Ashraf Zarkan

Ashraf Zarkan is a Fellow at the University of Cambridge, affiliated with the School of Biological Sciences. His research focuses on bacterial infections, antibiotic resistance, urinary tract infections, biofilms, and persisters, with a particular emphasis on understanding and combating bacterial biofilms and antibiotic persisters using E. coli as a model organism. His work involves techniques such as bacterial genetic manipulation, antibiotic susceptibility testing, biofilm assays, and fluorescence-based detection of bacterial membrane potential.

Ashraf Zarkan is a Research Fellow in the Department of Genetics at the University of Cambridge, focusing on antibiotic resistance and bacterial signaling mechanisms. His research explores the role of bacterial biofilms, antibiotic persisters, and the human gut microbiome in antimicrobial resistance. Zarkan's work investigates how bacterial signaling molecules, such as indole, influence cellular responses to antibiotics and environmental stressors. He has published extensively on topics including the regulation of cytoplasmic pH in persisters, the impact of zinc homeostasis on antibiotic activity, and the potential of extracellular vesicles in combating biofilm formation. His studies contribute to understanding the complex interactions between bacteria and their hosts, with implications for developing novel therapeutic strategies.
