About Professor Ahmed


Dr. Ahmed is an Assistant Professor in the Department of Nanoscience at the University of North Carolina, Greensboro. Prior to joining JSNN, Suzanne was a Postdoctoral Research Fellow at Harvard University. She received her Ph.D. in Chemistry from Penn State University, her M.S. from the University of California, Berkeley, and her B.Sc. from the University of California, Riverside. Her research focuses on the study of propulsion, control, and application of low Reynolds number active matter systems.


My research program focuses on the development of low Reynolds number, biomimetic, active matter. Nanoscale and microscale active matter systems commonly referred to as nanomotors, nanomachines, or nanorobots, have garnered considerable attention both for the fundamental understanding gained in inducing their propulsion and for their applications. These systems have wide-ranging applications in biomedicine, sensing, environmental remediation, and oil recovery. Our work focuses on designing and fabricating adaptive bioinspired active matter, developing novel propulsion strategies, and understanding motion within patterned and confined spaces.
