Mary Clare Brown – Cardiff University
I obtained an MBiol in Biological Sciences in Cardiff University. I am now undertaking a PhD based in Cardiff University within the School of Biosciences. My project involves biomonitoring of anti-microbial resistance in UK freshwater environments using microbiological and genomic approaches. Antibiotic-resistant bacteria are one of the greatest emerging challenges to healthcare and agriculture settings worldwide, and this project will help to determine the impact of antimicrobial resistance spillover from agricultural settings so that we can limit its spread and maintain clean water.

Water is one of the most precious and important resources that humanity has to take care of. Yet, with new economies and nations falling into the trap of wild consumerism, the clean and available water becomes almost a luxurious commodity in many parts of the world. There are a number of strategies that can help to mitigate of even revers this negative trend, and certainly implementation of low-cost/affordable, environmentally sound technologies such as constructed wetlands is one of them. I am environmental engineer by training, specializing in sustainable water and wastewater management and with few years of engineering and research experience in constructed wetlands. For my PhD at University of Bath, I will be working on microbial ecology and fate of pathogens in constructed polishing wetlands, thus adding a new, exciting microbiological perspective to my research work.

The high mountains of central Asia (collectively known as the “Third Pole Region”) are home to more than 60,000 glaciers and around 9,500 km³ of ice. These frozen reservoirs contain more than 1000 times as much freshwater as Loch Ness and supply all ten of Asia’s great rivers – reaching more than a quarter of the world’s population. At certain times of year, glacial melt is known to be a dominant input into these rivers: it can account for as much as 70% of the summertime flow of the Ganga. However, very little is known about the chemistry of this meltwater input or how it influences downstream ecosystems. In my PhD project, I aim to quantify the glacially-derived nutrients (e.g. nitrate) and contaminants (e.g. mercury) within rivers in the Third Pole Region, and to assess their impacts on biological activity. I will be working with an interdisciplinary team headed by Jemma Wadham (Bristol Glaciology Centre), building upon my interdisciplinary background in Natural Sciences (B.A., University of Cambridge) and Physical Geography (M.Sc.R., University of Bristol).

Toby Champneys – University of Bristol
My name is Toby Champneys, and I study fish behaviour and ecology. I studied Zoology as an undergraduate at Swansea University, where I began to specialise increasingly in fish biology. I then undertook an MRes project in Swansea, looking at the effect of anthropogenic barriers on freshwater fish species. This inspired me to continue in the field of freshwater fish research, and I am especially passionate about topics relating to the conservation of freshwater ecosystems. For my PhD at Bristol University, I will be studying behavioural interactions between an invasive fish species called Nile Tilapia and native cichlids in Tanzania.

Elliot Druce – University of Bristol
After a BSc in Biochemistry and Genetics at the University of Nottingham and an MRes at Imperial College studying Molecular and Cellular Biosciences, I am now based at the University of Bristol studying for my PhD under the supervision of Prof. Patricia Sanchez-Baracaldo. My project uses genomic approaches to investigate how nitrogen from human pollution (fertilisers, waste water treatment) impacts phytoplankton populations in freshwater ecosystems, and to study how these phytoplankton species incorporate this excess nitrogen into their metabolic pathways.

Jack Greenhalgh – University of Bristol
I am based at the University of Bristol within the faculty of Life Sciences. After completing an MSc in Aquatic Science at UCL I was awarded a GW4 FRESH CDT. During my PhD I aim to clarify our understanding of the distribution of crayfish taxa and crayfish plague in the UK using environmental DNA. Environmental DNA is rapidly increasing the speed at which we can detect invasive species thanks to recent advances in molecular ecology. Furthermore, a water sample is all that is required from the field. The results of this project will allow policy makers and consultants to predict changes in crayfish distribution and aid white-clawed crayfish conservation.

Annalise Hooper – Cardiff University
My research at Cardiff University is focussed on identifying environmental triggers that induce Cyanobacterial production of Geosmin. Geosmin is a naturally occurring metabolite that imparts unpalatable earthy and musty flavours to drinking water, costing the UK water industry over £200 million per annum to treat. Current monitoring of Cyanobacterial Blooms only indicates a proxy for biomass, which doesn’t correlate with the Geosmin release. During my PhD I aim to establish a link between nutrient dynamics and Geosmin synthetase activity within drinking water reservoirs. Allowing a more pre-emptive model to be implemented to prevent future Geosmin problems.

Victoria Hussey – University of Bristol
I am a PhD student based at the University of Bristol, under the supervision of Professor Penny Johnes (Bristol), Professor Daren Gooddy (BGS), Professor Richard Evershed (Bristol) and Ruth Barden (Wessex Water). I completed my BSc (2014) and MScR (2018) in Geography at the University of Bristol, where I focused upon the impact of mycorrhizal fungi on phosphorus uptake by primary producers in the karst region of south west China. My PhD project is based within the hydrology research group at Bristol, where I will be researching how biogeochemical processes control the bioavailability and impact of carbon, nitrogen and phosphorus exported from constructed wetlands linked to small sewage treatment works (SSTWs), with a view to optimising wetland operational management to reduce the emerging risks for freshwater systems.

Fiona Joyce – Cardiff University
I obtained a BSc degree in Biology from the University of Leeds in 2011, and have since worked as an Aquatic Ecotoxicologist for an environmental consultancy in Cambridge. Having been awarded a GW4 Fresh CDT studentship, I am now based within the School of Biosciences at Cardiff University. As a PhD student, my research project will be to investigate the importance of riparian woodland for increasing the resilience of stream ecosystems to floods and droughts. This is a multidisciplinary project involving analysis of invertebrate food webs and interpretation of historical data to predict future outcomes of wooded and non-wooded streams in the context of climate change. This aims to inform policy makers and guide land management practices to help protect freshwater ecosystems.

Luke Lear – University of Exeter
I am based at the University of Exeter medical school, Cornwall campus, where I am embarking upon my PhD. This looks at antimicrobial resistance and virulence in freshwater microbial populations, using Galleria as a model immune system. The aim is to understand what can cause antimicrobial resistance to spread through communities and workout the source of the resistance. My background is in evolutionary ecology, with a strong emphasis on biological invasions.
Dominic Macias – University of Bath
I am a first-year PhD student working as part of the GW4 FRESH CDT. My research will focus on speciation of emerging contaminants in wetland systems. The aims of my research are to (i) understand the life-cycle of PPCPs in a full scale wetland system, (ii) verify key transformation pathways of PPCPs in lab-controlled wetland simulating microcosms and (iii) verify the effectiveness of the wetland system in PPCPs removal via biological activity assessment of selected chemicals using bioassays.

Josh Rainbow – University of Bath
I have completed an MSc in Biology and Biochemistry at the University of Bath, with a focus on biosensor development for disease diagnostics and monitoring. Before and during my studies at the University of Bath I have volunteered alongside PhD and postdoc students in the Department of Electrical and Electronic Engineering. During this time, I have helped develop a number of diagnostic devices for the purposes of DNA detection. My PhD project looks at the detection of DNA from several pathogens commonly found in fresh water sources. To do this I will be developing a multiplexed biosensing device to detect several associated DNA sequences within a single sample.
