Dr. Van der Ent studies the behaviour of trace elements (Ni, Co, Cr, Mn, Cd, Pb, Zn and REE) in soil and plant systems, and has a specific interest in the application of phytotechnologies that utilise hyperaccumulator plants (phytomining).

Dr. Van der Ent is an ecologist and biogeochemist whose research focuses largely on tropical systems. Since October 2014, Dr. Van der Ent has been leading a research initiative on phytomining at the Centre for Mined Land Rehabilitation (CMLR) at The University of Queensland (UQ). He has project managed a number of other programs, including an International Mining for Development Centre (IM4DC)-funded research project on copper-cobalt hyperaccumulator plants in Zambia, and industry-funded research projects on nickel hyperaccumulator plants in Indonesia (Weda Bay nickel on Halmahera Island), and in Australia on metallophytes in Queensland (Lucknow scandium deposit) and New South Wales (Broken Hill). 

He has had the opportunity to study metallophytes and hyperaccumulator plants on four continents including in the Chilean Andes, the Copperbelt of Northern Zambia, Broken Hill in Australia, Borneo, Sulawesi, Halmahera and New Guinea in the Asia-Pacific Region, South Africa, New Caledonia and various countries in Europe. 

Dr. Van der Ent is associate advisor of three PhD students, and principal supervisor for one PhD student, at The University of Queensland with projects in the field of nickel hyperaccumulation and phytomining. Previously he has also supervised an MSc student with a project on validating X-ray Fluorescence (XRF) for in situ measurement of trace elements in soil matrices.

The French-German film production company ARTE produced a full-length documentary about the research on phytomining undertaken by his team that was broadcast globally in January 2017.

Dr. Van der Ent obtained his PhD from The University of Queensland in 2014. Since then, he has been appointed to a joint postdoctoral position between The University of Queensland and the Université de Lorraine, France (UL), and since 2016 on a ARC Discovery Early Career Researcher Award (DECRA).
