Prof. Dr. Alexander George Zestos completed his B.S./M.S. in chemistry at the College of William and Mary, his PhD in chemistry at the University of Virginia, and was a postdoctoral research fellow at the University of Michigan. He is an associate professor at the College of Arts & Sciences, American University. He is an analytical chemist who uses carbon-fiber microelectrodes to detect neurotransmitters and biologically relevant molecules using fast-scan cyclic voltammetry. His research interest focuses on constructing superior electrochemical sensors through novel nanomaterials. He also utilizes liquid chromatography–mass spectrometry to detect neurotransmitters with microdialysis, the many applications of which include neuroscience, pharmacology, and drug abuse studies.
