|Autumn colours in Tromso|
In autumn the leaves of many trees changes from green to yellow or red. This is due to the fact that they stop making chlorophyll (the green pigment in leaves).
Chlorophyll is actually closely related to the macrocyclic compounds I have been working on in my Churchill Fellowship – hemes and corroles. These macrocycles don’t only give rise to lots of beautiful colours, but they carry out the chemistry essential for life.
Through learning more about the chemistry hemes and chlorophylls, hopefully I will be able to improve on the design of our nitric oxide breath sensor.

The reason I had come to Tromsø was Prof Abhik Ghosh, a chemist who has spent most of his academic career working on a unique family of compounds called “corroles.” Corroles are related haems from haemoglobin. While corroles and haem they have a similar structure, their chemistry is remarkable different. In particular corroles are able to stabilise highly reactive forms of metal ions.

I'm enjoying being back in a synthetic chemistry lab. Takes me back to my MSc in 2004 at Rhodes University. I was trying to make linear bi and tetrapyrroles and had quite a bit more hair then!
Now I work with cyclic tetrapyrroles. Thankfully there are other people to help with the synthesis because I'm pretty rusty

While in London I had the opportunity to visit the Churchill War Rooms http://www.iwm.org.uk/visits/churchill-war-rooms
I would strongly recommend visiting this museum, it is like going through a time machine back to the Second World War, it really helped open my mind to what live was like during this period and the incredible pressure that was on Churchill which revealed his amazing leadership skills and noble character.
