Ishwarya Ananthabhotla
Machine Learning and Audio Research Scientist, Musician and Audio Enthusiast.
About Me
I am currently a Research Scientist on the Meta Reality Labs Research Audio Team. At present, I work on machine learning applied to problems in room acoustics, spatial audio, auditory perception, and behavior and communication understanding in conversations. More generally, my research interests lie at the intersection of machine learning, signal processing, cognition, and audio.
I completed my Bachelors in Electrical Engineering and Computer Science from MIT in 2015, my M.Eng. from MIT in 2016, and my PhD from Prof. Joe Paradiso's Responsive Environments group at the MIT Media Lab in 2021. My dissertation work entailed exploring methods to build statistical models of how our brains interact with the sounds around us, and translating these models to the auditory interfaces of the future to facilitate more meaningful, compelling experiences. I was supported by the NSF Graduate Research Fellowship from 2016-2019, and was supported by the 2020 Apple AI/ ML Fellowship through the end of my PhD. Outside of research, I enjoy singing, playing instruments, and writing; while at MIT, I also enjoyed DJ-ing at the WMBR radio station.

Music & Writing
Music
Music is perhaps my biggest passion. I've been learning and singing Carnatic music since I was five or six years old, and I have always been captivated by the artform's expressive nature and lyrical beauty. It has provided me with a sense of comfort, an avenue of relaxation, and a bridge into a past rich with culture, tradition, and faith. I also enjoy singing lighter forms of classical music, and enjoy jamming with friends and family. Over the years, I've learned to play a variety of instruments including the piano, violin, harmonium, and naal (a cousin of the tabla). I also enjoy dabbling in song writing, music production, and mixing and mastering in my spare time.
Some performances and recordings across genres: Sruthi Laya TCD 2014, MIT C-Show 2016, Someone Like You (Arr.) 2015
Writing
Many of my friends know me as perpetually having my head buried in a journal, scribbling down some thought or other. I've loved writing short stories and poetry since I was in elementary school, and after taking several fantastic creative writing classes here at MIT, I've had the opportunity to refine my writings and grow as an author. Some of my writing was awarded an MIT Karmel Prize, and I've written a few plays that have aired on my WMBR production, "The Daydream Company."
Assistive Technology Club & Hackathon
In my last few years at MIT, Assistive Technologies is a space that has become particularly close to my heart. After being inspired by Professor Seth Teller and his incredible class on designing AT (6.811), I worked closely with a team of students to organize ATHack 2014, MIT's first Assistive Technologies Hackathon! Since then, I have been involved with nine instances of the hackathon, which has continued on as an annual MIT event. The aim of both the class and the hackathon is to bring together "co-designers" in the community who live with disabilities and student engineers to work towards innovative solutions.
