Dr Tan graduated with a BSc (Biotechnology) with Honours in 2008, and joined Monash as a lecturer in 2013 following completion of his PhD in phytochemistry. His research interests are in the area of biologically-active natural product discovery, particularly phenolic compounds. This includes identifying extracts and compounds that exhibit desirable properties such as antimicrobial, antidiabetic, anticancer, and antioxidant activity; as well as practical applications for natural products, such as anthocyanin-based food colorants and organic corrosion inhibitors.
