My research spans the interdiciplinary fields of mathematical biology, cell biophysics and computational neuroscience. The main focus of my work is on mathematical and computational modeling of the mechanisms of synaptic neurotransmitter release. I am also studying the activity-dependent changes in synaptic strength called short-term synaptic plasticity, as well as the impact of such short-term synaptic dynamics on the activity and information-processing properties of neuronal networks. Related to this endeavor is the study of the intracellular calcium ion diffusion, necessary for the understanding of synaptic function and plasticity mechanisms, as well as a wealth of other important cell processes. I am especially interested in the role that the endogenous calcium buffers (intracellular molecules that bind calcium) play in regulating cell calcium signals in general, and synaptic transmission in particular. Finally, I study the impact of synaptic properties on the behavior of synaptically coupled neuronal circuits, exploring for instance network synchronization and network bursting.

Calcium Calculator Modeling Software

To study quantitatively the dynamics of calcium diffusion and buffering in the synaptic terminal, I develop a modeling program called CalC ("Calcium Calculator"). Here you will find links to the CalC download page, the CalC manual, the database of CalC simulation scripts, and a complete list of peer-reviewed publications that relied on simulation data produced using CalC.

New: CalC version 7.0 implements cooperative calcium buffers
New: CalC version 7.4 implements binary file output
New: CalC version 7.6 implements non-linear membrane pump
New: CalC version 7.7 implements spherical enclosures and obstacles
New: CalC version 7.8 allows arbitrary piece-wise smooth enclosure boundaries
New: CalC version 7.8.4 greatly improves adaptive time-step control
