Aadesh Madnaik

PhD researcher in Electrical and Computer Engineering at Georgia Tech.

I am a PhD student in the School of Electrical and Computer Engineering at Georgia Tech and a member of the MĀRGA research group, directed by Prof. Karthikeyan Sundaresan.

My work sits at the intersection of wireless networks and sensing. I build systems that pair algorithms with robust guarantees and hardware prototypes that make those ideas practical.

Previously, I earned my Bachelor’s degree with honours in Electrical Engineering from IIT Bombay, where my thesis explored online decision-making for edge computing.

PRISM frequency-shifting RIS sensing scenario

ACM MobiHoc 2025

Practical Design and Orchestration of Frequency-Shifting RIS for NLoS mmWave Sensing

mmWave radar powers next-generation sensing in ISAC systems but struggles in non-line-of-sight environments. PRISM breaks through these limits, using RIS-based spatial modulation to turn angular cues into frequency shifts—boosting resolution without heavy computation or tight synchronization. The result: faster, more adaptable radar sensing that works...

Scalable Network Tomography for Dynamic Spectrum Access

NeTo-X is a scalable network tomography framework that maps interference patterns and estimates joint client access statistics with only linear overhead—paving the way for more efficient dynamic spectrum access in future networks. By exploiting multi-channel diversity and the spatial locality of interference, NeTo-X accurately infers...

Renting Edge Computing Resources for Service Hosting

This paper is about Better-Late-Than-Never (BLTN), an online algorithm which decides the state of an edge computing server based on historic request arrival rates. In this work, we propose a deterministic online policy and characterize its performance for adversarial and stochastic request arrival processes. We...
