Meet the Team

We are the Deep Earth Seismology research group, based in the Department of Earth Sciences at the University of Cambridge.

For anyone (interested in) joining the team, please check out our Code of Conduct and guide of expectations.

Profile: Dr Sanne Cottaar - Group Leader and University Lecturer Question: How did you become a deep Earth Explorer? Answer: As a child in the Netherlands I thought being a seismologist must be incredibly boring as I thought you would mostly sit around waiting for an earthquake to happen. I went to do a degree in geology as I liked sciences, but wanted to do something applied and observational, and the course required many weeks of camping each year! In my second year I got introduced to all the interesting things that could be observed with earthquake waves, and this inspired me to start doing research in seismology! Question: What are you working on right now? Answer: In my research I am looking at the source of the volcanism that created the Galapagos Islands 3000 km down inside the Earth! Besides this I supervise a number of research students, teach courses, communicate our science, and write new grant proposals to get funding to start new research projects. Question: What’s your favorite thing about what you do? Answer: The Earth only gives us limited clues as to what is happening inside it. Sometimes it feels like the Earth has set up a treasure hunt for us! My work feels like piecing together the different parts of the puzzle. Question: Best fact about our planet? Answer: The inner core is growing out of the outer core by millions of kilograms of iron a second, but this only adds about a millimetre of growth each year.

Dr Florian Millet Post-doctoral Researcher How did you become a Deep Earth Explorer? I love natural sciences, traveling and music. Seeing how varied Earth’s landscapes can be made me want to pick up geology when I had to chose a main subject in university. I find the fact that past and current deep processes affect the world we see today fascinating. And when you think about it, aren’t earthquakes the sound of the Earth? Florian’s text: What are you working on right now? With a particular focus on the region surrounding Greece and Turkey, I am trying to understand how subduction zones are linked to the deep mantle, around the transition zone (400 to 700km into the Earth) and even deeper! What’s the favourite thing about what you do? I was lucky enough to travel to three different continents to work on my research so far. I hope to be able to visit the remaining few and meet many more people and cultures in the future. Best fact about our planet? The Earth rotates at an almost constant rate, which makes the concept of “time zones” seem like the easiest thing to implement. How is it we seem to have made them so incredibly complicated then?

Profile: Stephen Pugh - PhD Student Question: How did you become a Deep Earth Explorer? I first became interested in Earth Sciences when learning about the amazing processes of plate tectonics, earthquakes and volcanoes in secondary school. After pursuing an undergraduate degree in Geophysics, I came to the University of Cambridge to discover more about the hidden world deep beneath our feet. Question: What are you working on right now? Answer: I am studying mantle plumes to understand what they can tell us about their origins, the upper mantle and mantle convection. Mantle convection is a remarkably important driving force in plate tectonics, and there are still many unanswered questions surrounding it. Question: How did you become a Deep Earth Explorer?

Answer: The Earth isn't quite a sphere, it actually bulges along the equator due to its rotation. This means that the furthest point from the centre of the Earth isn't the tallest mountain above sea level - Mt. Everest, it is actually Mt. Chiborazo in Ecuador which is over 6384 km from the centre of the Earth at its summit.

Profile: Stuart Russell - PhD Student Question: How did you become a Deep Earth Explorer? Answer: I studied geophysics at university and had so many questions left at the end of my degree that I wanted to carry on looking for answers! Question: What are you working on right now? Answer: I look at waves that interact with the core-mantle boundary, especially those that reflect from below, in order to try and understand the nature of the boundary. Question: What's the favourite thing about what you do? Answer: I enjoy that noone knows the answers to the questions we ask. We are working on cutting edge problems with unknown outcomes, and that is exciting! Question: Best fact about our planet? Answer: Most people know about tides that affect the Earth's oceans due to the gravity of the Moon and the Sun, however this doesn't only happen to the oceans at the Earth's surface - the liquid outer core also experiences tides which are believed to affect the Earth's magnetic field!

Profile: Jess Bartlet - Public Engagement Coordinator Question: How did you become a Deep Earth Explorer? Answer: As a Public Engagement Coordinator my role is to create dialogue about the mysteries of the Earth, thousands of kilometres beneath our feet with general public. I became a Deep Earth Explorer as the research group were keen to have someone lead on the public engagement programmes around their research. Question What are you working on right now? Answer: Right now I am working on the display boards for the Deep Earth Explorer research exhibition. I also help lead on the infrastructure and organisation for public events. Question: What’s your favourite thing about what you do? Answer: The creativity and innovation required to make ideas new and engaging in public engagement. A big part of enjoying public engagement with research is the chance to share research with public, which could affect their lives in future. Question: Best fact about our planet? Answer: The earth is adapting to change over time, somewhat like an organism. All of the Earth's large scale processes exist in such intricacy to support complex life. It is amazing when you think about. We have yet to find another planet that supports life as we know it!
