Dr Choy is a Senior Clinical Lecturer in the Centre for Cardiovascular and Diabetes Medicine and a consultant cardiologist with interests in inherited and acquired arrhythmias. She is also the lead for international medical students at the medical school. Prior to her appointment in 2004 to University of Dundee, she was an associate professor in Cardiology, and head of the Arrhythmia Service at the University of Malaya, Kuala Lumpur. She was an American Heart Association Fellow at Vanderbilt University School of Medicine where she trained in electrophysiology and was a research fellow to Professor Dan Roden. She was awarded the North American Society of Pacing and Electrophysiology Young Investigator award for her research in 1997.

Her research interests are arrhythmia related; focusing on implantable cardiac electronic devices for arrhythmia management, the familial arrhythmias, anti arrhythmic drugs and atrial fibrillation.
