She is also a collaborating researcher at the Research Center in Sports, Physical Education, Exercise and Health (CIDEFES), Lusófona University, and at the Self-Regulation in Physical Activity, Nutrition and Obesity (PANO-SR) Research Group, Faculty of Human Kinetics, University of Lisbon. She has developed expertise in the area of self-regulation of weight loss maintenance and energy balance-related behaviours (physical activity and eating habits/behaviours) and has been involved in the design and implementation of health behavior change interventions (with individuals with overweight/obesity). Additionally, her work has contributed to a better understanding of the epidemiology of weight loss attempts in adults across the world. She published 44 peer-reviewed articles, 3 in special issues, 2 book chapters, and contributed to several abstracts/presentations in scientific conferences - Scopus h-index of 13. She is ad hoc reviewer for several leading international journals in her field. Currently, she is the coordinator of the Portuguese Weight Control Registry (PTDC/DES/72317/2006, 2008-2011), an ongoing voluntary registry of Portuguese successful weight loss maintainers, and a collaborating partner of the International Weight Control Registry, a multi-center research project developed to study individuals who succeeded in long-term weight management across the world. She is also a researcher in the Stand Up for Healthy Aging (SUFHA) randomised controlled trial and a collaborating researcher in the projects "Multidimensional cartography of breast cancer microenvironment: identification of novel therapeutic targets and biomarkers predicting clinical outcome" (iMM-Laço HUB) and "Improving colorectal cancer early screening in Portugal: Identification and validation of gut microbiome and methylation biomarkers" (iMM-Care). In the past, she was the operations coordinator of the NoHoW trial in Portugal (NoHoW: Evidence-based ICT Tools for Weight Loss Maintenance, European Commission:H2020-PHC-2014 SEP-210140063), a multi-centre 2x2 factorial randomised controlled trial investigating an evidence-based digital toolkit for weight loss maintenance in European adults, and participated in other European and FCT-funded projects. Alongside her research activities, she supervises Master and PhD students and is an external reviewer for the Evaluation Committee of the Master's Degree in Clinical Nutrition (Faculty of Medicine, University of Lisbon). In 2017 she was awarded with the Young Nutritionist Merit Award from the Portuguese Order of Nutritionists.
