About Me

Research Scientist

I am an interdisciplinary remote senser and geographer with a keen interest in the interface where the physical world interacts with people. I am skilled in using remote sensing methods, and geospatial analysis, which I use to understand and monitor global environmental changes to facilitate sustainable adaptations and management. I also have a passion for stakeholder and public engagement.

Title: “A Spatial and Temporal Assessment of Sargassum Blooms in the Tropical Atlantic”

Supervisors: Prof Emma Tompkins & Prof Jadu Dash

- Interdisciplinary PhD (with elements of remote sensing, ecology, oceanography, biology, marine science, GIS, climate change adaptation, hazard management) with the aim of undertaking a cross-scale analysis of sargassum macroalgal blooms and beach landings to better define their spatial and temporal identity and improve management, forecasting and valorisation potential.

- Developed skills in communicating research i.e. completed a systematic review of floating and beach landings of sargassum (published 2020).

- Devised protocol and undertook fieldwork campaigns to Barbados and Ghana for coastal surveys to collect ground truth data of sargassum macroalgae including use of UASs and a field spectrometer.

- Designed GPS housing and deployed GPS trackers in the ocean to monitor movement of algal blooms in combination with Sentinel-1 and Sentinel-2 imagery.

- Long-term time-series analysis of algal blooms in the Gulf of Guinea using MODIS sensor imagery.

MSc Applied Geographic Information Systems & Remote Sensing

University of Southampton | 2018-2019

- Four-month placement at Snowflake Software (now Cirium).

- Developed competences in analysing spatial data in a variety of software packages including QGIS, ArcGIS, ENVI, CloudCompare, Cyclone, MS Excel, MS Access, Agisoft Metashape, and scripting in Python, R and IDL.

- Distinction award for dissertation “An Investigation into Flight Path Optimisation and their Interaction with Aviation Events".

BSc Geography

University of Southampton | 2015-2018

- Physical Geography focus and geospatial and remote sensing skills development including experimental geomorphology, advanced GIS, applied GIS, environmental monitoring.

- First class awarded for dissertation “Mt Merapi: A Volcanic Risk Assessment".
