Sierin Lim is an Associate Professor of Bioengineering at the School of Chemistry, Chemical Engineering and Biotechnology at Nanyang Technological University, Singapore (NTU). Her research group focuses on the design and engineering of biological entities for applications in health and the environment. Specifically, her Bioengineered and Applied Nanomaterials Lab (BeANs Lab) uses protein cages and bacterial cellulose as the building blocks and a platform for formulation and delivery of active molecules to the skin. Her lab also explores the utility of protein cages to enhance contrast in imaging atherosclerotic plaques. In her Molecular & Cellular Bioengineering Lab (MCBe Lab), she leads a program in engineering plastic-degrading enzymes and microbes to up-cycle plastic waste to oil, cellulose, and cannabinoids using cyanobacteria, cellulose bacteria, and yeast. The innovations by students and researchers in her lab have resulted in numerous patent applications, four of which have been issued in the US and EU among other jurisdictions. She is currently serving as the Associate Dean of Global Partnerships at the NTU Graduate College. She earned her B.S. in Chemical Engineering and Ph.D. in Biomedical Engineering from University of California Los Angeles (UCLA) with a postdoc in the Department of Chemical Engineering and Materials Sciences at University of California, Irvine. In addition to her research work, Sierin is championing community developments at NTU and in Singapore, particularly women in STEM initiatives. She founded the Biomedical Engineering Society (Singapore) Student Chapter in 2009, Women@NTU in 2018, and Society of Women Engineers Singapore in 2021 of which she is the Vice President (Academic). She is the chair of Promotion of Women in Engineering, Research, and Science (POWERS) program which she co-founded in 2020. In 2013 she received the L'Oréal-UNESCO Singapore for Women in Science National Fellowship and in 2020 the Inaugural Singapore 100 Women in Tech List. She’s a STEM Ambassador for Girls2Pioneers section of the United Women Singapore.
