Biosketch

El-Sayed graduated from the Chemical Engineering Department at Cairo University. She had her Masters of Science degree in Chemical Engineering from the same university specifically in the field of Cleaner Production. She also had a Master of Philosophy degree in Engineering for Sustainable Development at University of Cambridge in the United Kingdom. Before starting her PhD, El-Sayed was a Research Fellow at the National Research Center of Cairo as well as an Environmental Consultant at EcoConServ Consulting. El-Sayed was a PhD candidate at the Chemical, Biochemical and Environmental Engineering Department at the University of Maryland, Baltimore County (UMBC) where she conducted research in the Air Quality & Atmospheric Chemistry at the Hennigan Lab.

During her PhD at the Chemical Engineering Department (UMBC), El-Sayed was working on an air pollution project under the supervision of Dr. Chris Hennigan which focused on characterizing and better understanding the formation of secondary organic aerosols formed in atmospheric liquid water (aqSOA) especially in the Baltimore area. She developed a real-time ambient analytical method to characterize the reversibility of aqSOA formation through simultaneous measurements of gaseous and particle (ambient and dry) water-soluble organics. In that regard, she conducted seasonal field experiments in Baltimore to characterize the aqSOA formation in successive years where she collected seasonal PM2.5 aerosol measurements in addition to performing statistical analyses for large datasets.

El-Sayed's passion for the environment has made it the central theme of her professional life. She looks for every real opportunity to contribute to people's lives in light of the multiple challenges of air quality and climate change. She is also seeking opportunities to build rapport between science and communities in a sustainable way.
