Official Title: Research Coordinator for the Institute of Science and Environment | Associate Research Professor
Shirley Weng In Siu received her PhD in Natural Sciences from Saarland University in Germany in 2010. Between 2012 and 2021, she was Assistant Professor in the Department of Computer and Information Sciences at the University of Macau and the principal investigator (PI) of Computational Biology and Bioinformatics Laboratory (CBBio). Since September 2021, she has been an Associate Research Professor at the University of Saint Joseph. Her research team focuses on computational drug design, biomolecular simulation, cheminformatics and machine learning. They are pioneering the application of swarm intelligence, machine learning, and deep learning to solve problems in protein ligand docking, drug target identification, and prediction of biological activity and toxicity. They are interested in finding new chemical and biological agents with medicinal potential. To date, their computational methods PSOVina, AmPEP, GWOVina, BESTox, LigTMap, etc. have been used and regularly cited (https://app.cbbio.online/). Shirley has great interest in the biophysics of proteins, membranes and polymers. Using molecular dynamics simulations, she has studied the conformational dynamics and mode of action of peptides from nature that are antimicrobial, anticancer, and neurotoxic. She has identified novel antimicrobial and anticancer peptides from the genomes of microbes. She has been involved in the development of membrane lipid force fields and more recently in the modelling of self-assembling monolayers on biochips.
Shirley is the author/co-author of more than 60 peer-reviewed journal and conference papers. According to the statistics of Google Scholar, her papers are cited more than 1,400 times and the author's H-index is 16. She is a member of the society Asian Association for Computer-Aided Drug Design (CADD-Asia) and Macau Computational Pharmacy Society. She has also been a member of the program committee of international bioinformatics and biomedical conferences.
