Anderson Shum's Biography

Anderson Shum, Professor, Department of Mechanical Engineering; Assistant Dean, Faculty of Engineering, University of Hong Kong

Dr. Anderson Ho Cheung Shum received his B.S.E. degree (summa cum laude) in chemical engineering from Princeton University, S.M. and Ph.D. in applied physics from Harvard University. He is currently a professor in the Department of Mechanical Engineering at HKU and Assistant Dean in the Faculty of Engineering. His research interests include microfluidics, microscaled fluid flows, emulsion-templated materials and soft matter. He was admitted to the Royal Society of Chemistry (RSC) as a Fellow (FRSC), nominated by HK for the 2017 APEC Science Prize for Innovation, Research and Education (ASPIRE Prize), and received the Early Career Award by the Research Grants Council of Hong Kong in 2012. He is current an editorial board member for Scientific Reports (Nature Publishing Group) and an editorial advisory board member for Biomicrofluidics (American Institute of Physics (AIP)) and Lab-on-a-Chip (RSC). He is also a reviewer for over 80 international journals including Nature Nanotechnology, Nature Communications and PNAS.

Biomedical applications, such as tissue engineering and drug delivery, require controlled assembly of biomolecules, cells and small molecules. These have been achieved either by a synthetic route, or using a directing substrate. Aqueous-aqueous Interfaces, which can be formed by inducing phase separation of aqueous solution containing two or more water-soluble additives, that can be salt, polymer and biomacromolecules, such as proteins and DNAs. Their bio- and cyto-compatibility can be ensured by choosing the appropriate additives, making these all-aqueous systems particularly appealing for applications that require precise and mild handling of delicate molecules and cells. In this work, we propose the use of the interface formed between two immiscible aqueous phases. These interfaces are selective to different molecules, as they are permeable to water-soluble additives yet exhibit preferential solubility through partitioning of the additive molecules based on this affinity to the aqueous phases. We show how these interfaces can be used to control the assembly of macromolecules, as well as cells into membranes and capsules that can be used for biomedical applications that require precise configuration of the constituent components.
