Ecroyd, Heath W.

Overview

Associate Professor Heath Ecroyd (PhD, Newcastle University, 2003) was an NHMRC Peter Doherty Fellow (2005-2009, University of Adelaide) and ARC Future Fellow (2012-2016; University of Wollongong). He heads a laboratory at the Illawarra Health and Medical Research Institute (IHMRI) researching the biochemistry and cellular biology of neurodegenerative disease. His main research focus is the role protein homeostasis (proteostasis) plays in preventing the aggregation of proteins associated with these diseases.

Research Overview

My research focus is in the field of protein homeostasis (proteostasis), an important area of research as disturbances in proteostasis can lead to protein aggregation (i.e. the clumping of proteins into large deposits), a pathological hallmark of many human diseases, including Alzheimer’s disease, Parkinson’s disease and Motor Neurone Disease (MND). My work focuses on the role of molecular chaperone proteins in proteostasis. This is because these are the body’s front-line defenders against protein aggregation. By identifying innovative approaches to activate molecular chaperones, my work aims to develop new drugs to treat, and ultimately prevent, neurodegenerative diseases such as MND.
