About Program:
This 3-day workshop is designed to introduce participants to Protein-Protein Interaction (PPI) network analysis and its role in biomarker discovery. Participants will learn how biological interaction data can be collected, visualized, analyzed, and interpreted using bioinformatics and AI-supported approaches.
The workshop will focus on understanding how proteins interact within biological systems, how these interactions form meaningful networks, and how researchers can identify important genes or proteins that may serve as potential biomarkers for disease diagnosis, prognosis, or therapeutic research.
Participants will gain hands-on exposure to tools such as STRING database, Cytoscape, CytoHubba, NetworkAnalyzer, and AI-assisted interpretation workflows.
