Research interests

Dr Samantha Lavender has over 15 years research experience. Her research interests have focused primarily on the quantitative remote sensing of water bodies using their colour signature. Often called ocean colour, it’s used to quantify and concentrations and behaviour of what’s dissolved or suspended by modelling the optical properties. Research extends from the movement of sediments in the coastal zone to phytoplankton in the open ocean. Both topics link to wider issues, such as climate change, as remote sensing is an important monitoring tool. . She is also Chairman for the Remote Sensing and Photogrammetric Society and, at an international level, co-chair of the International Society for Photogrammetry and Remote Sensing Working Group VIII.7 (Oceans). Previously she was a committee member on the International Ocean Colour Coordinating Group (IOCCG).

Other research

The aims of Pixalytics Ltd are to:

  • Development of end user software solutions and educational material to promote the usage of spaceborne imagery and its underlying information by non experts.
  • Scientific research into environmental mapping and change detection including marine, fresh water and terrestrial applications.
  • Promote the commercialisation of academic and scientific research, including actively supporting the growth of the UK and international remote sensing communities.
