The role of the human spleen and platelets in the pathology of malaria infection in Timika, Southern Papua, Indonesia
Steven grew up in Indonesia and came to Australia in 2007 to complete his undergraduate degree at the University of Western Australia in Perth.
In 2012, Steven relocated to Darwin and joined Menzies as a research assistant in the Global and Tropical Health team, focusing on malaria research.
In 2019, Steven graduated with a PhD from Charles Darwin University and Menzies. His project explored the role of the human spleen and platelets in the pathology of malaria infection in Timika, Southern Papua, Indonesia.

Studi terbaru mengungkapkan, parasit malaria terbukti lebih banyak yang bersembunyi dan berkembang biak di dalam limpa manusia. Temuan tersebut mendefinisikan ulang siklus hidup malaria.

LEMBAGA Biologi Molekuler Eijkman mengatakan hasil penelitian yang dilakukan Eijkman dan rekannya menunjukkan sejumlah besar parasit malaria ternyata bersembunyi di organ limpa.
Study suggests immature red blood cells in spleen are targeted for invasion by P. vivax.
Groundbreaking new research has found large numbers of malaria parasites hiding in the spleen. Until now, it was thought that once malaria parasites reached the bloodstream, they circulated and multiplied only in the blood.
Ground-breaking studies published today in the New England Journal of Medicine and PLOS Medicine have found large numbers of malaria parasites hiding in the human spleen where they actively multiply in a previously unrecognised life cycle.

Blood platelets, neutrophils and the spleen have novel roles in people with malaria, according to new research from Charles Darwin University (CDU) and Menzies School of Health Research.
Could a new defence against malaria be found in human blood? Research suggests that human platelets — a component of the blood — form a first-line defence against the malaria parasite.
The study, which has just been published in the prestigious journal Blood, was led by Associate Professor Brendan McMorran at ANU and Professor Nick Anstey at Darwin's Menzies School of Health Research
The study, published by the Menzies School of Health Research (MSHR) in Australia's Northern Territory (NT), revealed that platelets attack and kill malaria parasites in the bloodstream.
The humble platelet is usually regarded as just a tiny cell that helps the blood clot. A study just published in the prestigious journal Blood has found that platelets attack and kill malaria parasites in infected humans to reduce the number of parasites circulating in their blood.
