I get up, usually rudely woken by my little boy and battle the northern line to Birkbeck. When I am in the field I get up early, normally just before sunrise so we can be on the road as soon as it is light. There is always a lot of ground to cover, so maximising daylight hours is key.
My research…focuses on using energy released by earthquakes as a probe to image inside the Earth. Much like a doctor uses x-ray energy to image inside your body, we can do a similar thing using sound waves that are released by earthquakes to understand what the Earth is made of. I do this on a large scale, trying to image depths of hundreds of kilometres and understand what drives plate tectonics. I am particularly interested in volcanoes and how magma is generated, stored and transported before an eruption. Obviously volcanoes are not a big concern in the UK, so my research involves collaborating with people all over the world to understand what makes volcanoes work.
I teach… geophysics and scientific computing to geology and planetary science students in the Department of Earth and Planetary Sciences.
My typical day… involves heading in to work and a mixture of research, processing seismic data from beneath some of the areas I am working on (Ethiopia, Eritrea, North Korea, China, Chile), meeting with PhD students to discuss their research or with colleagues to discuss new proposals. If I am teaching I will spend time preparing for that. In the field, there is no such thing as a typical day. In Chile, we were accommodated by a cowboy in the mountains (including dinner at his house, with his horse joining us at the table), off-road driving for eight hours to deploy a station near an active volcano or white-water rafting to access a site for a seismometer deployment.
I became a scientist… mainly due to some inspirational teachers. At school my geography teacher, Ashley Hale instilled a fascination with the physical world. He was also an explorer, heading off to climb mountains in Africa, South America and Asia and updating us as he went. Some of that clearly rubbed off and I have been lucky enough to have a job where I can combine exploration of the world with an exploration of how it works. However, I have to admit that my PhD involved spending six weeks in the Seychelles. A life in science seemed a good idea after that.
My greatest professional achievement to date… has to be leading one of the first ever collaborations between the West and North Korea. This collaboration is focussed on a large volcano (Mt. Paektu) on the border of China and North Korea. We recently published papers showing the first images of the Earth beneath the Korean side of the volcano and also estimated the amount of gases that may have been released (a lot) when it erupted in 946AD. The work is ongoing despite all the recent political tension and shows that science has the ability to build collaborations during even the most strident political tensions.
My favourite part of the job… is the travel. As well as the Seychelles I have spent time in Mexico, Canada, Montserrat (a small island close to Antigua in the Caribbean), Japan, Ethiopia, Eritrea, China, North Korea and most recently Chile. The best bit is the chance to work with scientists from all these countries, learning about geology all over the world and learning their culture too. Also, volcanoes are in some of the most interesting and hard to get to parts of the world, so I get to satisfy the explorer part of me too.
After work… it is normally back to my family and a glass of wine or beer to relax.. .
