Expected learning outcomes
Student learning outcomes will be evaluated through an oral examination conducted by the course instructor. The assessment will focus on the student's understanding of the proteomic and metabolomic methodologies covered in the syllabus, as well as their ability to apply these approaches appropriately.
The oral exam is designed to assess not only the theoretical knowledge and comprehension of key analytical techniques and data interpretation strategies but also the practical skills acquired during the course. Particular attention will be given to the clarity and accuracy of the language used, as well as the student's ability to critically select, justify, and integrate different methodologies to address diverse scientific questions.

Prerequisites for admission
Basic knowledge of chemistry and biochemistry. Notions on the nature and structure of proteins. Basic knowledge of principle protein separation techniques (e.g. chromatography, electrophoresis, etc)
Teaching methods
The course combines traditional lectures with hands-on laboratory sessions designed to reinforce key concepts through practical experience. Laboratory activities include both bench experiments and computational tutorials, conducted in small groups. These tutorials will involve:
· interpretation of mass spectra for peptide sequence reconstruction;
· use of protein identification search engines and critical discussion of the output data;
· statistical and functional analysis of quantitative proteomics datasets using MaxQuant and Perseus.
In addition, students will engage in class discussions based on real-world case studies in proteomics and metabolomics, where active participation is expected. Selected lectures will be delivered by invited scientists currently leading proteomics research projects. These sessions will be moderated by the course instructor, who will facilitate discussion and provide synthesis.
Interactive participation, including questions and contributions during lectures and tutorials, is strongly encouraged throughout the course.

Teaching Resources
Students will be provided with the slides of the course, which must be suitably integrated with lecture notes. With regard to the proteomics and metabolomics parts, mainly due to the rapid evolution that characterizes these disciplines, there are few texts on the market that include all the topics covered, adequately up-to-date.

Assessment methods and Criteria
Given the highly interactive nature of the course, which includes practical and bioinformatics exercises and group work, it is essential to attend lessons regularly. Students who have followed at least 80% of the course are considered attending. The overall assessment of the students will be based on their performance in a compulsory oral test, consisting of questions aiming at verifying the overall understanding of the basic principles of the analytical methods ion applied in MS-based proteomics and metabolomics, the major challenges of these disciplines and the solutions developed to tackled them. Special attention will will be given to assess the understating of the different approaches and strategies in proteomics and metabolomics that are linked to the simulation of real-life scientific situations that embody what has been discussed in the course. The exam will also verify the students' understating of the most important data analysis approachess, including statistical analysis of large-scale, quantitative -omics data.
