I completed a Bachelor of Arts/Bachelor of Science degree at the University of Melbourne (2000) studying topics as varied as Australian history, eukaryotic evolution, creative writing and cell biology. My passion for evolution and cell biology drew me to the intellectually vigorous environment of the McFadden Lab at the School of Botany, University of Melbourne, where I completed my PhD (2001-2005) examining the evolution, biogenesis and metabolism of the mitochondrion and apicoplast (plastid) organelles of the malaria-causing parasite Plasmodium falciparum. At the end of my PhD, I was awarded a CJ Martin overseas fellowship from the NHMRC. I decided to switch organisms and spent four stimulating years learning the ins and outs of the intracellular parasite Toxoplasma gondii in Boris Striepen’s lab at the University of Georgia in the USA. After a stint back in the McFadden lab, I was awarded an ARC QEII fellowship in 2011 and took up a lecturing position in the Research School of Biology at the Australian National University in 2012. At ANU, our lab focuses on how Toxoplasma gondii parasites acquire nutrients from the host cells in which they reside, then how they convert these nutrients into the building blocks the parasites need to proliferate.

I convene the 2nd year ANU Cell Biology course (BIOL2117). The course covers modern cellular biology, with a particular focus on eukaryotic cells. The course includes modules that reflect the research interests of lecturers who teach on the course, including evolutionary, plant and developmental cell biology. A particularly innovative aspect of the course is the six-week practical in which we use cutting edge genetic and cell biology approaches in attempting to localise previously unstudied proteins in Toxoplasma parasites. The prac culminates in contributing student data to the Toxoplasma research community. I also present lectures and practicals in the 3rd year ANU Parasitology course (BIOL3142), which will be revamped from 2020. I am the PhD convenor for the division of Biomedical Science and Biochemistry in the Research School of Biology, and the Biology discipline co-ordinator for the unique, research-intensive Bachelor of Philosophy (PhB) undergraduate degree.
