About me

At IIT Kanpur, my research is centred on advancing the theory and development of wireless and cellular communication systems. We utilise a unique combination of theory and practical development of wireless systems to tackle the pressing problems in this domain. We work closely with various govt organisations, industry and R&D groups to accomplish this.

Praise from honorable PM

For our efforts in designing indigenous 5G network. [Mann Ki Baat Oct 2022]

For our 5G testbed and standardization work. [IITK 2021 Convocation]

Students

Actively Looking for motivated PhD, Masters and BTech students to work with me on cutting-edge problems in 5G+/6G wireless systems.

[Current Interests] Design, analyze and optimize 5G+ and 6G wireless systems by applying machine/deep learning techniques, and optimization methods
- Please check my research interests, papers, projects and talks for specific topics.

[Current Interests] Performing standard specific research – currently leading a govt-funded project to generate IPR and take those IPRs as contributions to 5G+/6G standard

[Current Interests] Building wireless systems to evaluate their realistic performance – recently designed the first indigenous 5G network.
- Built remote radio head and baseband unit hardware from scratch.
- Indigenous 5G network was showcased in UP Global Investor and G20 Summit in Lucknow Photo1
Interested students can contact me by email with their resume.
