About me

I ♥ technology, and am passionate about developing the tech of tomorrow.

I am a research scientist at Google, focusing on health sensing hardware. My interests lie at the intersection of sensing research and systems engineering.

Previously, I have worked at a silicon valley startup (Wisk Aero) evaluating sensing for autonomous eVTOL flights and also at an early phase startup (DeepSig) creating AI native communications stack.
As a master's student in Computer Engineering at Virginia Tech, I dabbled in neuroscience research with Prof Sujith Vijayan on Brain Computer Interface.

I also like making fun stuff with a raspberry-pi, playing the piano, going on long hikes and contributing to open source!

Work Experience

Google (Fitbit)Feb 2022 - Preset

Flying taxis. Yeah! I am equally amazed! Check them out here.
My work involves sensor integration and testing (and also designing tests, performing Data Analysis) to meet aviation requirements. I work on a novel aviation sensor solution and making sure it works the way we expect it to! My mentor usually throws a new piece of hardware on me, for testing/bringup and interfacing with aviation hardware (basically the code I write is flying high!). .

DeepSig IncMay 2018 - August 2018

Machine Learning Intern

I am working on interfacing the software suite of the company with different OpenSource tools for improving the signal processing and the machine learning workflow.
I am also working on the developement of the OmniPhy product, which is an optimised wireless channel encoder-decoder (PS. Think 6G comms)..

Neural Dynamics Lab, Virginia TechNov 2017 - May 2018

Graduate Student Researcher

I am working on developing a deep neural network for modelling the brain activity. Currently we are experimenting with different architechtures such as LSTM+RNN, Spectograms as Images and also traditional ConvNets.

I am also working on interfacing a BMI(Brain Machine Interface) using EEG and ECoG data to study the effects of sleep. I am also building different classifiers for complex BMI tasks. (Mind control. Works. Mostly.).

Mercedes Benz Research and Developement, IndiaAug 2016 - Jul 2017

Sofware Engineer

I was initially working on a navigation problem for autonomous driving in various traffic scenarios.

Later, I joined the Daimler Trucks Powertrain Diagnostics Team where I was working on ECU measurement, calibration for the Euro IV,VI and the NAFTA market. I also worked on Test Automation for Diagnostics Testing to reduce time spent in Freeze Frame Testing and ISO27145 Protocol conformance Testing.

Ishnatek SystemsJun 2018 - Aug 2016

Android Developer

I was reponsible for building and integrating data capture libraries for images, videos, QR codes and text inputs for managing health records for pets. The interface designed was aimed to user-friendly and interactive. I also worked on designing the SQLite database to manage and store the records.

.

Defense Research and Developement, IndiaJun 2015- May 2016

Embedded System Developement Intern

I worked on the challenge of simultaneous localization and mapping for an autonomous agent whose only sensor input was an Inertial Motion Unit. The project enhanced the reliablility and accuracy of a single sensor system and overcame the partial drawbacks of using accelerometers in an Inertial Navigation System.

San Telequip Pvt. Ltd., PuneJun 2014 - Nov 2014

IOT product design intern

My team worked on designing a wireless video doorbell service for accessible and portable use. I worked on Python based client-server interaction for a storing and managing the video stream data based on the doorbell input. The accessiblity was increased by developement of a Web App and an Android App.

FingerSpeller - Gesture Recognition for American Sign Languagecomputer-vision

Using histogram of oriented gradients feature along with a SVM classifier, we trained a model for gesture recognition for Finger Spelling. A predicited word output was also given using the letters predicted from this model to increase letter coverage and accuracy for real time video camera input. A Deep Learning model was also trained to perform the same task to compare the two models.
