Professor Fan has been engaged in the research of prevention and control strategies and mechanisms of drug-resistant microorganisms. She has deeply explored the structure-function relationship of enzymes, revealed the molecular mechanism of enzyme property changes, and obtained mutant enzymes with excellent performance; she has also studied the inhibitory effect of enzymes on the formation of bacterial biofilms and virulence factors, and applied them to the adjuvant treatment of animal infections. Recent work has been published in International Journal of Biological Macromolecules (2024), Antimicrobial Agents and Chemotherapy (2023, 2 articles), Chemosphere (2023, 2 articles) and so on. She is currently presiding over National Natural Science Foundation of China, Anhui provincial funds, and university-enterprise cooperation funds.
