Associate Professor Sean Lal

Sean Lal is an Associate Professor (Research and Teaching) in the School of Medical Sciences in the Faculty of Medicine and Health at the University of Sydney. He is also a Consultant Cardiologist in the Department of Cardiology at Royal Prince Alfred Hospital, where he is the Director of Acute Heart Failure Services.

He has senior author publications in journals such as The European Heart Journal, Nature Communications, The Lancet Diabetes and Endocrinology, The European Journal of Heart Failure, Circulaton Heart Failure, and JACC: Basic to Translational Science. He has also authored publications in Circulation, Circulation Research, PNAS, Nature Protocols, Nature Cardiovascular Research, and JACC. He has written invited Editorials for Circulation Research, Circulation Cardiovascular Imaging, JACC Advances, and The European Journal of Heart Failure.

Sean completed his undergraduate degree in Medical Science with First Class Honours at the University of Sydney, having been awarded a full academic scholarship. He continued to a graduate Medical Degree (MBBS) and a Master of Medicine (MPhil) by research (cardioimmunobiology) at the University of Sydney, where he was awarded the Dean's Scholarship, the Medical Foundation Scholarship, and the University of Sydney Bercovici Medal. As a medical doctor, Sean completed his general and specialty training at Royal Prince Alfred Hospital. During his cardiology training, he was awarded a National Churchill Fellowship to study mechanisms of cardiac regeneration at Harvard Medical School, USA.

Sean has undertaken clinical and research training in heart failure. For his PhD in this field (the molecular basis of heart failure), he was awarded a combined National Health and Medical Research Council (NHMRC) and National Heart Foundation (NHF) Scholarship, as well as the NHMRC and Royal Australasian College of Physicians (RACP) prize for research excellence.

Following cardiology training, Sean completed a clinical and basic sciences fellowship in Boston, USA. He was awarded a National Endeavour Postgraduate Scholarship by the Australian Government to Harvard University and Massachusetts Institute of Technology (MIT), where he studied the cellular biology of cardiac regeneration in ageing and in heart failure. He also led the Attending Rounds in acute heart failure management in the Cardiac ICU at the Brigham and Women's Hospital.

Sean was appointed Lecturer in the School of Medical Sciences in 2017. He has undertaken the stepwise formal processes of academic promotion to the Associate Professor level whilst maintaining a full clinical workload (inpatient and outpatient care).

Aside from teaching clinical medicine, Sean lectures in the medical sciences. He is Course Coordinator for cardiothoracic, abdominal, pelvic, reproductive, and renal anatomy for the Sydney Medical (MD) Program.

Sean is the Director of the Sydney Heart Bank, which underpins several cardiovascular research programs nationally and internationally. It is the largest biorepository of cryopreserved human heart tissue in the world. He is the Head of the Cardiovascular Research Laboratory in the School of Medical Sciences at the Charles Perkins Centre, which focuses on basic science and translational research into the molecular pathways of human heart failure, cardiovascular ageing, and cardiac regeneration. He is also Co-Director for The Centre for Heart Failure and Diseases of the Aorta, a partnership formed by the Baird Institute, the University of Sydney, and Royal Prince Alfred Hospital to facilitate translational research in cardiovascular medicine.

Our basic and translational research focuses on the human heart. We aim to investigate the molecular basis of cardiomyopathies, cellular changes in ageing, and intrinsic mechanisms of cardiac regeneration.

We uniquely draw on tissue from The Sydney Heart Bank (SHB), which contains over 20,000 cryopreserved human cardiac samples from our collaborations with St Vincent's Hospital (Sydney), the Australian Red Cross Donor Service and Royal Prince Alfred Hospital.

We have developed an extensive tissue database and international research network with the common goal to further our understanding of human heart failure.

The Sydney Heart Bank (SHB)

Overview

In 1989, in collaboration with the late Dr. Victor Chang AO, Prof. Cris dos Remedios established the Sydney Heart Bank (SHB) at the University of Sydney to collect and store explanted human hearts for research purposes. The SHB now comprises over 18,000 human cardiac samples from explanted failing hearts and non-diseased donor hearts from patients at St Vincent's Hospital Sydney. The SHB has now expanded to prospectively procure heart, aortic, and vascular samples from patients at Royal Prince Alfred Hospital under the directorship of Sean Lal, together in collaboration with Paul Bannon and Jacky Loa.

The SHB is not-for-profit and collaborates with over 30 research laboratories within Australia and around the world. The independent external research projects are in conjunction with our own in-house projects. The research projects range from examining cardiac regeneration, contractile mechanics cellular and molecular cardiology, cardiac proteomics, vascular diseases, and aortopathies.

We gratefully thank the support of the Faculty of Medicine and Health at the University of Sydney, and the Baird Institute for Heart and Lung Research in maintaining the infrastructure, staffing, and operations of the SHB. We acknowledge the patients and staff of St. Vincent's Hospital Sydney and Royal Prince Alfred Hospital.

Application process overview

1. Lodge a request for tissue. This must include the proposal, CV and HREC approval.

2. The documents will be assessed by members of the scientific review board.

3. If approved, the SHB will generate a Material Transfer Agreement between the two institutions.
