About me

My background is in academic research, mainly in clinical psychology, transgender healthcare, and research methodology. My training in psychology and philosophy of science has shaped my interest in metascience—how knowledge is produced, evaluated, and trusted—and in how scientific institutions, emerging technologies, and social actors shape that process.

In 2026, I moved into the market research industry, where I currently work as a quantitative researcher. I am especially interested in survey methodology, online research panels, data quality, and emerging developments such as synthetic data and AI-assisted research.

Two strands of work

Academic research

My work has focused on transgender healthcare, especially the experiences of people who transition, detransition, or discontinue gender-affirming care. I have also examined the available scientific evidence on these topics through systematic reviews and critical analyses of the literature.

I have worked with quantitative, qualitative, and mixed-methods approaches, collaborating with researchers and healthcare professionals in Spain and internationally. My work has appeared in high-impact journals such as Clinical Psychology Review and BMJ.

I am also co-author, with Kinnon MacKinnon, of a book titled Understanding Detransition, forthcoming with Polity.

Market research

I joined We are testers, a market research consulting agency based in Spain, as a Research Executive, moving from academic research into applied research for businesses and organizations.

My work involves designing, managing, and conducting quantitative and UX research projects, including questionnaire development, sampling, fieldwork coordination, data quality checks, statistical analysis, and final reporting.

Although the research questions and working environments have changed, I continue to draw on my academic training in research design, measurement, and statistical methods.

Books

Understanding Detransition

Kinnon R. MacKinnon and Pablo Expósito-Campos. Polity (forthcoming spring 2027).

Drawing on original research, sociology of medicine, and philosophy of science, we examine successive paradigms of transgender medicine, how the modern concept of detransition was constructed, and how the field has become a canvas for competing values.
