Dean’s commendation for PhD – Congratulations Dr Prabin Gyawali

We congratulate Dr Prabin Gyawali on being awarded his PhD and for receiving the Dean’s Commendation for Doctoral Thesis Excellence.

Dr Prabin Gyawali BSc, MSc, PhD
Thesis:  Sex Hormone Binding Globulin – Regulation and role as a marker of chronic disease risk
Supervisors: Professor Gary Wittert, Dr Sean Martin, Professor Leonie Hielbronn

Summary: Until now Sex Hormone Binding Globulin (SHBG) has only been considered as predominantly a liver derived carrier protein to deliver sex hormones to target tissues and prevent their degradation. Given that the production of SHBG in the liver is influenced by metabolic, hormonal and nutritional factors, for his PhD, Prabin, a Clinical Biochemist, used epidemiological methods to identify a new function of SHBG – as a marker of poor health and chronic disease risk, particularly cardiovascular disease, Type II Diabetes and prostate cancer in men.  For this he used biomedical and health data collected over time on men in the MAILES cohort study.

Impact:  SHBG may be an early and easily measured marker for screening of pre-symptomatic chronic disease and outcomes.  This epidemiological study now needs to be translated into an experimental clinical setting to examine the the usefulness of SHBG in screening for chronic disease. Given the strength of the results, however, Prabin advocates for routine measurement of SHBG when assessing men for cardiovascular disease.

We wish Prabin success in securing a post-doctoral position to allow him to continue his important work on SHBG, and wish him and his family all the best for the future.  Email:
