Hi :wave:, I’m a Senior ML Engineer in the Foundation Models and Data team at LinkedIn AI. My work centers on post-training techniques for enhancing multi-task learning in large language models. I earned my MSc in Computer Science at NYU Courant, where I worked with Prof. Joan Bruna on the Neural Collapse phenomenon. I have also contributed to TensorFlow and served as a maintainer for TensorFlow-IO during my time at IBM. I hold a B.Tech in Electronics and Communication Engineering from IIT Guwahati.

Research

I’m primarily interested in understanding the computational aspects of learning in neural networks, and using these insights to develop novel modeling techniques.

  • Foundation Models: Chain-of-Thought reasoning, In-Context Learning and Multi-Task Learning in Transformer based LLMs.
  • Learning Dynamics: Understanding feature evolution, weight matrix spectra and generalization in neural networks.
  • Efficient Training/Inference: Developing low-level (randomized) algorithms for training and inference of large scale LLMs/GNNs.
