PhD Students

Faraaz Ahmad

Hi, I am from Manchester. Before my PhD I studied chemistry for four years at The University of Manchester and gained my MChem degree in Chemistry. I have always taken great interest in radiochemistry and petrochemistry hence after my undergraduate I decided to apply for a PhD in this area.

faraaz

I’ve now joined the Geomicro group to study my PhD entitled ‘Radionuclide fate in naturally occurring radioactive materials (NORM)’. The PhD will involve detailed characterisation of TE-NORM samples from the oil and gas industry including both non-active and active scales from selected sites, and other key materials such as sludges.

When I am not in the lab I like to hang out with friends, go to the gym, play & watch football and eat pizza.

If I had to choose a favourite mineral it would be diamond because it is the hardest naturally occurring mineral made from simple carbon atoms. Also, its name means unbreakable or invincible.

Adrian Cleary

I am originally from Stirling in central Scotland. I did a B.Sc in Environmental Geoscience at Edinburgh University and then stayed on another year to do an M.Sc in Environmental Protection and Management.

Blog photo AdrianMy PhD research is on the decontamination of radioactively contaminated land through bioreduction and the use of nanoparticles such as bio-magnetite and zero-valent iron

When I am not doing exciting geochemistry things I like hillwalking, baking and making things out of Lego.

My favourite microbe would have to be Lactobacillus casei as it is just super at helping me digest food.

Kat Dungan

I’m originally from Orpington, South East London but I’ve spent my last 4 years at Loughborough University doing an MChem. My Masters project was looking how  degraded PVC affected the solubility of nickel under geological repository conditions.

kathMy research will be looking at the key drivers of radioactive waste disposal, then relating these to the waste produced by a selection of potential future nuclear programmes for the UK.

Outside of research I love spending time outdoors (particularly camping and walking in the UK, scuba diving in warmer places) as well as getting involved in Girl Guiding. I also enjoy cooking and baking when I’m at home, although there’s room for improvement.

I can’t say I’ve thought about a favourite mineral – maybe uraninite (pitchblende) because of the role it had in the Curies’ work?

Lynn Foster

I am originally from Leicester and got my degree from the University of Leicester. I studied Biological Sciences, my modules focused on environmental microbiology, virology and genetics.

My PhD title is “Understanding microbial productivity in highly radioactive nuclear IMG_135836683967175-1facilities”. I will be looking at the genomes of microorganisms. Following this I will look at the RNA and proteins that they produce, with the aim of trying to understand some processes that allow them to survive in highly radioactive environments.

My hobbies when not working are going to festivals in the summer, horses and horsey activities like shows and demonstrations.

My favourite microbe – a bit difficult to say, I guess anything that falls into the category of extremophile. I was also really interested in the discovery of Pithovirus – which is the largest known virus that was revived from Stone Age permafrost. I like the stuff that challenges what we know about the limitations of life.

Edwin (Gnanaprakasam)

I am Edwin. Gnanaprakasam is my father’s name. For the international visa requirement, I took my father’s name as my surname as Tamils do not have the concept of surnames. Hailing from Kannyakumari, the southernmost tip of India, I received all my education in the Indian state of Tamil Nadu. After obtaining M.Sc and M.Phil in Biotechnology (Loyola College, Chennai), I migrated to Guyana as a missionary. As a Jesuit missionary I administered various parishes in Georgetown and taught part-time in the University of Guyana. Thereafter I spent more than a year in the US doing a spirituality course (Portland, Oregon) and working as a chaplain in St Peters University (Jersey City).

My work here in Mancedwinhester tries to understand the mechanism of arsenic speciation mediated by arsenic respiring bacteria in aquifer sediments. A meta-omic (genomics, transcriptomics and proteomics) approach will help establish the role of microorganisms in arsenic mobilisation in aquifers and help decipher the underpinning mechanisms. This deeper level of understanding will in turn help better target measures applied to arsenic mitigation.

As my hobby, I keep a constant vigil at cricket scores. Though I support Chennai Super Kings, my favourite cricketer is Chris Gayle. Besides cricket, I play badminton on Mondays, table-tennis on Thursdays and visit historical sites on Weekends (if possible). I read history from victim’s perspective. Watching historical documentaries is my big time hobby.

My favourite mineral from TODAY is amethyst because of its metaphysical properties and purple colour and of course it is my birthstone too.

Hollie-Louise Green

I am originally from Plymouth and grew up in Cornwall. Bored of the cows and lack of a night life, I ventured up to Manchester to undertake an undergraduate master’s degree in chemistry at The University of Manchester. Having not yet completed my mission of visiting every pub in Manchester I decided to stay and do a PhD as part of the NGN CDT.

I did my 3rd year project with Prof. Roy Goodacre, quantifying the limits of detection of certain food additives bound to gold and silver nanoparticles, using Surface Enhanced Raman Spectroscopy. My 4th year project was with Dr. Nicholas Lockyer in a comparative study of Secondary Ion Mass Spectrometry with Laser Post-Ionisation Sputtered Neutral Mass Spectrometry, for the quantitative analysis of metal alloys.hlg

Now I am a part of the schools of Earth, Atmospheric and Environmental Sciences and Chemistry with the project entitled “Radionuclide Biogeochemistry in Cementitious Wasteforms”. Where I will be focusing on the ability of microbial processes to mediate biogeochemical processes and radionuclide speciation in cementitious wasteforms, and how the heterogeneity of waste and cement grout affects this.

Outside of research I enjoy going to the gym, golf (pub golf that is) and I love cheesy chips with gravy but then again who doesn’t?!

And my favourite mineral is Labradorite, because it’s so pretty due to its iridescent properties. It also has the word Lab. and Rad. in there, and you’ll catch me in the Rad Lab, so win, win. I also like dogs.

Haydn Haynes

I am originally from Telford in the north of Shropshire. I studied for a Masters degree in Earth Science at the University of Manchester, and spent my final year researching the geochemical cycling of uranium in clays.haydn

My research studies the microbiology of bentonite, a buffer material intended for use in a geological disposal facility. The combination of high temperatures, radiation, and decreased water activity make for a hostile location. Understanding the microbial community is a crucial factor when considering the long-term stability of high-level wastes.

Outside of the office I enjoy watching a variety of sports including football (Shrewsbury Town FC), visiting new places, and walking. I also enjoy a wide variety of music, and play electric guitar.

My favourite mineral is the phyllosilicate montmorillonite, the main component of bentonite. It exhibits the unusual property of swelling in the presence of water.

Gina Kuippers

I was born in Aachen and graduated in Bremen as MSc Geosciences with the deep sea being my speciality, before I came to Manchester for my PhD.

ginaIn my current project I am working with isosaccharinic acid, a cellulolytic degradation product that is soluble and forms stable complexes with radionuclides. The focus of my studies is on the immobilisation of radionuclides through microbial break-down processes of the mentioned complexes.

Away from work I enjoy being active by hiking, long distance running, skiing and snowboarding… However, my biggest passion is Ultimate Frisbee, which is a combination of a great sport and seeing my friends. I am enrolled in several clubs and currently leading the Manchester Women’s team. Other than that I’m a passionate gardener and happy to try experiments in the kitchen.

I haven’t found my favourite microbe yet, but my favourite mineral would be a red silicate variety from the garnet group, known as Pyrope, as it is mined in Madagascar, South Africa or Sri Lanka, because of its incredibly deep red – my favourite colour too!

Rebeca Lopez

I’m from Tecate, a small city located in the northwest part of Mexico.  Before starting this PhD I studied a MSc in Biotechnology, at the Center of Research and Advanced Studies of the National Polytechnic Institute, in Mexico City.

waterfall resized!My PhD is titled “Exploring the metal-microbe interface using advanced mass spectroscopy techniques”.  I’m just starting, I’m new in this field and I find everything very interesting!  I think what makes this project particularly interesting is the exploitation of analytical methods that haven’t been widely used before to study metal-reducing bacteria, which will hopefully allow us to learn more about the mechanisms involved in these reactions.

I like to do a lot of things in my free time, sometimes I read, I do yoga, bake vegan desserts, go to concerts, take photos of anything that draws my attention…lately I’ve been taking online French classes.  But honestly, I frequently catch myself spending more time on the internet and social networks than I would like to admit.

If I had to choose a favourite microbe it would probably be Saccharomyces cerevisiae, basically because to it we owe the existence of two biotechnological products that I really love: bread and beer.  Regarding my favourite mineral, I like amethyst, I love its colour.

Babajide Milton Macaulay

I am from Obalende, a town that never sleeps, situated on Lagos Island in Nigeria, West Africa. I hold a Bachelor’s degree in Biology (focused on Plant Ecology) from the Federal University of Technology, Akure (FUTA) in Nigeria and an MSc degree in Sustainable Environmental Management (focused on Environmental Microbiology) from the University of Greenwich, UK. I was an Assistant Lecturer in the Department of Biology at FUTA before returning to the UK for my PhD studies.

miltonMy PhD research focuses on understanding the role of anaerobes and organic substances in the mobilisation of arsenic in groundwater. Hundreds of millions of people (not restricted to South and South East Asia as often reported) are at risk of arsenic poisoning. There is a lot of debate on the mechanisms that drive arsenic transport in aquifers, which inspired me to join the business of trying to resolve the unanswered questions, as well as the lack of data on arsenic in Nigeria aquifers, despite not knowing anything about rocks and minerals!  It’s been quite challenging so far, but the Geomicrobiology and Geochemistry research groups have got a rock-solid student support system which makes learning new skills/competences much easier.

When I’m not working, I love watching American movies, particularly action and horror. I also enjoy hanging out with friends and surfing the internet for hours. I must admit that I am an ardent fan of Manchester United, so the coincidence to study here in Manchester is more than fulfilling!

My favourite microbe will most definitely be Geobacter, mainly because I see it mentioned in almost every research article on arsenic that I have read. Sometimes I say to myself, ‘If Geobacter was a human, I would love to meet him.’

Shauna McLoughlin

I am originally from Widnes, a small industrial town in Cheshire. Before my PhD I gained a BSc in Environmental Science here at the University of Manchester.

The focus of my project is to understand selenium toxicity in the natural environment, in Photoparticular, an area of Limerick in Ireland where elevated concentrations of selenium are affecting agricultural land. Selenium is an important micronutrient to humans and animals with the narrowest range between deficiency and toxicity than any other element. Seleniferous areas often exist in very close proximity to selenium deficient areas making it an interesting element to study. My project will explore the entire selenium cycle from the source rock, regolith, soil, to the uptake in plants, examining the biotic vs abiotic processes involved.

Outside of research I have huge interest in human nutrition, so I spend a lot of time cooking healthy food! I also enjoy painting, drawing and photography and try to make time to visit art exhibitions. When I’m not in Manchester, I love spending time outdoors, whether it’s hiking or attending music festivals.

Even though it’s one of the most abundant minerals on earth I would have to say quartz is my favourite mineral, mainly because my birthstone Amethyst is a member of the quartz family!

Sul Mulroy

Originally I was from London a long time ago, but have lived all over the UK. Generally I pretend I’m from Manchester these days. Before starting my PhD I took the Geochemistry route through the MEarthSci course at Manchester and graduated in 2013. Then I worked in a hospital in London, went to Australia to find a job in mining (didn’t get one so did a bit of travelling and working across Western Australia), worked in Edinburgh for a year in a pub and was lucky enough to be saved from obscurity by getting this PhD.

DSC_0020My PhD project involves determining the structure of Co- and Ni- bearing Fe- and Mn-minerals from natural environments such as ocean-floor Mn-nodules and terrestrial laterite deposits. I will use Geobacter sulfurreducens to assess the influence of Fe-reducing bacteria on these minerals using both synthetic and natural samples, in order to study how the minerals evolve during bio-processing. What makes this project so exciting is that these organisms might potentially be used to mitigate the environmentally damaging and expensive processes currently used to turn raw materials into usable products. Also I get to do work at the Natural History Museum which, having gone through a prolonged and intense dinosaur infatuation as a child, means one of my life’s greatest dreams has come true.

Outside of the lab I like kickboxing (still rubbish at it), rock-climbing (not too bad at it), gold-panning (never found any gold), camping (total boss), drinking whisky (in moderation as per Government unit guidelines).  As for my favourite mineral, I’m in love with diamond but I’ll probably settle down with vernadite.

Tom Neill

I am from Loughborough, which is a town in the East Midlands, and my first degree was here at the University of Manchester in the School of Chemistry. I did MChem Chemistry with a research project in inorganic synthesis.

For my PhD I will be looking at radionuclide-containing colloids in the conditions relevant to effluent treatment processes at Sellafield. The aim of this is to understand the formation, stability, size and composition of these colloids and which factors are most relevant in stabilising and destabilising them.

Outside of work I like to stay active. I play sport quite regularly, in particular football. I also enjoy cooking (and eating) and reading.

My favourite mineral is not something I have previously given much thought! I would have to say malachite, just for the colour.

Sharon Ruiz Lopez

I am Sharon, and I am from Mexico. Born and raised in a small city called Atlacomulco, then moved to Mexico City where I studied in the Polytechnic National Institute. My BEng in Biochemistry was focused in Bioinformatics, although I liked it, I decided to look for something new, so I changed the topic and did my MSc in Biotechnology and Bioengineering working with groundwater remediation, molecular biology and aquatic toxicology where I learnt so much and I discovered the fantastic, sometimes stressful, research world.

sharonI also worked a few months in a pharmaceutical laboratory doing liquid chromatography and microbiological analysis.

My project is “Understanding the microbial productivity in highly radioactive storage facilities” and what I find interesting is the characterisation of microbial communities which are able to survive in extreme environments such as nuclear facilities, generating new information of the diversity of life in these environments. It is also interesting to consider the wide use of techniques like next generation sequencing in combination with metagenomic analysis and metatranscriptomic studies to determine the physiological adaptations of these microorganisms, making easier their future identification and improving our understanding of their interactions with radionuclides.

When I am not in lab I like hanging out with friends, watching sit-coms, listening to music, dancing, reading, chatting to my family and cooking (I’m not good at it, but I try).

About microbes, my favourite ones are protozoa, specifically Euglypha, a shelled amoeba which is common in soil, treatment plants, and stream bottoms where decaying organic matter is present. I like it because it is able to adapt to a wide range of conditions.

 

Adam Sims

I am from Burgess Hill, near Brighton, in West Sussex. I studied for four years at the University of Manchester on a MCHEM degree with a study in North America, in which I spent a year in Illinois at the University of Urbana-Champaign studying chemistry as well. I finished with a first class honours degree in chemistry from The University of Manchester.

AdamSims (1)My topic of research is development of an in depth study of the engineered clay barrier for deep geological disposal facilities for nuclear wastes. A number of clays are looked at in my project comparing high and low iron clays that are montmorillonites or nontronites. Challenges from heat, radiation, corrosion products, and groundwater impact clays differently and effects will be studied initially separately leading to coupled studies. The project is relevant now and within an expanding field keeping things interesting.

I am an active member of the University basketball and swimming teams which help de-stress from work and also take part in a number of runs throughout the year.

If I had to choose a favourite mineral it would be Cristobalite as you can always count on it to be there, in the right place, in highly heated clays giving some form of pattern to clay XRDs.

Agustín Solano Arguedas

Hi, proudly I am Tico, which it means that I am from Costa Rica. I have lived all my life in a town called Paraíso (Paradise in English), and yes, it lives up to its name!  Prior to coming to Manchester I obtained degrees in chemistry and biology from the Universidad de Costa Rica (UCR).  For my MSc thesis I looked at the synthesis and modification of a nano-biomaterial called hydroxyapatite. I studied its potential application in cancer therapies as a drug vector and as a fluorescent marker. After my studies, I spent time working as a researcher in the Forestry Resources Unit of the UCR (ReForesta). There, I was part of a team studying and restoring the Stone Spheres of Pre-Columbian Sites of Diquís Delta in Costa Rica (UNESCO World Heritage, 2014).

KODAK Camera

In my PhD I will be studying the geomicrobiology of cobalt in Costa Rican tropical ecosystems. I want to investigate cobalt levels in the soils and minerals before moving onto studying the interactions between fungi /bacteria and Co.  My idea is to work in Santa Elena (dry forest) and in Páramos (perhaps the most unexplored ecosystem in my country); both are beautiful complex and interesting sites.

In my free time I like to watch TV, chat with my family, read books, go to the movies and of course watch football (especially my team in CR: “La Liga” and my national team “La sele” as we called). I also like swimming, running, dance salsa and merengue and visit new places, especially archaeological sites or natural parks. I really enjoy hearing and feeling nature.

I would say that hydroxyapatite is my preferred mineral; it is very interesting as it is the main inorganic component in the bones of mammals, and it is super versatile and can be used in clinical/biological applications, as a catalyst, and in other chemical applications.

To finish, as we say in CR, Pura Vida!

Alex Tait

Hi, I grew up in a little town called Bromyard in Herefordshire, but I’ve lived in Manchester for over 10 years now. I moved here to study Biology and achieved a BSc from the Faculty of Life Sciences in 2008. Over the next few years, I developed a keen interest in environmental science, and returned to study in the School of Earth and Environmental Sciences, graduating with an MSc in Pollution and Environmental Control in 2012.at

After working in environmental consultancy for four years, I’ve decided to take on the challenge of a PhD. My research is looking at novel approaches for the remediation of Mercury from contaminated land and water. I hope to find solutions that can harness the ‘power’ of microbial communities to influence geochemical processes controlling the fate of Mercury in polluted environments.

Outside of university, I try to stay active through cycling, hillwalking and regular trips to the gym. I love the great outdoors and enjoy exploring new places. I’ve done a couple of trips to S.E. Asia – providing an opportunity to immerse myself in some exotic landscapes. I’ve also got a keen interest in music and film.

My favourite microbe has got to be the bioluminescent Photobacterium phosphoreum – lux genes enable it to emit a blue-green light, it forms symbiotic relationships that can light up the deep sea!

Luke Townsend

lukeHi, I’m Luke and I’m from Chorley in Lancashire. I did my undergraduate degree at the University of Manchester, studying Chemistry with Industrial Experience. My interest in radiochemistry came from my year in industry, in which I worked for Amec Foster Wheeler analysing nuclear decommissioning samples for radionuclides such as iodine-129 and nickel-63.

After taking a slight detour from radiochemistry for my master’s year (playing with upconverting nanophosphors), I’ve now joined the Geomicro group to study my PhD entitled ‘long-term fate of radionuclides during sulfidation’. The project is especially interesting to me as a chemist due to the interdisciplinary aspects of mineralogy and microbiology, which are somewhat foreign to me! My work will have implications towards broadening the understanding uranium and technetium mobility in geological disposal facilities and the environment.

In my free time, I enjoy playing and watching football, supporting the greatest team in the world; Blackburn Rovers. I’m also a keen runner and guitarist (not both at the same time) and love music in pretty much any shape or form.

My favourite mineral is schoepite, chosen for only two reasons; primarily, it’s really bright yellow, and it contains uranium (and so is at least a little relevant to my work).

Gianni Vettese

I’m from the wonderful (and definitely great) town of Great Yarmouth, but after 4 years of study in the fine city of Manchester (and at least another 3 to go) I feel I have truly made my home up North.

I did my chemistry undergrad in Manchester working in the Mills group, and for my masters project I studied the chemistry and reactivity of low coordinate samarium (II)gianni. My PhD research will involve studying enzymatic microbial metal reduction reactions. The work is great for me as it saddles more than one discipline but still revolves around chemistry. In short, I will happily spend the next three years of my life shaking soils.

Out of the office I am a family guy, mahoosive foody, watch obsessionist, terrible guitar player, and blindly believe the humble faith that ‘anything Italian is the best’. I love finding new and cool bars and restaurants about town.

My favourite mineral is apatite – I’ve always got one…

Josh Weatherill

I am from Norfolk and before coming to Manchester I did my BSc in Environmental Chemistry at the University of East Anglia in the fine city of Norwich. As part of my degree I also studied for a year at the University of British Columbia, Vancouver.

945043_10151565551067508_659985945_nIn Manchester I am studying iron oxyhydroxide (FeOx) formation in relation to radioactive effluent treatment. The high adsorptive capacity of FeOx, and their ability to co-precipitate aqueous ions makes them effective industrial decontaminants of radionuclides. Gaining a fundamental understanding of the FeOx formation process and how it is affected by solution composition is vital for achieving better control over such industrial processes. Specifically, my project is focused on understanding the fundamental process of FeOx formation in the Enhanced Actinide Removal Plant, an effluent treatment plant at Sellafield that decontaminates radioactive waste streams by co-precipitating dissolved radionuclides with FeOx phases.

Outside of academia I enjoy travelling, hiking, literature and art (looking at, not doing).

My favourite mineral would have to be ferrihydrite (specifically the 2-line variety) because it is the phase I encounter most commonly in my work and its properties are the subject of many exciting unanswered questions. However, a close second would be malachite because it is green, and green is my favourite colour.

Ellen Winstanley

I am from North Manchester. I did my MChem in Chemistry with Industrial Experience here at the University of Manchester. I spent my third year working as a chemist in an R&D department of Lubrizol Ltd, and then finished my Masters in fourth year by working on an organic chemistry project.

The title of my project is: Radionuclide uptake during iron floc formation: application toEllen Winstanley the Enhanced Actinide Removal Plant (EARP) Process.

I’m looking into the mechanism for how the precipitation of iron (oxyhydr)oxide flocs can remove various radionuclides from aqueous solution. Knowing how the radionuclides are sorbed to the iron is important because it allows you to see how different conditions could affect the sorption mechanism and hinder (or help) the uptake of radionuclides. This project is specifically aimed at the EARP procedure which processes some liquid waste streams at Sellafield.

Outside of research I love rock climbing (though I’m not very good) and eating cake.

Before I started this project I never imagined I would have a favourite mineral … ask me again in a year!

Kejing Zhang

Hi, I am from China. I completed a BSc in Environmental Engineering in Hubei University of Technology. Following this I spent a year at the University of Manchester and achieved an MSc in Pollution and Environmental Control.

My PhD research is on the Microbial Ecology and Biogeochemistry of Nuclear Facilities.

Outside of research I enjoy traveling and tasting local food from different countries. I also enjoy watching movies.

My favourite mineral? I do not know much about that. If I have to choose one, I would say silver because of its colour. My favourite microbes are algae.
