Dr. Di Biase is currently serving as the Senior Researcher at Texas Cardiac Arrhythmia Institute.  

The heart of Dr. Di Biase's mission is improving patients care and he believes that it is possible through dedicated clinical practice associated to cutting-edge clinical research.
His research is focused on cardiology and electrophysiology with a specific emphasis on catheter ablation of atrial fibrillation and ventricular arrhythmias performed either manually or with robotic catheter navigation as well as on heart failure especially treated with cardiac resynchronization therapy devices.
Dr. Di Biase is a 2000 graduate (Summa Cum Laude) from the Medical School at the University of  Bari, in Italy.  In 2004, he completed a 4-year residency program in Cardiology (Summa Cum Laude) at the University of Bari Medical School.  In 2006, Dr. Di Biase completed a II Level Master certification in Electrophysiology and Pacing (Summa cum Laude) at the University of Insubria at Varese and Brescia, Italy.
In 2007, he received a grant from the Italian National Society of Cardiology to pursue a research fellowship under the supervision of Dr. Natale at the Miller Family Heart & Vascular Institute at the Cleveland Clinic, in Cleveland, Ohio. 
In July 2008, Dr. Di Biase accepted a position in Cardiac Electrophysiology at the University of Texas Medical School Branch at Galveston, Texas, where he continued to focus on his research projects under the leadership of Dr. Natale, at St. David's Medical Center.   
In 2009 he became Adjunct Professor at the University of Texas, in Austin.
