My research interests span the areas of deep learning, computer vision, machine learning, medical image analysis and artificial intelligence.
In a nutshell, the goal of my research is to develop efficient, scalable and mathematically well-grounded algorithms that are capable of analyzing and extracting (semantic) information from various types of visual data (be it static natural images, video, medical image data etc.).

Excited to share our work "Online Bag-of-Visual-Words Generation for Unsupervised Representation Learning". Proposes novel approach for self-supervised learning that surpasses all previous state-of-the-art methods (including contrastive-based ones), setting new state-of-the-art results on a variety of commonly used benchmarks. Source code and trained models are available at the project page.
