About Our Team
Ass. Professor Heather Stewart
Director
Heather has more than 20 years of experience in multidisciplinary marine research and exploration with a focus on characterising the geology and physical character of the seabed and sub-seabed. She has participated in more than 35 marine expeditions globally and taken part on a number of remote land-based fieldwork expeditions.
Heather’s current research has two themes: the geomorphology and sediments of hadal and abyssal systems like subduction trenches and fracture zones; and assessing the dynamics, configuration, and sedimentary record of former ice-sheets. Working across disciplines Heather uses her expertise in shallow seismic, sidescan sonar, multibeam echosounder and sample data to work across a number of complementary fields.
Heather has published more than 100 peer-reviewed scientific papers and commercial reports, is an experienced scientific and public presenter having given more than 60 conference presentations and university guest lectures, in addition to over 20 invited public talks. She has completed a number of crewed submersible dives to abyssal and hadal depths, and recently, alongside expert submersible pilot and legend Kate Wawatai, became a member of the deepest diving all female submersible team.
Additionally, Heather is adjunct to the Minderoo-UWA Deep-Sea Research Centre where she is Deputy Director of Geoscience for the multidisciplinary team led by Prof. Alan Jamieson.

Dr Joana Gafeira
Senior Researcher
From her focus on ensuring that innovative digital processes are embedded into mapping activities, she co-developed the CoMMa Toolbox, that is an ArcGIS Pro toolbox created for semi-automated morphology mapping. Joana is an active member of the International Seabed Geomorphology Mapping (ISGM) Working Group, an ongoing collaboration that focused on developing multi-scale approaches for the creation of standardised geomorphology maps.

Dr Devin Harrison
Post-doctoral Research Fellow
Devin is a postdoctoral research fellow at Kelpie Geoscience. His research utilises high-resolution topographic models of the seafloor and complimentary geophysical and geospatial datasets to understand the geomorphic evolution and process landform relationship of the deep sea and the continental shelves. Furthermore, Devin has a wealth of expertise in geophysical soundings of terrestrial systems, including: glacial outwash systems and ice-marginal environments, peatland environments, and fluvial landscapes.
Devin earned his PhD at Newcastle University, United Kingdom. His PhD research focused on the utilization of geophysical techniques (e.g. ground-penetrating radar) to characterize the evolution of terrestrial glacial ice-margins and outwash plains in southeast Iceland. During his PhD Devin published a number of papers on glacial outburst floods and their geomorphic impact, and the long-term evolution of glacial forelands prone to repeat high-magnitude outburst floods.
Currently, Devin is working on the Inkfish open ocean project as a geoscientist with the aim to understand deep sea geomorphic processes, and characterise the spatial complexity and variability of the seafloor for habitat classification. Devin’s ongoing research interests include glacial geomorphology, the geomorphology of the deep sea, landform and landscape evolution, submarine landslides, peatland environments, and glaciofluvial sedimentology.

Dr Nemi Walding
Post-doctoral Research Fellow
Nemi is a postdoctoral research fellow at Kelpie Geoscience. Her research integrates high-resolution topographic models with photography and video analysis to investigate submarine volcano geomorphology and the characteristics of volcanic and volcaniclastic deposits to reconstruct the geological evolution of the seascape.
Nemi earned her PhD at the University of Hull, United Kingdom. Nemi’s research combined geotechnical experiments, analogue flume modelling, and fieldwork to investigate the geomechanical changes of pyroclastic material in response to moisture addition. Her findings underscored the significance of even minimal moisture variations in influencing pyroclastic density current behaviour and resulting volcanic stratigraphy. In addition to her academic expertise, Nemi has prior experience working in the geotechnical industry, with proficiency in soil and rock logging, as well as environmental and geotechnical sampling.

Dr Alex Petrovic
Senior Researcher
Alex is a marine geologist and sedimentologist with more than 10 years of experience in multidisciplinary marine research focusing on the characterisation of sedimentary depositional systems and the geomorphology of continental margins. He has participated in more than 10 marine expeditions in the NW Atlantic, Red Sea and Coral Sea, and led several land-based fieldwork expeditions focussing on limestone strata from the Triassic to the Holocene. Alex’s ongoing research spans all aspects of marine sedimentology and geomorphology with a special focus on carbonate depositional systems and their controlling factors, by analysing sediments, and utilizing oceanographic, hydroacoustic and seismic data. He has published more than 20 peer-reviewed scientific papers and book chapters and gave more than 40 conference presentations.
After Alex earned his PhD at Eberhard Karls University Tübingen (Germany) in the field of carbonate geology, he moved to Bremen University (Germany) for a post-doctoral research position where he investigated current-sediment interactions along the NW Iberian Margin and in Mid-Triassic carbonate successions. Due to his great interest in tropical marine sedimentology and carbonate-siliciclastic mixed systems he joined the CaResS research group at KAUST (Saudi Arabia). At KAUST, he oversaw a multidisciplinary and collaborative project that focussed on sediment dynamics along the modern NE Red Sea margin. In addition to his academic expertise, Alex has prior experience working in the limestone mining industry (Belgium).

Daniel Bates
Daniel is an undergraduate student at the University of Portsmouth studying their Earth Science course, specializing in a BEng in Engineering Geology and will be undertaking a placement year with Kelpie Geoscience. With an already established understanding in geotechnical analysis, geological mapping and sedimentology, Daniel is interested in applying his terrestrial geology techniques to a marine environment.
During his academic journey, Daniel has engaged in various fieldwork projects across the UK including geological mapping, fault mapping and coastal engineering profiling. This experience has granted him skills in data collection, analysis, and interpretation in understanding geological systems. At Kelpie Geoscience, Daniel contributes to research initiatives aimed at processing and analysing scientific data, as well as writing and publishing peer-reviewed reports and manuscripts under the mentorship of the Kelpie team of geoscientists.
His interests lie in implementing geotechnical studies, as well as to achieve a further understanding of the techniques used to record deep sea data to complete his dissertation during his final year.
