Professor Michael Horowitz

Professor of Medicine & Head Endocrine Unit

Adelaide Medical School

Faculty of Health and Medical Sciences

Eligible to supervise Masters and PhD - email supervisor to discuss availability.


Professor Michael Horowitz was appointed to a Personal Chair at the University of Adelaide in 1995 and has been the Director of the Endocrine and Metabolic Unit at the Royal Adelaide Hospital since 1997. His research activities are almost exclusively clinically based and relate primarily to gastrointestinal motor, sensory, and hormonal function, particularly in the context of diabetes mellitus, appetite regulation, critical illness and aging.

Professor Horowitz leads the National Health and Medical Research Council (NHMRC) Centre of Research Excellence (CRE) in Translating Nutritional Science to Good Health (2012-17). He is a co-author of 604 peer-reviewed papers and 40 book chapters.

He has been the recipient of a number of awards, including the Elder Prize for Scholarship at the University of Adelaide in 1995, the Distinguished Research Prize of the Gastroenterological Society of Australia (1999), the Eric Susman Prize of the Royal Australasian College of Physicians (2000), the Kellion Award of the Australian Diabetes Society (2009), a Masters Award for Sustained Achievement in Digestive Sciences from the American Gastroenterological Association (2010), An inaugural Fellow to the Australasian Academy of Health and Medical Sciences (2014), and the Royal Australasian College of Physicians 75th Anniversary Award (2014).

Research

My major research interests are in the two unrelated areas of gastrointestinal motor function and metabolic bone disease.  In both instances this research is being performed on a collaborative basis and has attracted international recognition.  The high level of scholarship and my pivotal role in both of these research programmes is evidenced by: (i) 212 papers in international, peer-reviewed journals and 22 book chapters.  – The majority of these papers have been published in high impact journals such as Gastroenterology, Gut, the American Journal of Physiology, Diabetologia, the American Journal of Clinical Nutrition and the British Medical Journal and they were cited in the scientific literature 311 times in 1993 and 380 times in 1994;  (ii) considerable success in attracting funding from competitive sources.  I have been the recipient of a total of approximately $1,978,000 from external peer-reviewed granting bodies since 1994 including 11 project grants, each of three years duration, provided by the National Health and Medical Research Council of Australia and grants from the Dutch government and the US Department of Health and Human Services;  (iii) the ongoing involvement of established overseas researchers of the highest calibre;  (iv) multiple invitations to participate in both national and international meetings, and;  (v) the ability to attract both Australian and overseas research fellows (the latter usually provide their own funding).

Teaching activities

During all stages of my postgraduate career I have made major contributions and enjoyed both undergraduate and postgraduate teaching.  My involvement in postgraduate teaching on both a national and international basis is increasingly sought and I have consistently received excellent ratings for my teaching from both medical students and physician trainees.  Major initiatives include:

  1. International training in gastrointestinal motility
  2. Establishment of research project in the medical curriculum
  3. Contributions to professional literature and editorial boards
  4. Royal Adelaide Hospital Research Forum

In addition to those stated my current activities in relation to teaching include:

(i)         Postgraduate

(a)  Tutorials in general medicine and endocrinology to trainees undertaking the Part I examination for the Fellowship of the Royal Australasian College of Physicians (about 2 hours/week);  (b) invited lectures at local, national and international meetings (including lectures to interns and regular presentations at medical grand rounds at the Royal Adelaide Hospital) (about 3 hours each week);  (c) supervision of higher degree students; and (d)  supervision of postdoctoral research fellows.

 

(ii)         Undergraduate

Tutorials (mainly bed-side teaching) and lectures in general medicine and endocrinology (metabolic bone disease, pituitary function, diabetes, gastrointestinal disorders) to 3rd, 4th, 5th and 6th year medical students (about 8 hours/week).  This includes weekly tutorials (about 3 hours) to 4th year medical students during their attachment to the Professorial Medical Unit.  The Departmental student assessments of these tutorials has been extremely favourable;  (b)  examination of 4th, 5th and 6th year medical students.   I have had a major involvement in the 4th and 6th year medicine examinations and organised the clinical component of the 4th year examination at the Royal Adelaide Hospital on a number of occasions.
