the living environment and in human body.

Juulia Manninen

Doctoral researcher

MSc Juulia Manninen is currently conducting her PhD, focusing on the urban environment's microbial diversity and its associations with the human microbiome, health, and immune-mediated diseases. Her primary interest lies in the role of biodiversity in rebalancing the dysbiosis of the human microbiome. She has a background in bio- and environmental technology, with a specialization in environmental microbiology. Manninen works in the Human Exposomic Determinants of Immune Mediated Diseases (HEDIMED) project, which receives funding from the European Union's Horizon 2020 program.

Mika Saarenpää

MSc Mika Saarenpää’s PhD project looks into the connection between outdoor recreation and human microbiota, both in urban and natural settings. Topics that are of interest to him include connectedness to nature, health effects derived from nature experience, and sustainability. He has an interdisciplinary background in environmental sciences, accompanied with experience in circularity, environmental legislation and education, GIS, Green Care, and biodiversity issues. With his research he wishes to emphasize the importance of biodiversity and well-functioning ecosystems for human health.

Nan Hui

Docent

Dr. Nan Hui defended his PhD thesis in the Department of Environmental Sciences, University of Helsinki in 2010. The PhD study, supervised by Prof. Martin Romantschuk and Prof. Rauni Strömmer, is about Microbial Diversity in Pb Contaminated Forest Soil. As a researcher, he worked very efficiently, showing great initiative both in reporting the results in scientific articles and applying research projects. Although Dr. Nan Hui has spanned a wide area of microbial and environmental issues (e.g. heavy metal contamination, compost, soil pollution and bioremediation, urbanization, plant functional groups), he has always been the expert in the area of statistics (R and SAS), DNA sequencing analysis (NGS), bioinformatics (Mothur, Galaxy) and DNA based microbial community analysis. Of particular interest for the microbial ecology is that he has been responsible for screening the bacterial communities in relation to environmental health. Here he has found, in collaboration with his coworkers that the abundance and community composition of proteobacteria in the environment appears to play an important role in the wellbeing of the local residents.

Ville Selonen

Postdoctoral researcher

Ph. D. Selonen was responsible for plant community inventories in the Adele strategic research opening; this information is being utilized in analyzing the associations related to the incidence of type 1 diabetes, allergies and other immune system disorders in the ADELE research. After completion of the task, Selonen has focused on the remediation potential of meat-bone-meal. He has successfully – together with Docent Kari Steffen – investigated the potential and fine-tuned the technology needed for soil remediation.
