Learning objectives
"On completion of the course, the student is expected to:
· Acquire the basic concepts of proteomics and metabolomics, and of the most relevant technologies, such as mass spectrometry of the different types of instruments and of the numerous quantitative proteomics and metabolomics techniques;
· Acquire the tools necessary to understand the advantages and disadvantages of the different approaches with regard to manual work load, costs, sensitivity and scalability
· Critically evaluate a proteomics workflow, from sample preparation, to the acquisition of spectra, to data analysis and interpretation
· Carry out raw data analysis on collected measurement raw data, such as conversion to standardized formats, quality control and identification of proteins through search engines
· Account for applications for proteomics and metabolomics in biomedicine and biology
"
Expected learning outcomes
"Student learning outcomes will be assessed by the faculty through a written test examining the student's learning of proteomic and metabolomic methodologies and in their use based on the syllabus carried out during the course.
The examination of the students by the lecturer will be mainly aimed at assessing the knowledge and understanding of proteomic and metabolomic techniques and data analysis and at evaluating the skills acquired by the student at the completion of the teaching itself. In particular, it will be evaluated the property of language used by the student, and the skills acquired to discriminate the choice of different methodologies and their possible integration to be applied to different scientific problems.

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
Lectures will be accompanied by hands-on laboratory work, during which the experiments carried out in the laboratory session will reinforce the concepts presented in the lectures. Practicals will also include computer work, through small computational tutorials carried out in small groups, with the following assignments: mass spectrum interpretation for peptide sequence reconstruction; launch of a protein ID search engine and discussion on data output; statistical and functional analysis of a quantitative proteomics experiment with MaxQuant/Perseus.
Class discussion will be also organized with presentation of real cases of proteomics and metabolomics studies, during which
students are required to actively interact.
Live discussions and questions during lecture and tutorials are encouraged
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.
Possible reference textbooks for proteomics and metabolomics are:
· Introducing Proteomics, from concepts to sample preparation, mass spectrometry and data analysis by J. Lovric (2011), Wiley-Blackwell Publishers
· Introduction to proteomics, Principles and Applications (2010) N. Mishra, John Wiley & Sons, Inc., Publication.
· Metabolomics: From Fundamentals to Clinical Applications (2017) A. Sussulini, Springer.
· Metabolomics in Practice: Successful Strategies to Generate and Analyze Metabolic Data (2013). M. Lämmerhofer and W. Weckwerth, Wiley‐VCH Verlag GmbH & Co. KGaA.
These textbooks will be then integrated with relevant recent reviews/articles on the topics covered during the lectures.
Video lectures and tutorials from past International Schools/Courses of proteomics and freely available online will also be indicated to the students
Assessment methods and Criteria
Given the highly interactive nature of the course, which includes practical and bioinformatics exercises, case studies 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 student will be based on their performance in the following aspects:

1) A compulsory written test, consisting of both open questions and multiple choice questions; the open questions will aim to verify the understanding of the principles of different approaches and strategies in proteomics and metabolomics, related to the simulation of real life scientific situations that embody what has been discussed in the course (40%)
2) An oral exam, based on the critical discussion of practical laboratory activities (assignments) and of a scientific article related to the topics addressed during the course (among a portfolio proposed by the teacher), which the students are expected to present and assess critically. During the oral exam the ability to use the specific disciplinary language appropriately and rigorously will be assessed (30%)
3) The class participation, creativity, ability to work in a team, during the practical assignments and activities (30%)
