Dr. El-Sayed is an assistant professor in environmental engineering in the civil engineering department at Embry-Riddle Aeronautical University (ERAU). El-Sayed’s research interests lie in characterizing the processes and sources of atmospheric pollutants to better understand how human perturbs these processes to ultimately quantify their impact on climate change, policy making, and human health. She has over a dozen publications and presented her work in several national and international conferences.

El-Sayed received her PhD at University of Maryland, Baltimore County (UMBC) in Chemical, Biochemical & Environmental Engineering working on air pollution projects which focus on characterizing atmospheric aerosols particularly in the eastern United States. She holds a Masters degree from the University of Cambridge in the United Kingdom in Engineering for Sustainable Development. She received an M.Sc. and a B.Sc. degrees in Chemical Engineering with honors from Cairo University in Egypt.

Dr. El-Sayed joined Colorado State University as a postdoctoral fellow at the Atmospheric Science Department where she conducted several field studies to investigate the air quality in the western United States. Prior to her doctorate degree, El-Sayed has worked as a research fellow at the National Research Center of Cairo where she applied the concepts of cleaner production in the Egyptian industry. In addition, she worked as an environmental consultant for several projects in the Middle East and Europe.
