Biography

I am a European Space Agency (ESA) Independent Research Fellow working in the Centre for Polar Observation and Modelling (CPOM) at the University of Leeds, a position which is co-funded by ESA, University of Leeds and British Antarctic Survey (BAS).

My primary field of expertise is Earth Observation (EO) of the Polar regions, where over the past >6 years I have gained a detailed technical understanding of how to process a range of EO data types (e.g. Synthetic Aperture Radar (SAR), and radar altimetry), from a large number of EO satellites (e.g. ERS-1/2, ENVISAT, TerraSAR-X, Sentinel-1, CryoSat-2), using multiple processing techniques (e.g. interferometry (InSAR), feature tracking, etc). I have used EO data to write journal papers on ice speed, grounding line location, ice elevation change, and calving front migration. I also have broader previous experience of working with multispectral optical and polarimetric SAR data for terrestrial applications, such as land surface type classification and vegetation health.

I have project managed or acted as project scientist on over 10 separately funded research projects, including the ESA Antarctic and Greenland Ice Sheet Climate Change Initiative (CCI), ESA Support to Science Element (STSE) CryoTop and GLITter projects, and the Natural Environement Research Council (NERC) iSTAR and ORCHESTRA projects. I am keen to explore non-commercial applications for exploiting EO datasets, such as developing the worlds first Near Real Time (NRT) ice velocity monitoring service, and supervising the development of a CPOM-ESA sea ice thickness mobile phone app (search ‘SeaIce’ on apple and android app stores).

Qualifications

  • PhD, Earth Observation of the Cryosphere, 'Locating Ice Sheet Grounding Lines Using Satellite Radar Interferometry and Altimetry', 2015, University of Leeds.
  • MSc, Space Studies, 2011, International Space University, Strasbourg.

Data Portal

I developed the worlds first Near Real Time (NRT) ice velocity monitoring service. Through this data portal, we distribute frequent maps of ice velocity for key outlet glaciers of the Antarctic and Greenland ice sheets in near real time. The velocity maps are produced by tracking moving features in synthetic aperture radar data acquired by the European Space Agency's Sentinel-1 satellite.

Teaching Interests

I deliver undergraduate, postgraduate and postdoctoral Earth Observation skills training through my teaching responsibility at the University of Leeds. I am a lecturer on the Ice and the Earth System (SOE3515) Year 3 undergraduate module, run jointly with the School of Earth and Environment and the School of Geography at the University of Leeds. In 2017 I was an invited lecturer on the University of Swansea final year Glaciology course.

In 2018 I look forward to lecturing on the Polar Prediction School on weather and climate in the polar regions, which will take place at the Abisko Scientific Research Station in Sweden, from 17 to 27 April 2018. https://www.apecs.is/events/upcoming-event-highlights/polar-prediction-school-2018.html

In 2016 I designed and ran the first ESA Earth Observation of the Cryosphere Advanced Training Course, hosted at the University of leeds, and co-sponsored by the UK Space Agency (UKSA) and the Satellite Applications Catapult. During the 5-day course, 60 post graduate, PhD students, and post–doctoral research scientists from around the world, learned advanced satellite data processing techniques from an expert team of international lecturers. http://seom.esa.int/cryotraining2016/

I am enthusiastic about communicating the benefits of satellite data through outreach, and more publically via news and media outlets. I have given outreach lectures to schools (Leeds Science Festival), delivered invited public lectures (Royal Meteorological Society); provided written comments for newspaper articles (Guardian, Independent, BBC News Online); given radio interviews (NPR, CBC, BBC Weekend Weather Show); and given live TV interviews (BBC World News).

Videos and Animations

I am really enthusiastic about making videos and animations to explain how satellite data can be used to better understand the Polar regions. A number of my animations are available to download at the links below, please feel free to make use of them!
