Hiiii,
I'm a research scholar at IIT Roorkee, specializing in Acoustics, Metamaterials, and Noise Control. My research revolves around innovative noise control solutions using advanced acoustic metamaterials, particularly Sonic Crystals. I also apply machine learning methods to optimize sound attenuation and improve acoustic designs."
"Recently, I presented my findings at Internoise 2024 in Nantes, France, where I discussed the impact of scatterer shapes on sound attenuation by local resonating sonic crystals.".

Recent Work
ML-Assisted Design of Ventilated Acoustic Metamaterials.
How can we reduce low-frequency noise without blocking air? This work combines acoustic physics, finite element simulations, machine learning, and evolutionary optimization to design broadband sonic crystals.
Can Geometry Silence Sound?
Most noise barriers rely on mass.
This research explores a fundamentally different idea—using geometry to manipulate sound waves. By carefully designing concentric acoustic resonators and optimizing their shape using Kriging surrogate models and genetic algorithms, we developed a ventilated sonic crystal capable of producing multiple tunable acoustic band gaps while maintaining airflow.
The Problem
Traditional barriers reduce noise because they are heavy and solid.
While effective, they also:
Block airflow
Reduce natural lighting
Occupy significant space
Become expensive at low frequencies
Low-frequency noise remains particularly challenging because longer wavelengths require either very large barriers or entirely different physical mechanisms.
A Different Way to Control Sound
Instead of blocking sound using mass, this research uses locally resonant sonic crystals.
Each scatterer contains three concentric C-shaped cavities.
Every cavity behaves as an acoustic resonator.
Together, these resonators interact to create multiple acoustic band gaps, preventing sound waves from propagating through specific frequency ranges while allowing air to pass freely.
The barrier is open to air—but closed to sound.

Therapy has really helped me overcome some past trauma I had been keeping under a lid for a long time. Now, I feel happier and more confident in my life, and feel like I can walk with my head held high.

Coming from a competitive sports background, the injury that ended up making me give up my career was a hard blow. With therapy, I was able to start building my identity around other things than just sport.
