- Developed Deep/Machine Learning segmentation for ischemic and hemorrhagic stroke lesions and several head tissues in CT (Python, MATLAB, PyTorch, MONAI, etc.)
- Quality-controlled and improved a CT dataset containing 500+ subjects (MATLAB, Python) • Developed a systematic literature mapping on brain lesion segmentation by analyzing more than 100 research articles and top methods from challenges
- Developed Graphical User Interface (GUI) software for dataset visual assessment, curation, and testing of my segmentation methods (C++)
- Co-applicant for a successful grant to translate my methods to low-quality African datasets • I was supervised by the Principal Developer of FSL, the most used neuroscience library • Published 2 journal articles (unrelated to the research)
Tester (Volunteer) at DeepLearning.AI (2022-01 – 2022-12)
- Tested a Machine Learning course lectured by Andrew Ng before its public release • Provided suggestions and corrections to improve his video lectures and slides
Postdoctoral Researcher at Nuffield Department of Women's & Reproductive Health (NDWRH), University of Oxford (2020-01 – 2021-12)
- Rewrote existing Image Analysis and Deep Learning code to take advantage of updated Python libraries (Tensorflow, ITK)
- Developed a data augmentation to improve segmentation in low-quality ultrasound
- Developed a GUI software for visualization, annotation, and segmentation (C++, ITK, VTK)
- Integrated existing image analysis and deep learning tools into the GUI software
- Quality-controlled a dataset of 300 ultrasound volumes • Published 2 journal articles (1 unrelated to the research)
Professor at Instituto Federal de Educação, Ciência e Tecnologia do Maranhão (IFMA) (2019-01 – 2019-12)

- I was selected for this position in a national public contest
Research Fellow at Tecgraf Institute, Pontifical Catholic University of Rio de Janeiro (PUC-Rio) (2014-01 – 2018-12)
- Developed Deep Learning segmentation of white matter hyperintensities (WMH) in MRI (Python, Tensorflow, C++, ITK)
- Research proposed by the vice-president of DASA, the largest medical diagnostics company in Latin America
- Developed GUI software to annotate WMHs in 500+ volumes (C++, ITK, VTK)
- Pioneered the transition of Tecgraf to Deep Learning research through presentations and mentoring students
- Mentored 4 doctoral students and developed key components of their research projects, resulting in journal articles, sponsored projects, one award, and one state-of-the-art
- Published 7 peer-reviewed articles
Research Fellow at LabPAI, Applied Computing Group (NCA), Federal University of Maranhão (UFMA) (2009-01 – 2014-12)
- Main developer of SAIM, the most complex and feature-rich medical imaging software developed in Brazil
- SAIM focused on lung CT and mammography and included a large variety of visualization, segmentation, and measurement tools, including automatic lesion segmentation and cancer classification (C++, ITK, VTK, LibSVM, etc.)
- Led 3 students in a research project to detect nodules in breast thermal images (using FLIR thermal cameras) using neural networks. We also developed GUI software for annotation (C++, OpenCV, wxWidgets)
- Acted as a senior image analysis developer at LabPAI and developed many other medical research projects, and mentored and trained several co-workers
