The strength of spatial analysis and Geographic Information Systems (GIS) is in their ability to reveal and simplify complex and extensive phenomena to understandable and manageable forms. My GIS based research covers the fields of geoinformatics, transport geography, regional science as well as population and economic geographies. My work consists of academic, development and management duties in national and international projects. The analytical basis of my work is in applying and developing GIS methods for exploring, planning and optimising processes and structures in geographic context. My GIS analytical experience consists of four main fields: 1) network based accessibility analyses and method development in this field, 2) spatial-statistical/geo-spatial modelling 3) map production and 4) implementation of large computations by programming. Furthermore, by mixed use of geo-spatial and qualitative approaches, even more powerful composition is formed to tackle problems in dynamic society.
SOLOGS - Vähähiilinen SOTE-lähipalvelulogistiikka
This project aims to develop carbon efficiency of social and healthcare service network by bringing new knowledge about reasonable service locations and efficient patient and material logistics. As subtasks, the project develops the entity of social and healthcare services in Northern Ostrobothnia region from the viewpoints of customer accessibility, market potential and logistics service network. New solutions for thin material flows with long distances are sought through transport integration. Also, the project develops opportunities for geographically mobile services in the region. See SOLOGS pages.
Global geographic accessibility to food resources: Exploring spatial mismatch between food production, consumption and transport system by using big and open source data
Despite of satisfactory level of global food production, shortage of food is still a huge problem in some of the less-developed countries. Future climate change, population growth and conflicts likely increase the problem, whereas developing farming practices and opportunities to boost fair markets may ease off the hunger problem. However, regional balance between production and consumption, as well as differences in transport system conditions among regions, have a key role in satisfying demand. Aim of the study is to explore spatial mismatch between proxies of food production and consumption in accurately localised data. Two year project is funded by Kone Foundation. See project pages.

Improving the information base and optimising service solutions to support social welfare and health care reform (IMPRO)
Impro is a multidisciplinary research project seeking to develop new analysis methods for evaluating health and social services, and to support the development of more equal and cost-effective services.Funding by the Strategic Research Council (SRC) and the Academy of Finland. See IMPRO pages.
Opportunities and effects of mobility and multi-locality (Alueellisen liikkuvuuden ja monipaikkaisuuden mahdollisuudet ja seuraukset)
Study surveys state and magnitude of mobility and multi-locality in Finland by different perspectives. Particular attention is paid for work related mobility patterns and exploring individual, work place related and regional characteristics affecting to both phenomena. Funding by VN TEAS.
Quantification and valuation of ecosystem services to optimize sustainable re-use for low-productive drained peatlands (LIFEPeatLandUse)
Aim is to produce GIS based maps to demonstrate the predicted impacts of peatland re-use options on ecosystem services within project LIFEPeatLandUse. Funding: LIFE+ Environment Policy and Governance (LIFEPeatLandUse).

Balancing Local Politics, Housing Preferences and Sustainability in the New Detached Housing Areas in the Rural-Urban Interaction Zones (BALANCE)
The geography reserach unit's sub-project considered development paths in different new villages in the context of housing preferences, and more precicely how have the positive and/or negative development paths of different urban regions effected to the housing preferences of inhabitants in the new villages? The GIS based analyses focused to reveal migration patterns of skilled labour in relation to regional competitiveness.
Accessibility of sports facilities (LINDA) (Liikuntapaikkojen saavutettavuusindeksi)
LINDA project developed accessibility measures for sport facilities in Finland. Accessibility indices may be applied in monitoring success of sport policies in municipalities and measuring coverage of sport facilities and their regional differences. Funding: Ministry of the Education and Culture

Healthy Suport Services (Terveet tukipalvelut - Tehokkaat ja käyttäjälähtöisen tukipalvelumallit pitkien etäisyyksien terveyspalvelujärjestelmissä)
Healthy Support Services (Effective, user-centered and scalable support service models in long distance health care systems) project is close to health care systems in sparsely populated areas with long distances. Instead of developing existing systems, effectiveness is sought by producing services that are based on actual value for the main functions in health care. In this project we concentrate on value creation of support operation and scalable service model for areas with long distances without organizational barriers. Funding: Finnish Funding Agency for Technology and Innovation (TEKES)
Local and organic foods have gained a larger share of the markets in Finland during the last years. Potentials to increase the use of local food have strong connections to accessibility. The RuokaGIS project will use geospatial analysis and geographical information systems/science (GIScience) to reveal location and accessibility patterns of local and organic food at the province of Northern Ostrobothnia, Finland.

TRACC: Transport Accessibility at Regional/Local Scale and Patterns in Europe (2010-2012)
TRACC aims at taking up and updating the results of existing studies on accessibility at the European scale, to extend the range of accessibility indicators by further indicators responding to new policy questions, to extend the spatial resolution of accessibility indicators and to explore the likely impacts of policies at the European and national scale to improve global, European and regional accessibility in the light of new challenges, such as globalisation, energy scarcity and climate change. See ESPON TRACC pages.
The project is leaded by the Ministry of Employment and the Economy with the Ministry of Agriculture and Forestry. The aim of the project is seek to define new regional typology to Finland. Previous typologies are enhanced with grid data based approaches. Participating organizations are Agrifood Research Finland (MTT), Finland’s environmental administration (SYKE), Finnish regional research (FAR), Joint authority of Kainuu region, Ruralia Institute at University of Helsinki, Statistics Finland, Technical Research Centre of Finland (VTT), University of Eastern Finland, University of Oulu, and University of Tampere.
