Temmy graduated as a medical doctor from the University of Indonesia in 2003 and later awarded a Diploma in Tropical Medicine in International Health (2006) and a Master degree in Public Health- Disease Control (2010) by the Institute of Tropical Medicine (ITM), Antwerp. Her thesis on leishmaniasis project in Somalia has been honored with Prize of Development Cooperation of the Province of Antwerp in the same year.
She has worked extensively in developing countries with Médecins Sans Frontières (MSF) since 2004: as a technical officer in Indonesia, a clinician in South Sudan, India, Ethiopia and Somalia, medical referent in Darfur, Sudan and as a medical coordinator in Somaliland and in India. She served as Public Health Professional Fellow in WHO Regional Office for South East Asia in 2012-2013. With her various roles in these diverse contexts, including medical strategies and technical support in primary health care, hospital clinical care and management, HIV/TB vertical programmes, and response to emergencies, she has developed keen interest in the field of neglected diseases, especially Leishmaniasis.
In India, where she most recently served as Medical Coordinator since 2013, Temmy was involved in several collaborative projects, such as MSF-DNDi study of new treatment modalities for visceral leishmaniasis (VL) in Bihar, HIV/VL co-infection management, and participated actively in the efforts towards VL elimination in the sub-continent. She has also been a part of Cochrane review team for rapid diagnostic tests for VL and has several publications on the topic. With her skills in epidemiology and operational research she hopes to continue to contribute to the advance of leishmaniasis control and improve access to care for the disease for those who are in need.
