Project Title

Fine Spatio-temporal Variation in Intra-urban Heat Stress in U.S. Cities

Certificate(s): Engineering Biology, Statistics and Machine Learning

The Urban Nexus Lab aims to advance sustainable, healthy and equitable cities through knowledge co-production and nexus modeling of key transboundary infrastructure and food systems. I worked on a project to examine intra-urban heat stress patterns in various U.S. cities. I created a data download tool to access temperature and humidity data from PurpleAir, a crowdsourced sensor network that collects air quality data. I also worked on analyzing and creating visualizations for the PurpleAir data to help us determine the viability of PurpleAir sensors to measure fine-scale intra-urban temperature variation. I’m grateful I had the opportunity to learn from the outstanding professors and graduate students at the Urban Nexus Lab and I hope to continue researching urban sustainability in the future.
