Research Interests

Mathematical modeling of cellular and tissue electrophysiology. Analysis of data from experimental and clinical arrhythmias using techniques of nonlinear dynamics (“chaos theory”). Development of pharmacologic and electrophysiologic interventions to prevent or control arrhythmias. Pattern formation in biological systems.


Dr. Garfinkel graduated from Cornell and received his PhD from Harvard in philosophy and mathematics. He is particularly interested in nonlinear dynamics and its applications to medicine.
