About Me

I completed my Bachelors in Electrical Engineering and Computer Science from MIT in 2015, followed by an M.Eng. from MIT in 2016. While I have worked in a variety of disciplines in the past, my current research interests lie at the intersection of signal processing, machine learning, embedded systems, audio, and music. I am presently pursuing a PhD under the mentorship of Professor Joe Paradiso in the MIT Media Lab's Responsive Environments group, where I am exploring ways to capitalize on our knowledge of human perception, cognition, memory, and attention to re-think traditional paradigms for audio capture, representation, and retrieval. I am currently supported by the National Science Foundation Graduate Research Fellowship. When I'm not in the lab, I enjoy singing, playing instruments, writing, composing, and DJ-ing at MIT's college radio station.

Below are snapshots of various projects I have worked on, both as a part of my research and otherwise. Check them out!

Towards Perceptual Loss Metrics

Fall 2018

Error metrics used for training generative audio networks, typically l1 or l2 norms, do not take psychoacoustics into account. We present early ideas for designing more perceptually relevant loss metrics for deep neural networks.

Cognition-inspired Compression

Fall 2017

Instead of capitalizing on redundancies, what if audio compression schemes were modeled after human auditory attention, memory, and recall? Stay tuned for more details! Publication(s) pending. David Ramsay and I have been awarded the AI Grant Fellowship for continued work on this.

Wearable Navigation Board

My Master's research completed in the Energy Efficient Circuits group under Prof. Anantha Chandrakasan entailed running a set of signal processing algorithms to reduce system power for this platform, and implementing the algorithms for an FPGA in Bluespec. My thesis can be found here, as well as a summary of the system here on page 23.

Self-folding Robotics

A year-long research project, conducted as part of the 2013-2014 SuperUROP program, was based on the notion that robots might one day have the capacity to assemble themselves. The research focused on the design and application of origami-inspired crease patterns on a two-dimensional surface that could be transformed into a three-dimensional structure with the application of heat. A talk on the research was awarded first place at the EECS Undergraduate Research Conference (EECSCon) in 2014.

ResQ Fluid Warmer

Fall 2014 - Spring 2015

ResQ is a project initiative designed to create lightweight, portable, and non-electrically powered biological fluid warmers for use in cases of military trauma. The project, conceived by Prof. Michael Yaffe and developed jointly with Anisha Gururaj'15, Felicia Hsu'15, and David Bian'15, has been an on-going initiative for about two years. The project was most recently awarded 2nd place at the Soldier Design Competition in 2014.

Assistive Technology Club & Hackathon

In my last few years here 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! And we haven't looked back since. With the completion of ATHack 2018, the hack is now in its 6th year. 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.

Professor Teller. We continue to be inspired by you and all that you have done. We hope to carry your vision on the AT front forward in the years to come. Thank you, for everything.

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, such as Bhajans and Qawwalis, and will gladly drop anything to join in on jam sessions 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). My favorite class of instruments to play, however, has always been percussion. My freshman year at MIT, I also joined a South Asian fusion a capella group known as the MIT Ohms, and have had the chance to experiment with arranging music, directing the group, and collaborating on studio recordings. Finally, I've recently tried my hand at a bit of songwriting and have dabbled more in it after encouragement from some of my professors at MIT.

Some recent performances and recordings across genres: Krishnashtami 2016, SSE Alumni Musical 2016, Sruthi Laya TCD 2015, MIT C-Show 2016 ,Saiyyan, Someone Like You (Arr.), Sangeet Sagar 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 recent writing was awarded one of MIT's Ilona Karmel prizes, and I've written a few plays that have aired on my WMBR production, "The Daydream Company."

Some recent prose, poems, and scripts: To Be Uploaded Soon!
