Associate Professor Melanie Rug
Melanie is a parasitologist with a research focus on molecular, biochemical and cell biological investigation of host-parasite interactions of the malaria parasite. She completed her studies in Biology with a Masters degree (Dipl. Biol.) on parasitic diseases in European crayfish and a PhD investigating the toxic activities of Jatropha curcas against intermediate snail hosts and larvae of schistosomes, the causative agent of Bilharziosis, both at Ruprecht-Karls-University of Heidelberg, Germany.
Melanie's interest in parasitology brought her to La Trobe University, Melbourne on a Postdoctoral Research fellowship from the DAAD. She later moved to The Walter and Eliza Hall Institute of Medical Research as a Senior Research Fellow where she studied different aspects of malaria parasite-induced trafficking pathways in the human red blood cell gaining extensive experience in the application of a wide range of light, atomic force and electron microscopy techniques.
In February 2012, Melanie joined the Centre for Advanced Microscopy (CAM) at the ANU and has been appointed as Director of the facility and the Microscopy Australia (link) Node in 2014. Melanie shares her passion for the “Inner Space” with researchers from various science disciplines across the Life and Material Sciences.
Melanie’s major research interest lies in understanding trafficking of exported proteins and (more recently) the lipid metabolism in Plasmodium sp.-infected erythrocytes, the causative agent of malaria. Her main research focus revolves around characterising functions of individual proteins by manipulating the parasite’s genome with molecular methods (reverse genetics). The generated mutants are then studied by biochemical analysis, immunofluorescence, Transmission and Scanning Electron microscopy (TEM and SEM) and often a combination of the beforementioned Microscopy techniques (CLEM), all of which can be performed on the high-end instrumentation at CAM

Teaching is one of the three pillars of the Centre for Advanced Microscopy together with research support and instrument and technique development. Imaging and analytical literacy are paramount for the next generation of researchers across the ANU and beyond.
CAM staff are involved in various teaching and outreach activities:
1) BIOL3203 Advanced Microscopy in Biosciences: convened and run by CAM staff together with faculty across various ANU schools and colleges (https://programsandcourses.anu.edu.au/course/biol3203)
2) 2-day module on ‘Correlative Light and Electron Microscopy in Parasitology’ in an international tertiary course “Concepts in Parasitology” run under the auspices of the Australian Society for Parasitology.
