Alongside her work for the German Partnership Program for Excellence in Biological and Health Security, Jani is currently co-investigator for an Australian-Research-Council funded multi-site life course study on health and socio-economic vulnerabilities in Indonesia. Her postdoctoral research focuses on HIV risk behaviour by Indonesian female sex workers and she has been co-investigator for a Wellcome Trust funded study on determinants of malaria treatment-seeking behaviour and access to early detection and treatment in Indonesia. More generally, she is interested in mixed methods research to explore determinants and pathways of health-related behaviours.
