Manuel has a BSc in Sociology by the Pontificia Universidad Católica de Chile and specialist training in psychometric and discourse-analytical methods. He has worked on diverse topics such as classic theoretical psychology, subjective ageing, and undergraduate and graduate students’ wellbeing using mixed quantitative and qualitative research methods. The core interest linking the diverse projects Manuel has worked in is to develop theoretical and methodological contributions to a transdisciplinary approach to social life with mixed research techniques. He has taught social theory and research methods to psychology and sociology students in Chile, developing educational instruments to promote the direct study of works by classical authors in each field.

Over the last years, Manuel has focused his work on ageing using qualitative methods within a discursive and dialogical framework. He has also worked as an assistant researcher and analyst using quantitative methods (CFA, SEM) in wellbeing studies and psychometric validations of related questionnaires in Spanish, Danish, Russian, and Swahili.

His doctoral research focuses on a discourse analytical study of ageism in political speech within the Chilean parliament.

Research topic: Discursive psychological study of ageism in political discourse

In his doctoral research, Manuel is studying ageism against older people in public, political discussions about later life issues. He is analysing Chilean parliamentary debates and newspaper argumentative texts. Manuel aims to describe the subtle forms in which political speakers compose ageist discourse employing cultural resources (e.g., commonplaces and discursive devices) and the rhetorical effects they achieve (e.g., transforming older people’s social worth and legitimising discriminatory practices). Manuel expects to complement existing research studying the ‘middle-ground’ between individual attitudes and structural inequalities, analysing how speakers (re)produce ageism as a societal and cultural system.

Manuel collaborates as an analyst and methodological advisor in projects about individual wellbeing in Chile, the UK, Denmark, Russia, and Swahili-speaking countries in Africa. He is also working as an analyst in studies about power and violence in everyday interactions in Chile and ideological aspects of older people's conversations about ageing.
