Mainak Chakraborty _
I am a doctoral researcher at SENSE, IIT Delhi, specializing in Cross-Modal Gait Identification and behavioral sensing. Working with Prof. Subrat Kar, I develop ubiquitous recognition systems using structural vibration and vision.
My background spans Cyber-Physical Systems, Edge AI, Signal Processing, Robtics and Practical Deep Learning. I have architected predictive maintenance systems for startups, Elephant Monitoring Devices for wildlife monitoring and hold multiple patents in sensing.
