Support from the University
The university has some excellent resources to support postdoctoral research staff.
What is it with all these colleges?
Cambridge is a collegiate university – check Wikipedia to find out what that means (https://en.wikipedia.org/wiki/Collegiate_university) and check PdOC’s guide on how to get an affiliation with one of Cambridge’s 31 constituent colleges if you’re interested (http://www.pdoc.cam.ac.uk/guides/PdOC_College_Affiliation)
The Postdocs of Cambridge (PdOC) Society
The PdOC society is run by postdocs for postdocs and is a great resource for all things postdoc related: http://www.pdoc.cam.ac.uk/ . Sign up to their newsletter as well (https://lists.cam.ac.uk/mailman/listinfo/soc-pdoc-all-members)!
The Office of Postdoctoral Affairs (OPdA)
The Office of Postdoctoral Affairs is the University’s own support organisation for postdocs. They run many useful events and are a great provider of information and support regarding all aspects of postdoc life in Cambridge: http://www.opda.cam.ac.uk/
The Graduate School of Life Sciences
The GSLS organises a wide range of researcher and professional development training courses. http://www.rdp.cam.ac.uk is the place to learn more.
The University Careers Service
The University’s career service provides help for staff at all career stages. Their activities range from CV checks to workshops and mock interviews: http://www.careers.cam.ac.uk/ Don’t think Careers Service like you might have experienced at school. These guys really know what they are talking about and provide excellent guidance and advice.
Stay up-to-date with current seminars and talks
It would easily be possible to do nothing but attend seminars and talks every day while in Cambridge, so the trick is to make sure you find out about the ones that are most relevant to you. There are a great many email lists at the University you can subscribe to, and http://talks.cam.ac.uk/ is the place to find them. Make sure to hit up every single one that sounds interesting to you!
