Electrophysiologist & AI Medical Researcher
I am a board-certified cardiologist and cardiac electrophysiologist with dual fellowship status (FACC, FHRS), specializing in the diagnosis and treatment of complex arrhythmias.
My clinical interest extends to applying artificial intelligence to cardiac diagnostics — specifically exploring whether neural networks can extract diagnostically meaningful patterns from standard ECG data that are invisible to human clinicians.
I developed this collection of validated medical calculators and decision-support algorithms to support evidence-based clinical practice in cardiology and electrophysiology.
