Umakant Kulkarni

I am a Research Scientist in the Mobile Network Systems Department at Nokia Bell Labs. I graduated with a Ph.D. in Computer Science from Purdue University, advised by Prof. Sonia Fahmy at PurNet Lab. My dissertation developed operator-centric strategies to enhance performance and reliability of cloud-native 5G core and Wi-Fi access networks.

Before joining Purdue, I worked as a Software Engineer at Microsoft, focusing on software development, architecture designing and building automation infrastructure for Affirmed Networks’ cloud-native 5G mobile core solution. Prior to that, I completed my master’s in Computer Systems Networking & Telecommunications from Northeastern University, Boston, MA, USA.

Research

My research sits at the intersection of cellular networks, distributed systems, and network security with a focus on integrating modern AI-driven techniques into operator networks. I build practical methods for configuration, resource management, orchestration, and elastic scaling to improve the performance and reliability of cloud-native mobile core systems. I am especially interested in how learning-based approaches, including LLMs and other ML techniques, can make cellular networks more efficient, robust, and easier to operate at scale.
