Ashley Collier-Oxandale completed her PhD in Environmental Engineering at CU in 2018. She had been working with this lab since 2011. Her work focused on air quality sensor quantification and research applications. For example, one of her projects involved using a low-cost sensor network to examine the spatial variability of methane and non-methane hydrocarbons at the neighborhood scale in order to better understand potential exposures for the residents of that neighborhood. Other areas of interest include working to support community-based science and facilitate effective STEM education/outreach. Outside of the lab (in addition to of course enjoying the wonderful Colorado scenery via hiking, biking, etc...) she enjoys fancy coffee, reading, traveling, and the occasional ballet class.Â
