Dr Bert Van Loo

Dr. Bert van Loo’s main interests are within the wider theme of adaptive enzyme evolution. He studies both natural and artificial laboratory enzyme evolution, with particular interest in the adaptive evolutionary processes in relation to substrate specificity. He uses several model systems for these studies, most prominently the divergent evolution of phospho- and sulfohydrolases in the alkaline phosphatase and metallo-β-lactamase superfamilies. In addition to the latter, he is also looking into the evolution of enzymes that degrade xenobiotic compounds, in particular man-made environmental pollutants such as halogenated hydrocarbons and plastics. In addition to studying the evolution of these enzymes, both in nature and in the laboratory, he aims to harness the knowledge from in vivo adaptation to inform protein engineering strategies.
