Work Experience
Thirona
Deep Learning Engineer
•AVX - Artery Vein Segmentation Module: Contributed in the research and development of the AVX module for pulmonary hypertension research. I designed and implemented pipelines, and executed experiments to validate concepts and measure progress. Subsequently, refined biomarkers, measurements characterizing the segmented vessels, enhancing their precision and contributing to the overall advancement of the module.
•Fissure Segmentation and Classification: Contributed to improving the efficiency and inference time of the fissure segmentation module. This module identifies and classifies lobe fissures as complete or gapped. Implemented enhancements for quicker and more precise analysis, crucial for assessing collateral ventilation in patients.
Research Assistant
I conducted research on the comparison of Vision Transformers with traditional CNNs for Chest X-Rays classification. I evaluated various datasets and techniques to improve training efficiency and analyzed the impact of data augmentation on final performance.

Projects
Artery-Vein Phenotyping - AVX
I contributed to the artery-vein segmentation module by researching practical improvements. I designed and implemented parts of the pipeline, such as the training, inference and evaluation pipeline, and through literature research explored different normalization techniques, new metrics, and new loss functions to accurately segment anatomical structures, thereby obtaining predictions that conformed to our requirements. In addition, I refined the calculation of biomarkers to ensure to provide clients with highly precise and informative measurements regarding vessels.
Fissure Segmentation and Classification
Improved efficiency and reduced inference time of the fissure segmentation module. This module identifies and categorizes lobe fissures as complete or gapped. Implemented enhancements for faster and more precise analysis, critical for evaluating collateral ventilation in patients. Additionally, introduced evidential deep learning to estimate confidence and uncertainty in model predictions.
Multi-modal Chest X-Ray analysis using self-supervised learning
I improved the downstream classification performance by performing self-supervised pre-training using BarlowTwins on unlabeled X-Rays datasets. GPT was then utilized to generate reports based on the visual features of X-rays.
Abnormal ECG classification
A project involving Recurrent and Generative Adversarial Networks for classifying abnormal heart rhythms and generating synthetic data.
