Georgi Medvedev recieved Ph.D. in Mathematics from Boston University in 1999. Before coming to Drexel University in 2002, he was a Veblen Research Instructor at Princeton University and at the Institute for Advanced Study.
Dr. Medvedev teaches courses at all levels. He developed an interdisciplinary graduate course MATH 723 Mathematical Neuroscience.
He serves on the editorial board of Discrete and Continous Dynamical Systems (Series B) .
MATH 680: ST Dynamical Systems II
Dr. Medvedev's research interests include dynamical systems, network science, and mathematical biology. He is interested in combinatorial and stochastic aspects of network dynamics and synchronization; effects of noise on dynamics of nonlinear systems; and applications to neuroscience .
Dr. Medvedev's research is sponsored by National Science Foundation Award #1109367
