NEWS: I have transferred to University of Washington, Seattle in September 2017 for my PhD in Computer Science and Engineering at the Paul G. Allen School of Computer Science and Engineering.


I completed two years of PhD in Computer Science at the University of Maryland, College Park. I worked in the awesome Human Computer Interaction Lab (HCIL), in particular, the Makeability Lab and my advisor was Prof. Jon Froehlich. My research interests are in the intersection of ubiquitous computing and HCI and their application in domains such as sustainability and accessibility. As my PhD work, I am working on Project Sidewalk.

Previously, 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 ubiquitous computing and human computer interaction (HCI). I am interested in studying human behavior with technology to build efficient user-centric systems. I am also interested in exploring how humans and their behavior influence the design of ubiquitous computing systems. I focus on developing technologies that have a social impact to solve high value social problems. My other interests include smart spaces, sustainability, accessibility, context aware computing, technology for development, data analytics, and machine learning. In the past, I have worked in wireless networks.

Ongoing Research Project

Project Sidewalk: Crowd Powered Street Level Accessibility
Advisor: Jon Froehlich (UMD) (August 2016 - present)
Accessible cities are primary 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 information about cities.

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 is 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. Website: EnergyLens+ project and the eco-feedback app.

Personal Activity Monitoring in Shared Spaces
Advisor: Amarjeet Singh (IIIT-Delhi)(March 2014 - October 2014)
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
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
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.
