Research Interests and Projects: LacZymes (webpage)
As a researcher in the field of molecular biology, my primary interest lies in the intricate mechanisms of antimicrobial resistance (AMR), with a special focus on β-lactamases. My research journey, which began earnestly following the completion of my PhD, revolves around the evolution of these enzymes and their role in bacterial resistance.
Directed Evolution and Enzymology: One of my key interests is in directed evolution, a method that allows for the study of enzyme evolution in a controlled setting. This approach helps me understand how subtle genetic variations can lead to significant changes in enzyme activity and specificity, particularly in the context of antibiotic resistance. Additionally, my work in enzymology involves dissecting the kinetic and mechanistic aspects of β-lactamases, which is crucial for understanding how these enzymes confer resistance to β-lactam antibiotics.
Structural Investigations (X-ray Crystallography): Another significant aspect of my research is structural biology, specifically using X-ray crystallography. This technique provides a detailed view of the molecular structure of enzymes, allowing me to explore how structural changes in β-lactamases influence their function and interaction with antibiotics and inhibitors. These investigations are vital for designing effective inhibitors that can counteract antibiotic resistance.
Current and Future Projects: My current projects include exploring novel metallo-β-lactamase inhibitors, which are promising in the fight against carbapenem-resistant bacteria. In addition, by combining directed evolution, enzymology, and structural studies, I aim to develop a comprehensive understanding of these enzymes and design targeted strategies to mitigate their impact.
Current projects include:
a. Developing novel metallo-β-lactamase inhibitors.
b. Investigating β-lactamase-mediated resistance evolution.
c. Using directed evolution, enzymology, and structural analysis to explore enzyme adaptation in AMR.
d. Examining trade-offs in AMR evolution.
