The ubiquitous trend to ''Go Wireless'' is a symbol of our need for independence and flexibility. To allow for an ''All Wireless'' world, large amount of information with widely varying content have to be exchanged with high speed, utilizing low power and low cost. Here lies the motivation for research which needs knowledge of both the systems and requirements engineering.

In her research, Debarati broadly focuses on Wireless and Optical Communication including Interdisciplinary Computing, mostly on 5G and Beyond Communications, AI enabled Wireless, Millimeter Wave and Terahertz Communications, Critical CommunicationsLarge MIMO, Cloud RAN etc. Her research is supported by a variety of Govt. Organizations including MHRD, MeitY, Min. HI&PE, BEL, HAL, DST, DRDO, SERB, Indian Railways and external collaborators like AIRBUS, Samsung, Qualcomm, Ericsson, TI, PwC, Rosenberger etc. She has 20 patents to her credit, and published more than 130 papers in Journals and Conferences of repute.

Her research style lies at the juncture of theory and practice. While much of the work tends to be mathematical in terms of tools use, the problems she solves originate from practical engineering considerations. In particular, Debarati is interested in determining the theoretical limitations of systems, and how they guide the architecture of next generation communication systems.
