Research Students and Visitors


Grace-Lynn Chong


I love the great outdoors and I spend most of my time tramping or going for walks. It is therefore a privilege for me to study something that I find much joy, in being one with the environment. On a more serious note, I am investigating the seasonal cycling of fresh water lakes and different trophic status effects on the bioaccumulation of monomethylmercury in trout in the Rotorua lakes. Monomethylmercury is the more toxic component of mercury and poses as a health hazard thus, there is a need for such data. I am being supervised by Associate Professor Nicholas Ling, Dr. Adam Hartland and Professor Brendan Hicks (University of Waikato).

Since gaining a BSc Hon in Marine Biology at the University of Liverpool (UK), understanding the effects of human activities on the marine environment has fascinated me, and I am passionate about finding ways to protect it. My PhD research at the University of Waikato aims to establish the impact of two major stressors on estuarine ecological functioning: acidification from organic matter over-enrichment and elevated turbidity from increased sediment loading. I will investigate the potential for natural mechanisms to counteract or alleviate these pressures thereby maintaining ecosystem functioning. The buffering of sediment pH by calcium carbonate deposits will be studied with respect to acidification, and the functional role and importance of emerged estuarine sediments in buffering against turbidity through increased autotrophic production.

I am supported by a scholarship from the National Institute of Water and Atmospheric Research (NIWA) and supervised by Associate Professor Conrad Pilditch, Dr Adam Hartland, Dr Drew Lohrer (NIWA) and Dr Hazel Needham.

I am passionate about our natural environment and this drives both my professional and personal interests. I spend the majority of my spare time white-water kayaking, tramping and generally getting amongst it out there.  In my working hours, I pursue my interests in characterising, quantifying and tracking the behaviour of environmental pollutants.

I am now investigating the role of glacial sediments in the transport of environmental contaminants for my PhD research. I have been conducting this investigation in the glaciated catchments of Canterbury, New Zealand. These areas are subject to increasing levels of pollution, primarily from agricultural intensification. They are also fed by a number of the country’s most prominent glaciers, all of which are in rapid retreat.

The data I generate will assist in predicting how glacier-fed rivers and lakes respond to these pressures. I am supervised by Professor Jenny Webster-Brown (Waterways Centre for Freshwater Management, Lincoln and Canterbury Universities), Dr Sally Gaw (Chemistry Department, University of Canterbury) and Dr Adam Hartland (School of Science, University of Waikato). I am supported by the UC Doctoral and the Meadow Mushrooms environmental research scholarships.

Endocrine-disrupting compounds (EDCs) have the ability to be mitochondria stress-toxicants, and they are connected to human and non-human fauna reproductive illness and metabolic disorders. The aim of my PhD project is to investigate the presence of bisphenolic plastics and synthetic hormones, known to be some of the most persistent and potent EDCs in term of estrogenic activity, in fresh water systems in New Zealand and evaluate their effect, in term of stress, on native species. My studies are supported by the “Waikato University Doctoral Scholarship” and I am supervised by Associate Professor Nicholas Ling, Dr Adam Hartland and Dr Ryan Martinus.

I have an interest in environmental change, having previously gained an MSc in Environment & Climate Change from the University of Liverpool (UK). In my PhD research (commencing May, 2015) under the supervision of Dr Adam Hartland, Dr Beth Fox and Dr Shaun Barker (University of Waikato), and Marcus Vandergoes (GNS Science), I will be aiming to use geochemical proxies within speleothems and lake sediments to reconstruct changes in the terrestrial carbon cycle through time.

My PhD project focuses on the interaction between iron nanoparticles and phosphorus in lake systems with high internal loadings of iron. The objective is to understand how iron influences the bioavailability of P to autotrophs.  My studies are supported by a Waikato University Environmental Research Institute Scholarship.

My journey in Environmental Studies started in Iran, where I completed my MSc in Environmental Engineering at Iran University of Science and Technology. I have a strong interest in the fate and transport of contaminants in soils and aquifers. My PhD thesis is entitled “From soil to groundwater: assessing the leaching potential of cadmium across gradients of soil type and land-use”. In this study, I aim to deploy Diffusive gradients in thin films (DGT) solution probes in groundwater piezometers to monitor the concentration of Cd. This approach will be extended by measurement of the Cd isotope composition in order to characterise the Cd source(s) and biogeochemical processes affecting Cd mobilisation. I am supported by the Waikato University Doctoral Scholarship and supervised by Dr Adam Hartland and Prof. Louis Schipper. Aside from my academic interests, I enjoy exercising, camping, sport fishing and cooking!

My BSc (hons) dissertation will focus on the process of cave corrosion and how to measure this phenomenon in touristic caves. Cave corrosion rates are likely to be increased in touristic caves due to the higher atmospheric CO2 concentrations, but the importance of other aspects of cave microclimate (e.g. humidity) remains uncertain.  Understanding cave corrosion is important for the preservation and longevity of features in touristic caves, such as stalagmites, stalactites and flowstones.  My project is under the supervision of Dr Adam Hartland and in conjunction with Waitomo Group environmental officer, Carl Fisher.
