Research Interest
| Subject | Description | Research Interest (Goal, Target Indicator) |
|---|---|---|
| Salmonella enterica serovars Typhi | This project was designed to study the presence of linear plasmids in Bangladesh. A 27kb linear plasmid from this bacterium has been known to occur in Indonesian isolates. |
|
| Bacterial biofilms and antibiotic resistance | Molecular mechanisms of Bacterial biofilms and antibiotic resistance. Antibacterial resistance of bacteria: Phenotypic and Genotypic Characterization |
|
| Phylodynamics | My group also investigates phylodynamics of the indicator bacteria E. coli in order to assess its current status in the environment. | |
| Antibiotic resistance | My research interest also focuses on antibiotic resistance profile, resistance genes and mobile genetic elements. This interest flared from the fact that antibiotic resistance is a common phenomenon in Bangladesh. | |
| Cancer biology | I am interested to investigate microorganisms associated with different types of cancer with an intention to establish a link between a/more microbial agent and cancer. |
