Advancing Proteomics: Techniques, Applications, and Future Directions

Proteomics is a rapidly advancing field that focuses on the large-scale study of proteins, their structure, function, and interactions within biological systems. This course provides an in-depth exploration of proteomics, covering its foundational concepts, cutting-edge technologies, applications in disease research, and its integration with other 'omics' fields. Students will gain knowledge of both experimental techniques and computational tools that drive the proteomics field forward.
