|Susanna Leong Su Jan obtained her B.Eng. (Chemical Engineering) Class I Hons and M.Phil. (Chemical Engineering) from the University of Manchester, UK, and her Ph.D. Chemical Engineering) from Cambridge University, UK in 2006. She joined the School of Chemical and Biomedical Engineering at NTU as an Assistant Professor in June 2006. Her research interests are in : (i) antimicrobial peptide engineering and development, (ii) synthetic biology, and (iii) streamlined bioprocessing for recovery of biomolecules.|
|My research interests are:|
- Bioprocess development studies for economical and simplified production of commercially relevant proteins and peptides.
Effective studies and widespread use of bio-inspired products such as recombinant proteins and peptides are often hindered by the lack of efficient manufacturing routes to produce them efficiently and cost-effectively, at large scale. My group has research interests in designing and developing efficient bioprocesses for the production of these recombinant products, which are often confounded by a vast range of combinatorial parameters available to study, understand and then optimize. New improved processes (both generic and molecule-specific for recombinant proteins/peptides) that can be readily validated and scaled-up are extremely desirable to underpin the fast-growing pharmaceutical and chemicals industries and to keep cost-of-goods low.
- Antimicrobial peptide engineering and development.
The importance of antimicrobial peptides as potential antibiotics is increasingly recognized as their use in diverse industrial applications continues to broaden. My group has research interests in the production and biomolecular engineering of new antimicrobial peptide variants, and structural studies for elucidation of their structure-function relationship for new applications. New knowledge in peptide production and processing technology generated from this work will also be invaluable to advance emerging peptide-based technologies which are sustainable.
- Synthetic biology.
Employing synthetic biology tools to address energy challenges.
