I have always been fascinated by the way nature morphs simple building blocks to create more complex natural cures. This fascination shaped my career, which started by the isolation, structure elucidation and biological evaluation of various classes of phytochemicals, with the focus being iridoid glycosides (MSc studies). I then moved on to pursue my D.Phil. studies at University of Oxford, where I learned the modern aspects of (b-lactam antibiotics) biosynthesis, molecular biology and enzymology (structural and mechanistic). During my D.Phil. and postdoctoral studies time, I have developed myself into a rational-design protein engineer. Challenging chemical transformations and forcing enzymes, via engineering, to catalyse these reactions, with exquisite regio- and stereoselectivity, for biocatalytic purposes, is one of the main themes of my research. Extending my research from engineering enzymes to redesign of biosynthetic pathways to produce unnatural products of pharmaceutical interest is another objective for my research. As a teacher, I do strive to be well-informed, interactive and inspiring. One of my primary goals of teaching is to prepare both undergraduate and graduate students for a successful career.
