The Journal Club meets most Tuesdays. Talks are currently held virtually.
Date: Please see dates below
Time: Usually 2pm. See below for exceptions to this starting time.
Venue: Online. Links to join will be sent out via email.
Contact for queries: Daniel Nickelsen
The "Journal Club" seminar provides a forum for us, and our visitors, to discuss current work, perhaps to benefit from feedback before it is submitted to a journal. Presenters are encouraged to focus on the context of a problem or result and the reasoning it involves, instead of presenting a management-level summary of polished results. Insights into the work, progress, pitfalls of methods, critical assumptions, and similar discussion points will be appreciated. For a fruitful discussion presentations should be accessible, carefully choosing the abstraction level and the technical details shown. Usually a taste of the methods involved will be more beneficial to the audience than a complete proof. It is hoped that both the audience and the speaker will benefit from an example of how to engage in research.
