Ben is a molecular ecologist with diverse research interests, but currently all centred around the use of environmental DNA (eDNA) paired with next generation DNA sequencing to determine the biodiversity and function within environmental samples.

Ben joined ARU in October 2023. From 2019-2020 Ben held two Research Officer positions at the University of Essex. In the first position, he used DNA sequencing to look at the biological and agricultural quality of harvested rainwater collected in water harvesting ponds used by rural smallholder farmers in Kenya. During the second position he investigated the interaction of oil hydrocarbons with marine snow, the aggregation of organic and inorganic particles in the ocean, which sink through the water column and deposit on the seabed.
From 2020-2023 he held two Senior Research Officer positions, also at the University of Essex. In the first position, he used DNA sequencing to look at the biodiversity within urban soils compared to natural and agricultural soils. In the second position, he looked at the impact of offshore man-made structures, such as oil and gas platforms and wind turbines, on the surrounding benthic habitats.
