This week's Change Seminar Speaker will be Dr. Yael Borofsky <https://dec.ethz.ch/people/team/yael-borofsky.html>. Dr. Borofsky's talked is titled "Solar Public Lighting & Sensors in Informal Settlements: Lessons from Research and Practice" *Description: *Informal settlements are unplanned neighborhoods where approximately 1 in 7 people worldwide live. In Cape Town, where my research is focused, nearly 14% of households live in one of the more than 400 informal settlements. The vast majority of research has focused on access to services like shared sanitation, water taps, and housing, but these studies have often ignored an important aspect of life in informal settlements: nighttime. I will discuss how my colleagues and I drew on transdisciplinary methods and used both novel and traditional data collection techniques, including light meters, pedestrian motion, and household surveys to test the impact of wall-mounted solar public lighting in an informal settlement in South Africa. In describing the project, I will also share some key lessons from both research and practice intended to promote discussion and inspire other researchers to take on transdisciplinary research methods. *Seminar Details* *Location*: Tuesdays from 12-1pm in 271 CSE2 (The Bill and Melinda Gates Center) *Zoom:* https://washington.zoom.us/j/95324763742 *Present Bio* Dr. Yael Borofsky is a Senior Scientist in the Development Economics Group, where she helps manage the research group and conducts research focused on access to infrastructure in informal urban settlements. She is a co-founder and editor of the ETH Energy Blog <https://blogs.ethz.ch/energy/>. Yael received her PhD from ETH Zurich in 2022. She has a dual masters' degree in City Planning as well as Technology and Policy from the Massachusetts Institute of Technology and a BS in Human Development from Cornell University.
