The coupling of surface processes and tectonics is my field of study, and, as a third year graduate student pursuing a PhD, being actively involved in developing a community with similar interests is important to me. This discipline is still young and has room to grow in many directions - I want to part of the collective process directing this growth. I see this meeting as a great opportunity to meet and interact with peers as well as established figures in the discipline and spend time discussing the future and the past. I'm also interested in presenting and discussing some of my ideas related to the field areas I research. In all my field areas, large scale shifts in drainage network pattern, climate, and erosive regime have occurred in tandem with major tectonic events. Understanding how linked these shifts are is an enticing albeit difficult task. Input from other scientists will aid in my own research and could spark collaboration which would be helpful for me as an early career research scientist. There are not many meetings convened that so closely tie in with my own research interests which makes me very excited to participate in CTSP. Hopefully, there's space enough for another aspiring geomorphologist/tectonophysicist! +
The development of new fractures in exhuming bedrock is a pre-requisite for erosion in most alpine settings. Near surface fracturing is both driven by, and a driver of, bedrock erosion. While this process has largely been ignored in coupled tectonic-surface process models to date, it is important the next generation is developed with associated regulation and/or feedbacks in mind. +
The importance of interactions between tectonic and surface processes is becoming widely recognized. I have considered this type of interaction in numerical models that involved sedimentation in half grabens associated with large-offset normal faults. I also have experiences with coupling a three-dimensional long-term tectonic modeling code with a full-fledged surface process modeling code in varying degrees of generality. At this workshop, I would like to share my experiences with other participants as well as catch up with latest advances and accomplishments in this field of research. +

“Given that what is below our feet does not affect us, we essentially live in a 2D world”
When a middle school teacher proposed this to my class something about it seemed wrong, however I didn’t yet know enough to put my finger on exactly what it was. Now, almost ten years on, I know how misleading that statement is. Not only does the subsurface regulate a number of geological hazards, the rocks below our feet are intricately coupled to the surface we live on (and even the atmosphere). As such one of our most important roles as geologists in to study this ‘3rd dimension’, and in what ways it interacts with our ‘2D world’.
The curiosity to better understand this has driven me into a number of relevant research projects, in two main themes:
1) Ice sheet vulnerability and subglacial volcanoes. I have worked with a team in Edinburgh to identify nearly 100 new subglacial volcanoes in Antarctica. One of the major research questions we are currently working in is how isostatic rebound from thinning ice affects the rate and extent of volcanism (and thus the ice sheet basal conditions)
2) Volcanic hazard modelling and tectonics. Working with colleagues around the world, I have approached this topic from both the hazard prevention and global tectonics viewpoint. As part of a UNESCO world heritage bid we developed a global comparative framework for monogenetic volcanoes- one important result of this being the broad range of tectonic environments in which volcanoes occur. This work was recently condensed into a book chapter I co-wrote entitled ‘Volcanoes, plumbing systems and tectonics’.
I am starting a PhD in glacial mapping, crustal imaging and glacio-isostatic modelling in the US later this year. This workshop would be a great opportunity to meet some of the community in this field and develop potential future collaborations. It would also be a chance to present the relevant work we have carried out around the world and discuss our modelling strategies and algorithms.
