Dr Lim is a Marine Geoscientist with interests in habitat mapping, sedimentary processes and geomatics/GIS. Dr Lim received his PhD in 2017 from University College Cork, where he utilised multiscale multibeam mapping coupled with ROV-video mosaics to understand the processes affecting a chain of cold-water coral reefs in the NE Atlantic. During his PhD, he was awarded several research grants, scholarships and awards which has now continued into his post-doctoral career. Dr Lim has participated in over 15 research cruises (chief scientist on five) and is a member of the EuroFleets + Scientific Advisory Committee. Dr Lim is a participant on the H2020 project “Integrated Assessment of Atlantic Marine Ecosystems in Space and Time” and is a researcher on the Science Foundation of Ireland-funded project MMMonkey_Pro.
