Scienze omiche applicate (objectives)

TRAINING OBJECTIVES

1) Homics is a set of biomolecular disciplines that belongs to the life sciences and which is divided into different themes (genomics, transcriptomics, proteomics, metabolomics).
The main objective of the course is to enable the student to face the study of the main analytical techniques and instruments by deepening his knowledge of modern omic analyzes, essentially applied to a modern vision of early diagnosis. The student will be prepared to face the search for new diagnostic markers in clinical and non-clinical analyzes. At the end of the lectures, during the scheduled workshop (24h), students are given the opportunity to work individually on practical and practical topics. In this way, the student will acquire the ability to analyze the different protein expression starting from protein extracts and the possibility of applying modern analytical tools.

b) EXPECTED LEARNING RESULTS:

1) Knowledge and understanding:
Having acquired a good analytical ability in the field of omics and biotechnology

2) Knowledge and applied comprehension skills:
Knowing how to integrate the knowledge acquired in the individual disciplines into an interdisciplinary knowledge necessary to face any complex problem in the biotechnology sector, in particular being able to apply the knowledge of mass spectrometry to the various applications related to biotechnology.

3) Autonomy of judgment
Students will have to develop the ability to process complex and / or fragmentary information and to arrive at original and autonomous ideas and judgments capable of finding and critically selecting sources of bibliographic data, databases, and the
scientific literature. The autonomy of judgment is developed through the critical study of scientific articles.

4) Communication skills:
The student will be able to hold a critical public discussion on the topics covered in particular will be able to apply proteomics and metabolomics techniques for any scientific topic of interest .. Will be able to work in a team in the field of design and execution of experimental protocols as laboratory credits are foreseen.

5) Ability to learn:
The student will have the ability to identify, apply and develop innovative techniques in the relevant field of
work autonomously.
