Susan is a young research assistant at the Eijkman Institute for Molecular Biology, Jakarta, Indonesia. Her research interests concern mainly the characterization of hepatitis B virus (HBV), which is prevalent in Indonesia. Since she joined the Institute in 2008, she has been involved in various laboratory activities as well as data analysis and preparation of published manuscripts.

Her current projects involved the analysis of HBV serological profile in Indonesian samples in association with the characterization of its molecular background, using a combination of bench work assays and proteomics/bioinformatics tools to achieve a thorough analysis of the data from both public health and basic research perspectives.
