Eligible to supervise Masters and PhD (as Co-Supervisor) - email supervisor to discuss availability.


I trained in Cardiology from the internationally recognized All India Institute of Medical Sciences, India prior to undertaking a PhD at the University of Adelaide and 4-year Electrophysiology and Pacing Fellowship at the Royal Adelaide Hospital. I am currently employed in the position of Senior Lecturer and NHMRC and NHF Health Professional Fellow within the Centre of Heart Rhythm Disorders at The University of Adelaide and the South Australian Health and Medical Research Institute (SAHMRI). I also participate in the provision of clinical (inpatient, outpatient and procedural) care for patients at the Lyell McEwin and Royal Adelaide Hospitals. I have been awarded the Health Professional Research Fellowship funded jointly by the National Health and Medical Research Council and National Heart Foundation (2016) to further my career as a clinical academic.

I was awarded my PhD from the University of Adelaide in 2014. For my PhD I was awarded several accolades including the Ralph Reader Young Investigator Award from the Cardiac Society of Australia and New Zealand (2013), first prize for the Heart Rhythm Society Young Investigator Award (2013), Best Abstract Award (2013) from the Asia-Pacific Heart Rhythm Society and the Eric Prystowsky Clinical Research Award (2015) by the Heart Rhythm Society. In addition, my thesis received a Dean’s commendation and the University Medal. The work from my PhD has been instrumental in understanding the mechanistic link between obesity and atrial fibrillation (AF). In addition, my work has challenged the long-held belief that atrial fibrosis is irreversible. My PhD studies have shown that atrial fibrosis is reversible at early stages. This change in thinking has produced new opportunity to investigate and arrest atrial fibrosis and AF. In addition, I have been involved in translating this work into the clinic and have contributed to the work from our centre on the role of weight reduction on AF burden and ablation outcomes which has been incorporated in the recent AF guidelines (ESC 2016). I am currently investigating catheter technology to improve the outcomes of ablation for atrial fibrillation.

I have established a clinical and research Cardiac Electrophysiology program at Lyell McEwin Hospital. I have served as a Consultant Cardiologist and Electrophysiologist at the Royal Adelaide Hospital through an access appointment since July 2015. I am involved in clinical training and mentoring of Clinical Electrophysiology and Pacing fellows and Cardiology Registrars at the Royal Adelaide and Lyell McEwin Hospitals.
As an Early Career Scientist within the Centre for Heart Rhythm Disorders, I am responsible for the coordination of the Postgraduate program Centre and supervision of Honours and Doctoral students with the group. Currently I am co-supervising 3 Doctoral and one Masters students. I have also been supervising the Arrhythmia rotation of twenty Y4/5 MSA medical students annually for the University of Adelaide since 2016. I am also participating in several clinical trials as principal or co-investigator for our site.
I have co-authored chapters in important Cardiac electrophysiology textbooks including Cardiac Electrophysiology: From Cell to Bedside, Zipes DP (Ed). I have over 90 publications in peer reviewed journals. I have co-authored the guidelines (2016) for advanced sub-speciality training in Cardiac Implantable Electronic devices (CIEDS) on behalf of the Heart Rhythm Council of the CSANZ and position statement on arrhythmias in endocrine disorders on behalf of European Cardiac Society.

Obesity and AF: My initial research has focussed on the risk factors for atrial fibrillation (in particular obesity). I have undertaken key translational and clinical studies that have produced new information on the mechanism by which obesity predisposes to AF and how its management results in improvement in clinical outcomes. These have been incorporated in national and international AF guidelines.

Subclinical AF and cognitive impairment: My recent focus has been on the impact of subclinical AF on stroke and have published a well cited meta-analysis on the association. I am investigating the association of AF and dementia and evaluating the role in AF screening and whether treatment of subclinical AF may have an impact on dementia in the community.

AF ablation: As a clinician, I have interest in refining the technique of AF ablation and determining the mechanisms of re-entrant atrial arrhythmias in patients after AF ablation. More recently, we have published the characteristics of the circuit of a localised atrial re-entrant tachycardia. This work was done during my 1 month stay in Bordeaux in 2017. This work has received lot of attention and was presented for the young investigator award at the scientific sessions of HRS 2018 and now published. I am also co-supervising a PhD student on the technique of single ring isolation  for pulmonary vein isolation during AF ablation.

Sudden Cardiac death (SCD): We have recently published on the association of Mitral Valve Prolapse and SCD. I am also investigating the association of morbid obesity and sudden cardiac death (SCD). I have co-supervised a PhD student who has produced new information on the mechanistic link between obesity and SCD. The work was presented and won the 1st prize for the young investigator award at EHRA 2017.

 
Research Projects Available

Research Project 1 - Subclinical AF and Cognitive Impairment

Project description: Dementia the second leading cause of burden of disease with annual expenditure of 14 billion dollars. Atrial fibrillation (AF), a common heart rhythm problem increases dementia risk by 40%. The dementia risk may be mitigated by appropriate treatment of AF with oral anticoagulants. However, AF is asymptomatic and remains undetected (subclinical). The study explores the idea whether subclinical AF is associated with risk of dementia. If positive, it will impact our screening AF program.
