I am an Assistant Professor of Computer Science and Engineering at the Indian Institute of Technology Indore. I graduated with a Ph.D. in CSE from the Indian Institute of Technology Bombay in 2020, advised by Prof. Ashwin Gumaste. My Ph.D. research was focused on various modeling, experimentation, and analytical aspects of network management in next-generation software-defined networks.

I am currently focused on developing network infrastructure for the efficient training and inference of deep neural networks (DNNs), including the complex requirements of large language models (LLMs). I am also working on designing self-optimized and highly-available next-generation networks. I am looking for motivated students to join my research group. Please send me your CV if you are interested in doing a PhD in my research interests.
