Hello! My name is Zeal and I am a second year Ph.D. student in the Electrical & Computer Engineering department at University of Massachusetts Amherst. I work at the Systems Towards Infrastructure Measurement & Analytics (STIMA) lab, advised by Prof. Jay Taneja. I hold a master’s degree in Energy Science, Technology & Policy with concentration in ECE from Carnegie Mellon University. My research at UMass Amherst is focused on harnessing the power of data and technology for developing low-cost energy infrastructure monitoring and management solutions. Additionally, my work also involves using mobile systems, remote sensing, machine learning & deep learning for acquiring data and information in low-data settings.

GridInSight: Monitoring Electricity Using Visible Lights
Created a low-cost solution to non-intrusively monitor grid power quality and phase using smartphone cameras to facilitate better management of grids in developing countries.
- Demonstrated the use of cell phone and machine vision cameras to non-intrusively monitor electric-grid frequency and phase with errors of 1-2%, and 2-10%, respectively.
- Developed a novel technique that uses cameras to passively monitor voltage, and obtained an error of 8-15% for measuringvoltage of a light bulb that our system had not seen previously.
Smart Metering Data For Tracking Access to Electricity
- Analyzed smart meter data to track the evolution of electricity availability, reliability, quality, and grid capacity across 68sites spread over Sub-Saharan Africa and South-Asia with 10 to 500+ customers (smart meters) per site.
- Quantified the growth of energy access across sites by linking smart meter data analysis to World Bank’s Multi-tier Framework for household electricity supply.
