|Meetingstatement_of_interest_submit=I am a PhD student under the supervision of Frédéric Herman at the Institute of Earth Surface Dynamics (University of Lausanne, Switzerland). In my project, I am studying the interactions between tectonics, climate, and erosion by using the Central Andes as a natural laboratory. I use inverse modelling of own low-T thermochronological data (thermoluminescence thermochronology, apatites/ zircons FT and He-dating) and a literature compilation to quantify the spatial and temporal exhumation history of the Chilean Andes. The constrained exhumation rates are compared to the structural and climatic evolution of the orogen. For this, I am re-implementing the code of Fox et al. ( 2014) and Herman and Brandon (2015). As a second project, I am investigating the influence of glacial erosion on exhumation at the latitude of Santiago, where the geology is well constrained and remained relatively stable since the last 23 Ma. To get insights into the amount of exhumation which cannot be explained by tectonically-driven rock uplift but is due to climatic variations, I model the expected thermochronological ages using geologically constrained fault kinematics and observed shortening rates and compare them to the observed ages. I use a modified version of the thermo-kinematic model of Riesner (2017, PhD thesis). I thus think that my project fits well into the scope of your workshop. Attending to it would allow me to get into contact with the community of earth surface process modelling, to learn about other modelling methods, and to contribute to the understanding of (inverse) numerical models using low-T thermochronological data.
|Meetingstatement_of_interest_submit=I am doing my PhD on the interactions between tectonics, climate, and erosion at the Institute of Earth Surface Dynamics (University of Lausanne, Switzerland) under the supervision of Frédéric Herman. In my project, I am developing an inverse model to quantify the spatial and temporal exhumation history of the Chilean Andes, using own and literature low-T thermochronological data as model inputs. The constrained exhumation rates are compared to the structural and climatic evolution of the orogen to get insights into the response of erosion to climatic variability and tectonic changes. As a second project, I am investigating the influence of glacial erosion on exhumation at the latitude of Santiago, where the geology is well constrained and remained relatively stable since the last 23 Ma. I use a thermo-kinematic model, modified from Riesner (2017, PhD thesis), to simulate thermochronological ages using geologically constrained fault kinematics and observed shortening rates.  
Modelling of thermochronometric data requires a good understanding of the surface evolution, since relief formation modifies the subsurface thermal field. Attending to your workshop would enable me to improve my competences in landscape evolution modelling. In turn, I could contribute to the understanding of (inverse) numerical models to constrain exhumation using low-T thermochronological data.
