Netzahualcóyotl Arroyo Currás (Netz Arroyo) is an assistant professor in the Department of Pharmacology and Molecular Sciences at the Johns Hopkins University School of Medicine. Arroyo’s research focuses on the development of electrochemical biosensing platforms that enable continuous, real-time measurements of specific molecules in the body in both healthy and diseased states. His lab employs these sensors to study molecular transport of therapeutics across biological barriers in vivo, and to develop decentralized, high-precision diagnostics for health care monitoring. Current research efforts are focused on translating DNA aptamer-based sensors to in-human clinical use. Arroyo also has secondary appointments in the Departments of Chemical and Biomolecular Engineering, Biochemistry, Cellular and Molecular Biology, and the Chemistry-Biology Interface programs. He received his bachelors of science degree in chemistry from Tec de Monterrey (Mexico), his Ph.D. in analytical chemistry from the University of Texas at Austin, and completed his postdoctoral training in bioengineering from the University of California Santa Barbara.
