About Me

Who I Am

I am a Post-Doctoral Fellow at the Department of Computational and Data Sciences, Indian Institute of Science (IISc). My work involves exploring the vulnerabilities in federated learning, and also designing efficient frameworks for distributed machine learning.

Research Vision

I envision a future of machine learning where collaboration does not come at the cost of privacy. My research aims to build robust, efficient, and secure AI systems that can be deployed in sensitive domains such as healthcare and finance without compromising on performance.

Current Interests

Federated Learning

  • Adaptive aggregation
  • Personalization
  • Privacy

Representation Learning

  • SSL
  • Contrastive Learning
  • Foundation Models

Medical AI

  • Segmentation
  • Diagnosis
  • Image Analysis

AI Security

  • Gradient inversion
  • Prompt attacks

Long-Term Goals

I aim to establish universally accessible, trustworthy frameworks. My ambition is to deploy scalable AI solutions, bridging the gap between advanced machine learning research and practical real world problems.

Collaboration Interests

I am actively seeking partnerships with both academic researchers and industry professionals. Particularly interested in projects involving federated learning algorithms, and self-supervised learning, and medical AI too.
