Orchisama Das

I am presently a second year PhD candidate at the Center For Computer Research in Music and Acoustics (CCRMA) at Stanford University, pursuing a doctorate in Computer-Based Music Theory and Acoustics. I am also a teaching assistant for the graduate course Music 320A - Introduction to Audio Signal Processing - Part 1 : Spectrum Analysis taught by Julius Smith. I graduated from Jadavpur University Kolkata, India in 2016 where I attained my Bachelor's degree in Instrumentation and Electronics Engineering. Additionally, I was a Mitacs Globalink intern at University of Calgary, Canada from May-August, 2015.

I have been passionate about music for a long time, since I started playing the guitar and later picked up the bass guitar. My love for music and technology allowed me to integrate these two fields. My research interests are Audio Signal Processing, Semantic Audio, Music Information Retrieval and more recently, Statistical Signal Processing.
