The presentations will be given during the normal class time on March 28, April 2, 4 and 5.  Detailed schedule of talks is posted below. Each presentation will be 15 minutes in length plus 5 minutes for questions. You can use PowerPoint/Keynote or do a blackboard presentation. If you do a computer-based presentation please make sure you have all the necessary connectors and know how to operate the projection system. You are welcome to use the built-in PC which has PowerPoint installed but please make sure you know how to operate it and how to transfer your talk using  a USB memory stick.

March 28	Aswin Vishnu Radhan (2)	Philip Haupt (5)	Martin Cross (6)	Ryan Roemer (31)
April 2	Fan Yang (8)	Sydney Dufresne (12)	Max Werner (15)	Tarun Tummuru (17)
April 4	Vedangi Pathak (23)	Tim Child (24)	Mohammad Khalifa (25)	Eddie Ji (26)
April 5	Sebastian Gitt (7)	Rafael Haenel (33)	Oliver Yau Chuen Yam (18)	Brandon Stuart (27)
	Shadab Ahamed (30)	Stepan Fomichev (32)

The March 28, April 2, 4 presentations will be held during the regular class time. The April 5 session will be held between 12:30-14:30
in the same room as regular class.


Presentations will be evaluated by your peers based on the following criteria:

• Clarity of slides (blackboard presentation)
• Level of presentation: content should be suitable for the audience
• Pacing and selection of topics: the presentation should be reasonably paced with an interesting selection of topics
  
• Handling of questions: the speaker should be able to handle reasonable questions pertaining to the article and the background
  

Some general pointers how to give good presentations can be found here or here.

Presentations will be based on recent research articles. Some suggested articles are listed below. Please review the list and let me know by email before Feb. 15 which article you wish to present. You are welcome to use an article not on the list but please let me know well ahead of the Feb. 15 deadline so that I can approve and add it to the list.  Note: Articles marked with student names in [green angular brackets] have been taken and are thus no longer available.
