Dr Julia Horsfield

BSc (Hons), PhD, DipAppSci
Dr Julia Horsfield is a developmental geneticist based in the Department of Pathology at the University of Otago.
Julia leads a research group investigating the role of chromosome structure in animal development and cancer. Her specific research interest lies in cohesin proteins, which are present in all animals and important for cell division and DNA repair. As the name implies, cohesin proteins’ main function is to hold replicated chromosomes together until cells divide. However, they are also involved in gene expression and this is where Julia’s research focus lies, particularly in relation to Cornelia de Lange and Roberts syndromes.
Julia has worked with zebrafish as her model animal for the past 12 years. She moved from the University of Auckland to the University of Otago in 2007, introducing Otago researchers to zebrafish in the process. Her enthusiasm for the zebrafish animal model has attracted several senior researchers and their teams to zebrafish and this has ultimately led to the development of the new state-of-the-art facility.
