Rowena Martin carried out her PhD in ANU's School of Biochemistry and Molecular Biology, taking a multidisciplinary approach to understanding membrane transport in the malaria parasite. Her work spans the fields of cell physiology, biochemistry, bioinformatics, and molecular biology. In 2005 she took up a postdoc position at the ANU to pursue work she had initiated during her PhD on drug resistance in the malaria parasite and was awarded the 2007 Early Career Researcher Award of the ARC/NHMRC Research Network for Parasitology for this research. In 2010, Rowena was awarded the inaugural Australian Museum Eureka Prize for Early Career Research, a L’Oréal Australia For Women In Science Fellowship [YouTube], and an ACT Young Tall Poppy Science Award. She has also previously held a NHMRC Early Career Biomedical Fellowship (undertaken 2009-2012 at the University of Melbourne's School of Botany and ANU's Research School of Biology) and a NHMRC R.D. Wright Biomedical Fellowship (2013-16 at ANU's Research School of Biology). Rowena is currently an ARC Future Fellow (level 2; 2017-2020) in ANU's Research School of Biology.
The malaria parasite is a single-celled microorganism which invades the red blood cells of its host. Malaria remains a major infectious disease in many parts of the world, causing over 200 million cases and around 500,000 deaths per year. Moreover, malaria imposes horrendous economic burdens upon afflicted countries. An effective vaccine remains elusive and reliance on chemotherapy is under serious threat with the emergence of parasites that are resistant to most, if not all, of the antimalarial drugs available.
We use a range of biochemistry, cell physiology, molecular biology, chemistry, and bioinformatic techniques to study:
- Transporters of the malaria parasite and of other Apicomplexan parasites, with an emphasis on those involved in drug resistance
- Mechanisms of drug resistance and drug action in the malaria parasite
- Design of novel antimalarial drugs and antimalarial strategies
- Transporters involved in key processes in other organisms, including those encoded by plants, insects, and mammals.
- The functions and physiological roles of splice variants of transporters
