About
Biography
I am currently a Research Fellow working on the EPSRC funded Scalable Room Acoustics Modeling Project (SCReAM). I received my PhD degree from the Center For Computer Research in Music and Acoustics (CCRMA) at Stanford University in 2021. I graduated from Jadavpur University, Kolkata, India in 2016 where I attained my Bachelor's degree in Instrumentation and Electronics Engineering.
My primary research area is Audio Signal Processing, in particular - Room Acoustics Modeling, Statistical Estimation and Spectral Modeling of musical instruments.
Areas of specialism
Audio Signal Processing; Room Acoustics
