Everything interacting with the wireless signal imprints its footprint upon the signal, which is mostly discarded as noise in communication. How can we derive knowledge of the environment from this noise and, effectively accomplish Sensing without Sensors non-invasively. Babu is primarily interested in developing novel technologies with real-world implications harvesting this concept. He has invented the concept of “Mechanical-Modulation” of RF signals, and has developed a method for deriving the Motional-Signature of the internal parts of a machine non-invasively, which is a highly useful tool for diagnosis of complex machineries. This technology has been taken up by Imperial Innovations for IP protection and commercialization.
Babu has been working for past 5-years exploring Low-Power Sensing and the Physical-Layer of Wireless-Communication. He is a curiosity driven researcher, and often navigates across the boundaries of disciplines in order to derive the in-depth unifying understanding of systems. He has been working with Prof. Julie A. McCann since Aug. 2011 as an RA on various projects namely FUSE (funded by NERC), CubeSat (funded by UK Space Ajency), ICT Labs (funded by EIT) etc. and, he is also pursuing his PhD. under her supervision. Prior to joining AESE group, Babu has graduated with a B.Tech in Information Technology from IIIT Allahabad, India in 2007.
Here is a pictorial view of his research depicting how this research could be used for soil-sensing and machine monitoring.
