Dr. Siladittya Manna

Senior Research Assistant

Research Focus

I am a passionate researcher specializing in federated learning, self-supervised learning, computer vision, and medical image analysis. Currently working as a Senior Research Assistant at Hong Kong Baptist University under the supervision of Prof. Yiu-Ming Cheung. I focus on developing innovative federated learning framework for computer vision applications in medical image analysis.

Research Interests

My research interests span self-supervised learning, federated learning, deep learning, computer vision, and medical image analysis. I am particularly interested in developing robust and interpretable AI systems that can learn meaningful representations without extensive manual annotations.

Past Experience

I completed my PhD under the supervision of Prof. Umapada Pal from Indian Statistical Institute, Kolkata. My research primarily focused on self-supervised learning and its applications in medical image analysis. I have also worked on signature verification, writer identification, other document analysis tasks. During my Ph.D. I also worked closely with Dr. Saumik Bhattacharya from Indian Institute of Technology, Kharagpur.
