What I'm looking for

I'm looking to improve AI models through high-quality training data, accuracy assessment, and reliable, detail-oriented collaboration, particularly where AI, data analysis, and healthcare research intersect.

I improve healthcare AI through high-quality training data, accuracy assessment, and reliability-focused research. My work combines data annotation, large language model training, data analysis, and health sciences.

At Universidade Federal de Pelotas, I'm a doctoral researcher studying artificial intelligence in health and applying an epidemiological questionnaire with Brazilian adults and older people. My research includes adapting and validating a questionnaire on perceptions of AI in healthcare.

I've also contributed to food-policy and sociology research at the Federal University of Rio Grande do Sul, nutrition internships in oncology and primary care, and school-feeding initiatives at CECANE. I'm fluent in Portuguese and English, work comfortably across cultures and languages, and bring careful, confidential collaboration to large-scale workloads.
