Research projects that contribute to the 17 UN SDGs are indicated using individual SDG icons.
We have made research contributions in the following areas:
I am honored to be selected BBISS Faculty Fellow, 2023
I am honored to be selected to the inaugural cohort of Energy Equity, Environmental Justice & Community Engagement Faculty Fellows, 2023
Tiny Data
Several of our projects culminate into the theme of Tiny Data.
At a high level, it is the idea that even a miniscule amount of data of the right kind can enable important applications.
A 10-minute presentation about Tiny Data is here.

Internships
NEC Labs, Summer 2018
Multilateration from moving anchors
In this work we investigate if localization can be performed even when the anchors are mobile.
It has applications in various scenarios—military troops storming an enemy building, fire-fighters putting out fire sources inside buildings, search and rescue, etc.
Resulted in the NSDI 2019 paper.
Intel Labs, Summer 2016
Tracking a game of cricket—ball and players A cricket ball embedded with UWB sensors was tracked using two anchors placed at the two wickets on a cricket field.
The ranging protocol was improved to support about 150Hz update rate.
The fast moving ball and players were tracked using a MIMO UWB device. Resulted in the NSDI 2017 paper.
Zendrive, Summer 2015
Mode of commute categorization using mobile IMU data Zendrive enables automatic rating driving quality for all drivers of taxi-fleets.
In this work, a mobile device's IMU data was used to distinguish between various modes of transportation.
This enables tracking people's activities and provide better context to Zendrive's mobile App.
Thus, a person's mountain-biking does not affect her driving record.
Avaya, 2005-2006
Outlook plugin for automatic issue tracking
Avaya's internal teams frequently send emails about product issues to each other.
The contents were eventually manually copied into an issue tracking system.
We automated this process using an Outlook plugin that detected issue related emails and offered to post the contents in the system.
This system continued to be used at Avaya for 6 years after our internship.
Work Experience

Madwifi, 2009
Enabling TDMA on the Madwifi wireless driver During our work on long-distance wireless networks, we performed significant changes to the open source
Madwifi driver to disable usual CSMA capability and instead send and receive wireless packets at exact intervals.
Most of these ideas remain applicable even in the latest Atheros drivers and the blog is a good starting point for understanding wireless buffer flow inside the driver.

Miscellaneous Experiments of a PhD Student, 2015
Titbits on wireless drivers, sensing, and ranging
Details about a project's engineering aspects sometimes do not find a place in publications.
Yet, engineering is indeed required to build full working systems that demonstrate the underlying principles.
This blog is a catch-all that attempts to bring such experiences under one roof.
