What is the best and what the worst when doing a PhD?
A positive thing of doing a PhD is definitely that you constantly learn new things content-wise and methodically, not only in your field of research but also in more or less related research fields. That is something I really enjoy. Another point I like about doing a PhD or research in general is that you are involved in every process of a project, i.e. designing the experiment, collecting and analysing the data, and writing the paper. In the end, you really know what you did.
A downside of doing a PhD is that there are many ups and downs. Especially, during the downs, it is sometimes hard to stay motivated and not to question everything. Most of the time you manage to get through these moments by talking to friends and others PhD students and by having in mind that there are always better times following – even if you do not believe it.
Do you have any advice you would like to give to future PhD students?
Be careful about choosing the topic of your PhD! It helps a lot if you are really interested in the topic and, particularly, in the research question of your PhD. Especially, if you are experiencing a down, it is much easier to stay motivated if you really want to know the answers to your research question and not only because it is a part of your PhD.
Where do you see yourself in 10 years?
Hopefully, I will still do research but 10 years Is a long time to say.
