To continue my tradition of trying out all the Commonwealth countries, since my last post I have moved to the UK and begun a postdoc at the British Antarctic Survey in Cambridge. The UK is far nicer than Australians will lead you to believe – there are indeed sunny days, and gorgeous coastline, and great wildlife. None of these things are quite at Australian levels, but there are other things that at least partially make up for it. Like central heating, and the absence of huntsman spiders.

My PhD is now completely wrapped up, and I can officially use the title Dr., so I get very excited about filling in forms. For my postdoc I’m continuing to study interactions between Antarctic ice shelves and the ocean, but using a different ocean model (MITgcm), and focusing on a specific region (the Filchner-Ronne Ice Shelf in the Weddell Sea). This project includes some ice-sheet/ocean coupling, which I’m enormously, ridiculously excited about.

A postdoc is far more relaxing than a PhD, and far less existential. I know I’m only a few months in, but many of my colleagues hold a similar opinion. At last, there is no monolithic Thesis that everything is building up to, no pressure for all your research threads to converge into a coherent narrative before your scholarship runs out, no need to justify your continued existence (“how long have you been here, again?”) There is just a period of time for which your postdoc is funded, and you do as much science as you can during that time. You have more confidence in your own abilities, since you’ve done vaguely similar things before, and everyone else seems to take you more seriously too.

Much has been written on the mental health risks of doing a PhD, both in the scientific literature and in the media. I won’t pretend to be an alarming example of this, because many students have a much, much harder time than I did. But I did operate under elevated stress during the last year and a half of my PhD, and I noticed the effect this had on my life. Regular exercise was very effective in keeping my spirits up, but it didn’t really help the insomnia.

Here’s the pleasantly surprising bit: these effects appear to go away when you finish your PhD. I don’t know what else I expected – that I would be scarred for life? All I know is that I’ve slept well nearly every night since the day I submitted my thesis. And when I look at my giant list of things to do with my model, I don’t feel overwhelmed. I just feel excited.
