Two tips that I found particularly useful from the video sessions with former PhD students were (1) to try and learn from others, to create opportunities to assist them when they run their own experiments and (2) talk to others as much as possible, and try to get feedback from someone knowledgeable when you're not an expert at the thing you're doing (e.g. using a new programming language).
1) One general question I have for the other PhD students/postdocs, is how do they organise their weekly schedule in the years that follow their first year, where the schedule is more flexible and unstructured?
2) What has other people experience with fellowships been like? How many have applied for one, and how are they using the fellowship to support them. I am definitely hoping to get more information on this topic.
