Professor of Public and Mental Health · Chair, Personality and Individual Differences Lab (LAPEDI)
My work examines the mechanisms linking personality, individual differences, and social determinants to mental and physical health outcomes. Combining psychometrics, epidemiological designs, and cross-national consortia, our group investigates psychological distress, stigma, developmental psychopathology, and chronic health conditions.

Academic Profile
Background, appointments & international collaboration.
UNIOESTE is the only state university in Brazil to achieve the maximum institutional grade (5/5) from the Ministry of Education (INEP/MEC, 2024).
I am a faculty member in the Department of Medical Sciences (Faculty of Medicine) and the Graduate Program in Applied Health Sciences at Western Paraná State University (UNIOESTE), where I chair the Personality and Individual Differences Lab (LAPEDI) and the Public Health Lab, and practice at the University Medical Outpatient Clinic.
I received my Ph.D. in Psychology from Goldsmiths, University of London (2018), where my doctoral work investigated callous-unemotional and psychopathic traits, emotional processing, and stress physiology. Prior to my doctorate in the United Kingdom, I completed my undergraduate and graduate training in Psychology at the Pontifical Catholic University of Rio Grande do Sul (PUCRS).
Across theoretical and applied fronts, my research relies on quantitative designs, structural equation modeling, item response theory, and cross-cultural measurement invariance. I am also actively involved in multi-country research consortia and evidence-based synthesis (systematic reviews and meta-analyses) aimed at strengthening replicability and representing non-WEIRD and structurally vulnerable populations in psychological science.
