About Me

Understanding of enzyme-catalysed reactions, using a combination of the following techniques: synthesis of enzymatic substrates and inhibitors, isotope labeling experiments, enzyme purification, and enzyme kinetics. Major areas of interest are enzymes involved in the bacterial degradation of lignin and aromatic compounds, and enzymes involved in bacterial cell wall peptidoglycan biosynthesis, as targets for the development of novel antibacterial agents.

Current Projects

I am working on the following projects at the moment:

EU Horizon H2020 Project 鈥淶ero waste lignocellulosic biorefineries by integrated lignin valorization鈥� (ZELCOR) Co-ordinator S Baumberger (INRA Versailles). EU Horizon 2020 Bio-based Industries Consortium, grant agreement no. 720303.
BBSRC-FAPESP Project 鈥淟ignin valorization in lignocellulosic bioethanol plants: biocatalytic conversion via ferulic acid to high value chemicals鈥� led by Prof Tim Bugg, Dr. Fabio Squina (Univ Sorocaba), BBSRC reference BB/P01738X/1.

Research interests

My research group is currently studying bacterial enzymes for degradation of the lignin biopolymer found in plant cell walls, including DyP-type peroxidase enzymes, multi-copper oxidase enzymes, and Sphingobacterium sp manganese superoxide dismutase, for the conversion of lignin into renewable aromatic chemicals. We are also using metabolic engineering to convert lignin into high-value aromatic chemicals. My group also studies enzymes involved in bacterial cell wall peptidoglycan biosynthesis, as targets for the development of novel antibacterial agents.
