My research interest lies in harnessing the power of bioinformatics tools to advance antiviral drug therapy. By employing molecular docking, predictive modelling, and structural bioinformatics, I aim to accelerate the discovery and development of effective interventions against viral infections. with the potential for repurposing existing drugs and identifying novel drug candidates to combat viral pathogens. By employing computational methods, I aim to expedite the discovery and development of effective interventions against viral infections.

Research Focus:

  1. Molecular Docking and Virtual Screening: I specialize in utilizing molecular docking techniques and virtual screening approaches to identify potential drug candidates that target key viral proteins. By computationally simulating the interactions between viral proteins and small molecules, I can expedite the identification of promising compounds for further experimental validation.
  2. Structural Bioinformatics: I utilize structural bioinformatics tools to gain insights into the three-dimensional structures of viral proteins and their interactions with host factors. By understanding the molecular basis of these interactions, I aim to design inhibitors that disrupt viral replication and pathogenesis.
  3. Repurposing Existing Drugs: I investigate the potential of repurposing drugs for antiviral purposes. By employing bioinformatics approaches, I analyze drug databases and identify compounds with the potential to inhibit viral replication or target essential viral proteins. This strategy accelerates the drug discovery process and offers cost-effective solutions.
