Lisa Moussaoui, Ph.D. Founder

After studying Applied Psychology at Geneva University, I have done a doctoral thesis on collective pro-social behaviours (blood donation and pro-environmental behaviours) under the supervision of Pr. Olivier Desrichard. I defended my Ph.D. thesis in 2017, before going to Australian and Belgium Universities to gain broader research experience. Upon my return, I am a lecturer and research and teaching fellow at Geneva University. My classes focus on behaviour change techniques and intervention evaluation.

Since 2019, I run in parallel a consulting activity for various partners (Public administration, international organisations) with projects involving behaviour change for health promotion and pro-environmental behaviour. The company Behaviour Change Expertise was founded in order to perform this consultancy activity.

Barbara Kaiser,Ph.D.

– Psychologist

Doctor of Psychology since 2008 and holder of a university diploma in cognitive and behavioural therapy, I began by practising in the field of behavioural disorders and poly-drug use with adolescents entrusted to social assistance. In the context of youth health promotion, and more specifically contraception, I also had the opportunity to intervene for the Maison des adolescents de Savoie. As a professor at the Geneva University of Health Sciences for more than a decade, I developed a course on motivational interviewing as an intervention tool (smoking, alcohol consumption, drug addiction, nutrition, domestic violence, chronic diseases). During this period I started to train health professionals in psychoeducational interviewings using simulation with standardised patients. My research activities have focused on the determinants of health behaviour, particularly in the perinatal context (physical activity, nutrition, screening) and the development of professional know-how and skills. I have been a lecturer at the University of Geneva since 2019, where I teach motivational interviewing as well as risk prevention and health promotion. I am also in charge of the development of simulated interactions curricula and I am a speaker in several continuing education courses, in particular for Behaviour Change Expertise.

Msc.- Psychologist

During my studies in social and applied psychology at the University of Geneva, I did a dissertation on the explanations of smoking relapse in postpartum women under the supervision of Prof. Olivier Desrichard and Lisa Moussaoui. After working on a campaign to prevent youth suicide at the STOP SUICIDE association, I returned to the issue of tobacco by working at Behaviour Change Expertise, creating prevention messages to reduce consumption among 15-34 year olds.

At the same time, I regularly work with children and teenagers in the field of teaching and socio-cultural activities and offer creative writing workshops for all ages.

Msc.- Psychologist

Because I have always been passionate about human thought, I naturally turned to studying psychology. In 2020, I completed my master’s degree in applied and social psychology at the University of Geneva.  This master taught me how to develop interventions and prevention projects using techniques approved by the literature as well as how to evaluate their quality using statistics. My specialization in social psychology give me a vision of social issues that is often essential to take into account during interventions. I did an internship at WWF during which I developed pedagogical animations on various ecological themes. I also did a research paper to study the determinants of men’s commitment to gender equality. Today, I am interested in the promotion of health and ecological behaviours as well as in the prevention of discrimination of all kinds. My work at for Behaviour Change Expertise consists of formulating recommendations based on scientific literature to promote pro-environmental behaviour.

Nina Baehler,

Msc.- Psychologist

Passionate about understanding psychological and social phenomena, I obtained my master’s degree in applied psychology at the University of Geneva in June 2019. I completed my research thesis on collective pro-social behaviours (health, environment, donations to charities) under the direction of Lisa Moussaoui. In parallel with my studies, I worked as a research assistant on pro-environmental behaviours in the Consumer Decision and Sustainable Behaviour Lab. I was also a project assistant for the Behaviour Change Lab Sàrl on the theme of street harassment.

I am currently working at Behaviour Change Expertise since April 2020. I make recommendations based on scientific literature in order to support the development of educational activities on the subject of behaviours related to waste among secondary school students in Geneva. Alongside this activity, I am responsible for research, monitoring and evaluation of projects within Groupe sida Genève since September 2019, an association for prevention and promotion of health as well as the fight against social inequalities in health.

Msc.- Psychologist

My university studies led to a degree in social and intercultural psychology at the University of Lausanne. Fascinated by behavioural sciences and their application to environmental and health issues, my research thesis focused in particular on the promotion – based on the use of social influence methods – of a website providing environmentally friendly actions.

Thus, driven by the motivation to apply this scientific knowledge to the concrete world, I was able to test a digital intervention method aimed at facilitating the adoption of pro-environmental behaviours during an academic internship at the Behaviour Change Lab. Moreover, a collaboration between SIL and the University of Lausanne resulted in my engagement as a researcher in order to replicate this study in the city of Lausanne. In the same vein, I intend to promote recycling behaviour during my engagement at Behaviour Change Expertise.
