Carsten Schmitz-Peiffer undertook his PhD with Professor Dick Denton at Bristol University (UK), where he investigated insulin signal transduction and the regulation of fat cell metabolism. He then joined the Garvan Institute to investigate mechanisms by which lipid oversupply could interfere with normal insulin action. His research showed an association between protein kinase C activation and lipid-induced insulin resistance in skeletal muscle. Subsequently he demonstrated a causative link between intracellular accumulation of the lipid intermediate ceramide and the inhibition of insulin action caused by the saturated fatty acid palmitate. It is thus clear that different fatty acids act through different mechanisms to reduce insulin sensitivity.

In addition, the study of mice deficient in specific protein kinase C isoforms has indicated that these enzymes play multiple and unexpected roles in the control of glucose and lipid metabolism, beyond the mere inhibition of proximal insulin signalling as currently widely assumed, and the understanding of the diverse mechanisms involved is a major focus of his work. His research group employs animal models of insulin resistance in combination with transgenic mice, as well as proteomic and lipidomic approaches at both the in vivo and in vitro level, to generate new insights into the molecular mechanisms involved in the defective insulin action seen in obesity and Type 2 diabetes.

Carsten Schmitz-Peiffer has been a member of the program organising committee for the Australian Diabetes Society annual scientific meeting (2009-2011), as well as a member of NHMRC Endocrinology and Biochemistry grant review panels (2006, 2011-2012). Within the Garvan, he has chaired the Faculty (2010), the Common Users of Building and Equipment (CUBE) Committee (1996-2010) and the Seminar Committee (2007-2012), and currently chairs the Facilities and Equipment Committee.
