About me

I'm a data scientist/software developer/academic researcher working on projects in remote sensing, machine learning and ocean sciences. I develop open-source remote sensing tools, apply machine learning to solve to complex problems and create web applications to visualise spatio-temporal data (Django, Leaflet, PostgreSQL/PostGIS). I have developed the popular CoastSat toolkit, which uses Google Earth Engine to automatically track coastal changes over the last 40 years on satellite images. I also have broad experience with regression and classification machine learning problems (Neural Nets, LSTMs, SVMs on PyTorch) and have recently focused on solving decision-making problems with reinforcement learning (Q-learning and DQN). Publicly available projects: CoastSat , coastal webportal , RL optimisation

CoastSat

A global shoreline mapping toolbox with Google Earth Engine

CoastSat.slopes

Beach slope estimation from satellite-derived shorelines

WebGIS for coastal

A web dahsboard for satellite-derived coastal data

Data - coastal change Pacific

Dataset of time-series of shoreline change around the Pacific

Data - Slopes Australia

Dataset of beach-face slopes around Australia mapped from satellites

Outreach

Millions of satellite images reveal how beaches around the Pacific vanish or replenish in El Niño and La Niña years

This article in The Conversation explains in plain language our findings on the impact of ENSO on coastal change around the Pacific Basin.

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.

Beach slopes from satellite-derived shorelines (recorded talk)

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.

This work was presented at the Coast2Coast Webinar organised by Giovanni Coco, Kristen Splinter and Mitchell Harley.
