but of course you are not limited to these. Other research institutions such as universities or research insititutes elsewhere in Switzerland, Europe or the world can be an option too. Venturing further should be covered by the study regulations in most cases but might take a little more effort to get officially approved, so before applying for less traditional options make sure you have a reasonable plan for how to go about this and potentially check with the study administration or coordinator of the CBB degree before commiting to anything with an external company or research institute. The most critical part is to find someone at ETH (or an institution associated with the CBB degree) to grade your report. This cannot be done by an external person. A natural choice would be to ask your Mentor if she/he would accept this task.
How to apply?
How to go about applications is almost as varied as the places you can go to for your lab rotation. Some research groups advertise projects on their website or through one of the mailing lists at ETH. In many cases, however, a lab rotation happens because you, as a student, show some initiative. This could be by talking to a professor or postdoc after a lecture (... once these take place in person again) or by sending an email. If you choose this route, it is most likely advantageous if you know (roughly) what their group is currently working on and maybe have even read two or three of their (recent) publications to have a good idea of what they are spending a large part of their time on.
