Research Overview

This newly formed team was officially set up from the Biomolecular Modeling and Design Division in Oct 2013 to be part of the new Translational Research division to work on three streams: therapeutic antibodies; drug design; and product development. Working closely with other groups in BII and both within and beyond A*STAR, the interdisciplinary nature of streams spans across molecular cell biology, computational science, complexity sciences, and biomolecular modeling.
