    I lead a group at Janelia Research Campus. I apply methods from physics to the study of complex biological systems. To read more about the problems that I work on, check out the links above.

Dynamics of pulse-coupled oscillators with delay, organized in a ring topology. The amplitude of each node trajectory increases monotonically in time (represented here in the radial direction, and re-emphasized with both a color and size gradient), until it passes some threshold and resets. Each reset node sends a pulse (with delay) to any connected nodes, which increases the amplitude of connected nodes by some discrete step.

Graphical representation of anatomical connections in the human brain, added in order of decreasing functional connectivity (and color-coded accordingly, with orange/yellow representing strong functional connectivity and black/red representing weak functional connectivity, consistent with Hermundstad et al. PNAS 2013). Connections are represented as straight, rather than curvilinear, pathways.
