    Research Fellow and Research Assistant

    To join our Ministry of Education Tier-3 project on “Saliva-assisted transmission of pathogenic viruses by blood-feeding arthropods in the Department of Biological Sciences/Duke-NUS.  This is an integrated, multi-disciplinary, comprehensive project to identify transmission enhancing proteins (TEPs) from vector saliva that play a critical role for Dengue (DENV) and Chikungunya (CHIKV) viruses. We aim to understand the biology of transmission, infection, and virulence of these viruses. This project will provide a strong foundation for developing novel strategies for combating other vector-borne diseases. The specific aims of this project are:

  • Identification of salivary proteins of Aedes aegypti mosquito that enhance transmission of dengue and chikungunya viruses
  • Understanding the roles of these salivary proteins and viruses with emphasis on transmission and vector competence and selectivity
  • Evaluation of vaccine candidate proteins in human cell lines and transgenic mouse models
  • Structure, function and mechanism of novel bioactive proteins from mosquito saliva

  • Candidates with an extreme interest in scientific research and a curious mind are invited to apply. Those with demonstration of strong experimental skills have advantages. Appointments will be made on 1 year contract basis in the first instance, with the possibility of extension up to 4 years.

    Purpose of the post

    Fast electron detectors are rapidly changing electron microscopy. These detectors allow probabilistic imaging of very many noisy, incomplete, chance observations that are then statistically classified and interpreted. This mode of imaging has enabled unprecedented high resolution imaging of dynamical and heterogeneous systems. 

    The Centre for Bio-imaging Sciences at the National University of Singapore is one of the few places in the world that develops new algorithmic approaches in such probabilistic electron microscopy. We are looking for motivated, aspiring scientists who would like to join us in developing this emerging field of statistical electron microscopy.
