About me

I'm a researcher and data scientist working on projects in remote sensing, machine learning and ocean sciences. My PhD work used Google Earth Engine and satellite imagery to better understand coastal change over the last 30 years. I enjoy developing open-source remote sensing tools and creating web applications to visualise geospatial data and solving regression/classification machine learning problems (broad experience with PyTorch). I also have experience in solving decision-making tasks with reinforcement learning. Publicly available projects: CoastSat toolbox Web GIS project

The CoastSat shoreline mapping toolbox (recorded talk)

In this 20min Youtube video I present the open-source Coastsat toolbox which is capable of mapping satellite-derived shorelines from publicly available Landsat and Sentinel-2 imagery.

How to estimate beach slopes in the absence of field measurements? Here is a 12min Youtube video where I present a novel technique to estimate beach slopes from satellite-derived shorelines.
