My principal research area lies at the intersection of computer vision and medical image analysis and machine learning. I have a strong interest in self-supervised methodologies on learning from limited data or labels, which I consider major avenues for innovation and impact for many vision-based applications. The ultimate goal of my research is to build next-generation intelligent machines that will tackle many of the most challenging problems in responsible AI, including reliability, generalization, and overcoming the hurdles posed by data and annotation scarcity. My aim is to ensure that AI systems are robust and reliable enough for deployment in critical, real-world applications.
