Dr. Baer received his PhD in mathematics from the University of Illinois at Chicago. His thesis research was on the bifurcation analysis of neuron models applied to a model of a dendrite with an active soma, and the bifurcation analysis of singular Hopf bifurcations applied to relaxation oscillators in nerve. He ompleted his postdoctoral research training in the Mathematical Research Branch at the National Institutes of Health, where his main focus of research was on a continuum model for dendritic spines. At NIH he also worked on slow passage problems with application to membrane accommodation in nerves. At Arizona State University Dr. Baer has developed and analyzed models for activity-dependent spines, parabolic and elliptic bursting, neural circuitry in the outer plexiform layer of the retina, and neuromuscular junctions.
