Professional Summary

I am a Senior Research Specialist at Nokia Research and Innovations in France, working on beyond-5G/6G wireless communications technologies. I successfully defended my PhD in Communication Systems from Linköping University, Sweden, on November 29, 2024, with the thesis titled “Distributed Signal Processing for Cell-Free Massive MIMO”. My doctoral research was supervised by Prof. Erik G. Larsson and Prof. Emil Björnson.

My research expertise spans cell-free massive MIMO, distributed signal processing, physical layer innovations, and optimization techniques for next-generation wireless networks. I’m passionate about advancing wireless communications technology and enjoy sharing my knowledge through this blog.

To know more about my work: LinkedIn, Google Scholar. Whatever I am today is because of my lovely parents and younger brother. Follow my blog: Ride-the-Future.

📚 My Research
My work focuses on making future wireless networks smarter and more efficient. I develop distributed signal processing algorithms for cell-free massive MIMO—a technology that enables seamless connectivity by coordinating many access points to serve users without traditional cell boundaries. Think of it as teamwork for antennas, delivering better coverage and higher data rates for the connected world.
