Dr Julia Goedecke


I supervise undergraduates in Cambridge, this year mainly students from Newnham, Emmanuel and Queens', but also from other colleges. Courses I teach include Linear Algebra (second year), Groups (first year), Vectors and Matrices (first year), Groups, Rings and Modules (second year) and Complex Analysis (second year). If you are a DoS and would like me to supervise for your college, you can contact me per email under jg352; however I tend to be quite full.

This Lent Term (2017) I am giving supervisions in IA Analysis I for Newnham, and IB Groups, Rings and Modules for Newnham, Queens' and St Catherine's. All students, please go to the Moodle site for supervision times (which will be advertised in an email to you all).

Groups Ia lecture course

In Michaelmas 2016 I lectured the Cambridge first year course on Groups (for the third time). All students should look on the course page on Moodle. Here is the lecture-accompanying blog Think for yourself, on which I particularly write about how to think about and learn maths at university.

Video Solutions

Video solutions to some example sheet questions.
You should only look at these once you've tried the question! Some data will be saved when you watch the videos, such as where you pause, what answer you clicked, etc. You can use the tick boxes on the list of videos to indicated if you have "completed" a question; I will also be able to see this information.
