About

I received the MSc. in Bioengineering - Biomedical Engineering,  from the Faculty of Engineering of University of Porto (FEUP), Portugal, in March, 2016.

Early in my undergraduate years, I interned at National Institute of Biomedical Engineering (INEB), contributing in the NeurOn project - a project founded by FCT to conceive a new approach for regeneration and functional recovery of spinal cord injury. Here, I discovered my interest of promoting research through the use image analysis as a tool to obtain results in a faster, more reliable and less subjective way.

The leapt for medical image analysis came with the opportunity to join the Breast Cancer Survey (BCS) project, a project in a consortium of FEUP, Coimbra University (UC), Portuguese League Against Cancer (LPCC) and Emílio Azevedo Campos.SA (EAC.SA),  which aimed at developing automatic modules of screening and diagnosis of breast cancer to be implemented on PACS.

Currently, I am a PhD student in the informatics joint programme MAPi, a member of Visual Computing and Machine Learning (VCMI) and Breast Research Groups at INESC TEC, and a collaborator in the project BCCT.plan.

My main research interests are image analysis, machine learning and decision support systems, particularly in the area of breast cancer.

Abstract
The creation of 3D complete models of the woman breast that aggregate radiological and surface information is a crucial step for the development of surgery planning tools in the context of breast cancer. This requires the registration of interior and surface data of the breast, which has to recover large breast deformations caused by the different poses of the patient during data acquisition and has to deal with the lack of landmarks between both modalities, apart from the nipple. In this paper, the registration of Magnetic Resonance Imaging exams and 3D surface data reconstructed from Kinect (TM) acquisitions is explored using a biomechanical modelling of breast pose transformations combined with a free form deformation to finely match the data. The results are promising, with an average euclidean distance between the matched data of 0.81 +/- 0.09 mm being achieved.

Abstract
Breast cancer is one of the most common malignanciesaffecting women worldwide. However, despite its incidence trends have increased, the mortality rate has significantly decreased. The primary concern in any cancer treatment is the oncological outcome but, in the case of breast cancer, the surgery aesthetic result has become an important quality indicator for breast cancer patients. In this sense, an adequate surgical planning and prediction tool would empower the patient regarding the treatment decision process, enabling a better communication between the surgeon and the patient and a better understanding of the impact of each surgical option. To develop such tool, it is necessary to create complete 3D model of the breast, integrating both inner and outer breast data. In this review, we thoroughly explore and review the major existing works that address, directly or not, the technical challenges involved in the development of a 3D software planning tool in the field of breast conserving surgery. © 2018 by Begell House, Inc.

Abstract
INTRODUCTION AND OBJECTIVES. The knowledge and skills that enable pregnant women to adopt healthy lifestyles is broad and complex. In addition to factual knowledge, the adoption of health behaviours also implies a set of emotional, cognitive and behavioural skills that allow the use of this knowledge in the context of pregnancy. METHODOLOGY. Cross-sectional, quantitative, descriptive-correlational study with non-probabilistic, intentional sample by convenience (n = 404 pregnant women) with a mean age of 32 years. They answered the sociodemographic, obstetrical and HLS-EU-PT questionnaire (National School of Public Health, 2014). Following the methodology used in the European Survey, four ways of dealing with relevant health information were recognized. RESULTS AND DISCUSSION. Overall, 36.9% of pregnant women presented a problematic level of health literacy, 40.1%, 39.9% and 38.4%, a sufficient level of health literacy in the area of Health Care, Disease Prevention and Health Promotion, respectively. The factorial analysis demonstrates the validity of its framework. The alpha values of the items are above 0.9.The correlations between the different domains and the overall value are all positive and above 0.8. All dimensions of the scale correlate with each other in a statistically significant way, with values for the different domains. The split-half coefficient was alpha = 0.939 in the first half and alpha = 0.930 in the second half. CONCLUSIONS. The results of the present study support the psychometric adequacy of the European Questionnaire on Health Literacy - (HLS-EU-PT) for the population of pregnant women, indicating that it could be used in future trials.
