Researcher biography

MS has 35 years clinical research experience in pathogenesis and management of hypertension (HT), including endocrine varieties such as primary aldosteronism (PA). Working within the Greenslopes Hospital Hypertension Unit (GHHU), he helped demonstrate that PA is 10 times more common than previously thought and to account for approximately 10% of HT, making it the commonest specifically treatable, potentially curable variety, and in the description of a new familial form (FH-II) which recently led to the elucidation of its genetic basis (a gain of function mutation in CLCN2, published in Nature Genetics). The combined GHHU/Princess Alexandra Hospital HT Unit (PAHHU, which MS set up in 2000) has possibly the largest series (>2500) worldwide of patients with PA who have been thoroughly documented and meticulously studied, helping MS to become internationally recognized as an authority on pathogenesis/genetics, diagnostic workup and management of PA. In 2006, MS served as member of an international Task Force sponsored by the US Endocrine Society to develop the first guideline for diagnosis and management of PA (published in J Clin Endocrinol Metab and cited >1200 times with an update published in 2016 and cited >1900 times). He is currently Co-Chair of the working group for the third guideline. MS conceived, developed and validated the seated saline suppression test which has since become the favoured method for definitively confirming the diagnosis of PA in most Australian and in a rapidly growing number of overseas institutions. He has also made major contributions to the understanding of how various physiological and pharmacological factors affect the aldosterone/renin ratio as a screening test for PA and in optimizing approaches to adrenal venous sampling, the most reliable method of differentiating unilateral (surgically curable) from bilateral varieties.

Publications: MS has published 1 book, 20 textbook chapters and >250 papers in peer-reviewed scientific journals. His journal publications have been cited >14,000 times ("h" index 59).

Grant Support: Since 2019, MS has received ~$16 million in research grant support. He is currently a CI on two MRFF grants and an NHMRC CCRE.

Invited Presentations and Collaboration: MS has been invited to speak at major meetings 137 times (99 international) and has collaborated with researchers in >20 international Units and all Australian states. In 2018, was one of six investigators awarded a highly prestigious Leducq Foundation Transatlantic Networks of Excellence Program grant ($USD 6 million) to study the role of potassium in hypertension.

Committee Highlights: MS is past President of the Asian-Pacific Society of Hypertension and of the High Blood Pressure Research Council of Australia. During his time as HBPRCA President, initiatives that were introduced under his presidency included launching of a successful bid for 24h ABPM to be assigned an item number to enable a Medicare rebate of ABPM services. He was a Member of the NHF BP & Vascular Disease Advisory Committee 1998-2013.

Community Engagement: As President since 1995 of the Queensland Hypertension Association, a non-profit organization dedicated to promoting self-care in the management of hypertension, MS has overseen all of its activities, including bimonthly educational sessions and preparation of educational material for the general community and health professionals. On numerous occasions, MS has provided information to the community on issues related to hypertension by media interview.

Peer Review: Previously serving on Editorial Boards for of J Clin Endocrinol Metab, J Hypertens, Clin Exper Pharmacol Physiol, and Nephology, MS is currently Editor-in-Chief of J Hum Hypertens and a member of the Editorial Board for Hypertension. He has assessed 100's of manuscripts for major international journals and served as grant application assessor on many occasions for major international and national funding bodies (including the NHMRC).
