Professor in the School of Chemistry, University of the Witwatersrand My research field is environmental analytical chemistry. My areas of interest include: analytical method development for water and soil analysis; the chemistry of acid mine/rock drainage; elemental speciation in polluted environments (water and soil systems); water quality assessment; remediation and mitigation aspects (development and modification of materials for the capture of pollutants in polluted water; constructed and natural wetland systems); value recovery (recovery of precious elements and rare earths from wastewaters; alternative uses of waste and wastewaters); geochemical modelling (predicting elemental speciation; forward and inverse modelling; 1-D, 2-D and 3-D reactive transport modelling; pit lake chemistry; evaporite and secondary mineral formation); and applications of artificial intelligence (optimisation and heuristic methods; classification; machine learning; deep learning; text minig; large language models; internet of things (IoT)). Computational competence: PHREEQC, PHAST, MODFLOW, FEFLOW, Geochemist’s Workbench, Visual Minteq, Statistica, Visual Gene Developer, Minitab, SIMCA, R, SQL, Python, C and Fortran.

Heidi McLeod

PhD Candidate in Human Geography, Lincoln University, New Zealand

PhD Candidate in Human Geography, Lincoln University, New Zealand I am a PhD candidate in Human Geography at Lincoln University, where I am researching Aotearoa New Zealand’s food system. I’ve channelled my personal foodie interests into understanding food regimes, commodity chains, systems and practices that bind up the way the world grows, exchanges, and consumes food. My study and current research focuses on food systems and practices in Aotearoa New Zealand, the potential of alternative practices, the extension of diverse community economy models, and the social benefits that accrue alongside environmental benefits. As a dominant player in the global agriculture market, we have substantial stakes in our own success.

Hugh Stanford

Researcher Associate, Centre for Urban Research, RMIT University

Researcher Associate, Centre for Urban Research, RMIT University Hugh is a Research Associate at RMIT University's Centre for Urban Research. His work centers on urban planning and urban greening, particularly the role of informal and neglected urban spaces in enhancing social and ecological outcomes. His recent research explores how urban greening can lead to improved biodiversity and human health outcomes in cities.

Harini P. Aiyer

Research Coordinator, College of Dentistry, University of Saskatchewan

Research Coordinator, College of Dentistry, University of Saskatchewan Harini P. Aiyer has a Ph.D. in Community and Population Health Sciences from the University of Saskatchewan, with a focus on socially accountable medical education. Harini also has a Master of Health Science in Reproductive and Cancer Biology from the Johns Hopkins School of Public Health, USA. Her research examines the areas of health equity, anti-oppressive methodologies, global health, and health professions education. She draws on her experiences as an immigrant in Canada while being mindful of the relative privileges and power dynamics in the spaces she navigates – both within and outside academia. In her current role as Research Coordinator with the College of Dentistry, University of Saskatchewan, she is examining how different dental schools in Canada use manual dexterity testing as a part of their admissions. Our team of researchers is also developing new manual dexterity tests for dental school admissions.
