Arkasha Sadhewa is a Research Assistant at Menzies’ Global and Tropical Health Division, specialising in G6PD deficiency and its diagnostics to guide the treatment of P. vivax malaria. She also holds a position as a Public Health Tutor and Academic Support at Menzies’ Division of Education, supporting teaching activities in Biostatistics and Epidemiology Units.
She completed her undergraduate studies (2012) in microbiology at Institut Teknologi Bandung, Indonesia, studying the overexpression of M. tuberculosis’ PhoR sensor in E. coli. She started working with G6PD deficiency and its diagnostics in 2012 as a research assistant at the Eijkman Institute for Molecular Biology, Indonesia.
For her master’s studies (2018), she took part in the development of a novel quantitative G6PD test at the proof-of-concept level at the Burnet Institute and the University of Melbourne, Australia. She completed her PhD at Menzies School of Health Research, Australia, in 2025, with a thesis titled “Implementing Routine G6PD Testing at the Bedside in Indonesia: Collating Essential Information for an Informed Decision”.
