Alexander Zestos is a Visiting Researcher in the Microsystems and Nanotechnology Division and currently an Assistant Professor of Chemistry at American University with a joint appointment in the Center for Behavioral Neuroscience. He is an interdisciplinary bioanalytical neurochemist that uses voltammetry and liquid chromatography mass spectrometry to measure neurotransmitter levels. He has published several articles in top journals including Nature publishing group and the American Chemical Society. His laboratory develops carbon and metal microelectrodes to enhance neurochemical detection with fast scan cyclic voltammetry. He has many collaborations including with neuroscientists and biologists where he studies neurochemical dynamics in zebrafish, mice, and rat models. This work has vast implications for neuroscience including studying drugs of abuse, diabetes, and other diseases.
