Course overview
This course will give an introduction of proteomics and mass spectrometry workflows, experimental design, and data analysis with a focus on algorithms for extracting information from experimental data. The following subjects will be covered in: (1) Protein identification (peptide sequencing, database searching, spectrum library searching, de novo sequencing, significance testing); (2) Protein characterization (protein grouping, top-down proteomics, post-translational modifications, protein processing and degradation, protein complexes); (3) Protein quantitation (metabolic labeling - SILAC, chemical labeling, label-free quantitation, spectrum counting, stoichiometry, biomarker discovery and verification). Examples will be provided throughout the course on how the different approaches can be applied to investigate biological systems. The class will be structured to include hands-on practical techniques for analyzing relevant proteomics datasets.

Learning objectives
At the conclusion of the course, the student will be able to:
Understand experimental design for mass spectrometry based proteomics;
Demonstrate detailed understanding of the possibilities and limitations of algorithms that are applied to proteomics data; and
Analyze a large proteomics data set using available algorithms.

Course Assessment
Readings and participation (30%): Students are required to attend class, to complete reading assignments and to participate in discussions and engage in healthy exchange of ideas. 
Project (70%): 

  • Choose a dataset from the Global Proteome Machine blog tagged as "Interesting Data"

  • Complete comprehensive peptide and protein identification and quantitation on this dataset (don't forget about quality control!)

  • Write up results as a paper including the methods used, analysis results, issues encountered and a comparison of your results with the associated publication.  Include all source code developed in the process. 

  • Deadlines: 

    • Tuesday March 7th 5-7PM: Project presentation part 1. Present the chosen data set and analysis plan (10 minutes)

    • Tuesday May 2nd 5-7PM: Project presentation part 2. Present final results (10 minutes)

    • Friday May 5th at 5PM: Final paper due (via email to kelly.ruggles@nyumc.org)


 General Policies
Late/missed work: You must adhere to the due dates for all required submissions. If you miss a deadline, then you will not get credit for that assignment/post.
Incompletes: No “Incompletes” will be assigned for this course unless we are at the very end of the course and you have an emergency.
Responding to Messages: We will check e-mails daily during the week, and respond to course related questions within 48 hours.
Announcements: We will make announcements throughout the semester by e-mail. 
Make sure that your email address is updated; otherwise you may miss important emails from me.
Safeguards: Always back up your work on a safe place (electronic file with a backup is recommended) and make a hard copy. Do not wait for the last minute to do your work. Allow time for deadlines.
Plagiarism: Plagiarism, the presentation of someone else's words or ideas as your own, is a serious offense and will not be tolerated in this class. The first time you plagiarize someone else's work, you will receive a zero for that assignment. The second time you plagiarize, you will fail the course with a notation of academic dishonesty on your official record.
