Imari Walker Karega

Walker Karega

Doctoral Candidate - Civil and Environmental Engineering

Imari’s research examines how environmental factors influence the release and transformations of plastic additives into aqueous media. She investigates the relationship between carbon nanotube loading, ultraviolet light, temperature and pH on the release of Bisphenol A, a known endocrine disruptor. She also explores suspect screening and targeted analysis to identify and quantify potentially hazardous plastic additives released into water.
