Research Interests

Dr. Spector's lab focuses on atrial fibrillation.  The work is largely along two parallel lines of investigation:  wave dynamics in multi-wavelet re-entry, and mapping and ablation of AF.  This work has resulted in 9 U.S. patent applications and the formation of an educational and R&D software company called "VisibleEP."
