About

I am a PhD CSE student at the Paul G. Allen School of Computer Science and Engineering at the University of Washington, Seattle (UW). I am a part of the Makeability Lab led by my advisor Prof. Jon Froehlich.  My research interests are at the intersection of HCI and urban informatics and their application in domains such as accessibility and sustainability. As my PhD work, I am working on Project Sidewalk, reappriopriating online street imagery to assess urban accessibility.

I was in the Computer Science department of University of Maryland, College Park (UMD) for the first two years of my PhD. At UMD, I worked in the Human Computer Interaction Lab (HCIL). Prior to joining PhD, I was a research scholar at IIIT-Delhi. I worked in the Mobile and Ubiquitous Computing (MUC) research group and was a part of Energy Research Team. My advisor at IIIT-D was Prof. Amarjeet Singh. I have also worked in collaboration with Prof. Yuvraj Agarwal (CMU) and Prof. Anind Dey (CMU) on my research.

Research Interests

My research interests are broadly in the areas of Human Computer Interaction (HCI) and Urban Informatics. I enjoy multidisciplinary application-oriented research that involves designing, developing, and evaluating systems in the real world, and that can be applied to solve high value social problems. My current and past work falls within these sub-domains: accessibility, sustainability, data visualization, ubiquitous computing, and smart spaces. I also have an interest to work in ICTD or technology for development.

Ongoing Research Projects

Interactive Visual Exploration of Physical Accessibility
Advisor: Jon Froehlich (UW) (January 2018 - present)
Collaborator: Jeffery Heer (UW)

Leading the development of an interactive system that provides an at-a-glance visualization of physical accessibility using data collected from Project Sidewalk and other city data sources. Part of this project also involves building a personalizable accessibility model that can assess and score accessibility of regions based on specific needs of mobility impaired users (e.g., manual wheelchair user vs powered wheelchair user).

Project Sidewalk: Enabling Crowd-powered Street-level Accessibility Data Collection · ·
Advisor: Jon Froehlich (UW) (August 2016 - present)
Accessible cities are essential for a truly inclusive society. This project looks into scalable methods for collecting and using accessibility data for creating useful Assistive Location-based Technologies (ALTs) to support people with mobility impairments. In particular, we are using crowdsourcing techniques to collect street level accessibility data about cities. We want to build novel applications that will aid people with mobility impairments to plan their travel and navigate efficiently in cities, and also, help other stakeholders such as city governments to determine accessibility of cities with the help of interactive visualization tools.

Past Research Projects

Exploring the Role of Thermography in Creating Novel Human-Building Interactions
Advisor: Jon Froehlich (UMD) (September 2015 - January 2017)
Collaborator: Matthew L. Mauriello (PhD Student, UMD)

In this project, we investigated the potential to engage the public in new Human-Building Interactions by expanding their ability to: perform energy audits, survey public infrastructure, and contribute to urban energy analysis.

Personal Energy Monitoring in Smart Homes · ·
Advisor: Amarjeet Singh (IIIT-Delhi) (July 2013 - July 2015)
Collaborators: Yuvraj Agarwal (CMU) and Anind Dey (CMU)

This goal of this project was to explore the use of smartphone sensors and electricity meter for inferring daily activities and identifying the individuals who performed them. The results of this study is published in the EnergyLens paper (ACM e-Energy 2014). The system architecture was evaluated for shared living spaces and a room-level energy apportionment system called WattShare (ACM BuildSys 2014) was built. It was part of the larger HumanSense Project.
I worked on building an end-to-end energy apportionment and feedback system for smart homes with an objective of providing occupants with relevant information about their personal energy consumption at the right time. It is based on the original EnergyLens system.

Personal Activity Monitoring in Shared Spaces
Advisor: Amarjeet Singh (IIIT-Delhi)(March 2014 - October 2014)
Collaborator: 
Kumar Padmanabh (Bosch Labs, Bangalore)

This project aimed to develop insights into personal activity monitoring in shared spaces, specifically in the home environment, through the use of pervasive computing technologies. In particular, we wanted to leverage the smartphone, a rich source of information, to develop insights for personal activity monitoring and feedback services for the DIY sector. The objective was to do so in the context of using power tools in home environments.

SensorAct: An Occupant-centric Middleware for Buildings
Advisor: 
Amarjeet Singh (IIIT-Delhi) (November 2012 - May 2013)
Collaborator: Mani B. Srivastava (UCLA)
As part of the Energy Team in IIIT-D, I worked on SensorAct, a middleware for building management. It interfaces with diverse building sub-systems and sensing systems; makes the data available and allows sharing of data and control with users in a secure manner keeping in mind privacy issues.

Bandwidth Management Framework for Multicasting over Wireless Mesh Networks
Advisor: 
P. V. Krishna (VIT University, Vellore)(September 2011 - May 2012)
As a Masters student, I took up an independent research project wherein I developed a bandwidth management framework for performing multicasting over wireless mesh networks. This was later converted into my Masters Project.
