Ari Haukkala was University lecturer in social psychology. His research program focused on three main areas, 1) psychosocial factors in health and well-being, 2) theory-based behaviour change interventions, and 3) psychosocial aspects in genomic research.

His research projects included  where the aim is to examine how health-related genetic information is understood among laypeople and what people do with genetic information. He was also involved with study by National institute of Health and welfare and Finnish Lynch syndrome study.

Another project was related to mHealth, where it was examined how it is possible to embed theory-based behaviour change techniques to mHealth application in EU funded .

He taught courses related to social psychology, behaviour change and quantitative research methods.

Keegan is a health psychologist with interests in the motivational processes that underlie health behavior change, and in understanding how individuals make use of interventions to change their behavior. He currently works in the , which aims to understand how the quality and quantity of motivation fluctuate over time, in order to identify ideal moments to deliver motivational interventions.

In the past, Keegan has worked on several meta-analyses to identify intervention components associated with increases in motivation, physical activity and weight loss maintenance.  He has also developed interventions to promote physical activity among individuals with rheumatoid arthritis and among people with excess risk of cardiovascular disease. These projects involved developing (mhealth) behavior change tools for patients and developing interventions to train healthcare providers to deliver motivational interviews in practical settings.

Elina's main research interests lie in the fields of interaction, agency, motivation, well-being and behaviour change.

Her current research focus is primarily on motivational interaction and the changing of motivating style. She analyses the data from  that disseminated and implemented evidence-based intervention strategies into practice. She coordinates the network. Disseminating social psychology research is close to Elina's heart.

Elina has worked extensively in the field of alcohol research. Her doctoral dissertation discusses attitudes toward alcohol screening and counselling in social work. Her future research topics in this area involve the construction of alcohol-related problems.

Katri Kostamo is a postdoctoral researcher in the Social Psychology discipline at the University of Helsinki, Finland. Having previously been employed in the areas of health promotion, quality assurance, and knowledge management, she currently applies various mixed methods (triangulation, realist evaluation, and a qualitative survey) for process evaluation of interventions targeting people’s life style changes. This work has been funded by Juho Vainio Foundation and by a collaborator funded by Business Finland. 

Katri is especially interested in improving research effectiveness by evaluation, implementation and dissemination, thus increasing research relevance for policy and practice. Her doctoral dissertation explores physical activity by identifying critical incidents related to behaviour change. Focusing on critical incidents in storytelling can facilitate making conclusions about important components in behaviour change interventions.

Before starting his PhD, Matthias Aulbach worked in addiction counseling and therapy, intensifying his interest in impulsive behavior and behavior change.

Thus, his main research interest is in dual-process models and in his PhD he is aiming to change impulsive determinants of eating behavior using computer-based tasks. In his research, he uses meta-analytical and experimental methods, including an excursion to the wonderful world of EEG-measurement. Matthias’s PhD project has received funding from the Finnish Cultural Foundation and the Signe and Ane Gyllenberg Foundation.

In addition, Matthias has worked in Ari Haukkala’s project on as well as Nelli Hankonen’s where he was mainly occupied with data analysis and such.

Currently, Marguerite is researching the psychological mechanisms behind uptake and maintenance of well-being enhancing behaviors, e.g., mindfulness practice, among adolescents. She has previously worked with a variety of subjects in social psychology including subjective well-being, culture, income inequality, justification theory, moral and political psychology, motivation for physical activity, the role of literature in evoking sympathy/empathy, self-enactable motivation and behavior change techniques, and experimental frameworks for governments.

Projects: , 

Prior to academia, Matti worked in media, sales and marketing research. Now, as a cargo-cult complexity scientist, he is examining how complexity theory can contribute to helping people change their health behaviour. More specifically, he is working on how to evaluate the effects of intervention field trials, along with a more idiographic approach to studying and changing motivation. He balances PhD-ing with meditation and combat sports, and blogs about scientific methodology.

Johanna got intrigued by the opportunities that digital technologies offer for behavioural sciences while developing online courses within the Geneva Foundation for Medical Education and Research (WHO collaborating centre). At the University of Helsinki, she worked for an and a three-year doctoral project designing, developing and testing a digital health platform as part of a multidisciplinary, EU funded consortium .

Johanna is currently analysing intervention data of smartphone interventions with n-of-1 multilevel models and qualitative evaluations. She has conducted research with systematic review and meta-analysis, psychophysiological measures, surveys, interviews, and usability studies with think-aloud methods.

Johanna is interested in factors that support behaviour change, including motivational and self-regulatory elements related to self-determination theory and motivational interviewing. She enjoys developing gamified solutions to support engagement in health behaviours through challenges and fun.

Otto Halmesvaara currently works in the project and is involved in the study as part of Ari Haukkala's team. Otto's expertise includes quantitative methods and experimental study of emotions.

Melina is a licensed psychologist and qualified occupational health psychologist, in addition having a background in sport and exercise psychology. Before starting with her PhD, Melina had been working as an occupational health psychologist with experience in multiple health-related issues.

Melina is especially interested in motivation and behaviour change, and she shares a passion for sport psychology. Currently, Melina is working with her PhD on motivational interaction and professional's behaviour change in the context of exercise and sports. Melina is a part of Nelli Hankonen's research group.
