Dr Yi-Yeoun Kim - Postdoctoral Research Assistant

Yiyeoun

I am a materials scientist with expertise in the fields of biomineralisation, controls of crystal nucleation and growth and functional organic/inorganic hybrid materials. The focus of my research is understanding and adopting the structure/property relationships and the process inspired by biominerals, which reveal fascinating complex and hierarchical structures and superior mechanical properties, in order to design novel hybrid organic-inorganic materials on a various length scales.

Prior to joining the Meldrum Group, I was a visiting scientist (industrial postdoctoral program) working for the strategic research and discovery group at Specialty Minerals Inc. PA, USA. I initiated to explore the industrial applicability of a biomimetic synthesis to develop new functional hybrid materials. Prior to this, I have worked on templated Ca-based mineral thin films and hard tissue implants with Prof. Laurie Gower, and received my PhD degree from the department of Materials Science and Engineering at the University of Florida, USA. I received M.S. and B.S from the department of Polymer Science and Engineering from the Pusan National University, South Korea.

Dr Alex Kulak - Materials Characterisation Specialist

Alex

I’m a chemist. During my scientific career – which has lasted over 25 years – I have worked in many different fields of chemistry: organic, organometallic, analytical, inorganic and nanochemistry (to name but a few). During the last 10 years I have worked in material science – biomineralization, the synthesis of hybrid materials and nanoparticles, crystallization in the presence of soft and hard templates and the 2D and 3D aggregation of nanoparticles. I like this kind of “chemistry” a lot because you can see the results of your reactions directly with your eyes (through TEM, SEM or optical microscopes).

In my time out of the laboratory, I like to cook and drink, walking in the forest and collecting edible mushrooms (when they're in season). I've also been known to have a few glasses of Laphroaigh (...comment added by FCM).

Dr Shunbo Li - Postdoctoral Research Assistant

Shunbo

Hi, this is Shunbo. I received my BS degree in Physics from Chongqing University, in 2009. Then I went to the Hong Kong University of Science and Technology, where I obtained my PhD degree in 2014. After that I joined Prof. Fiona Meldrum’s group in School of Chemistry at University of Leeds. My research interest is mainly focused on Micro/Nanofluidics, Micro/Nano-fabrication for Microdevices and functional electromagnetic materials, and Biomineralization. My project here is “study biomineralization in micro/nano-fluidics”.

Dr David Green - Postdoctoral Research Assistant

David

My research in Leeds is towards achieving a greater understanding of small molecule occlusion in inorganic single crystals. By developing new strategies for sample preparation and characterisation; and expanding on current datasets, we aspire to develop a more thorough theory as to which materials, how and why they occlude. Along the way, new developments in morphological, structural, kinetic and perhaps even functional control can be assessed with the screening of large numbers of small molecule additives and inorganic crystalline materials. This work is in conjunction with modelling and computational chemistry groups in Sheffield, York, Imperial and Copenhagen.

In my spare time, I enjoy football (Up the Town!), playing and recording music, writing and a good pint of beer.

Dr Shuheng Zhang - Postdoctoral Research Assistant

David

My research interest lies in the field of crystallisation of various materials, biominerals, pharmaceuticals, opticals, etc. My postdoctoral project in the Meldrum Group towards the fundamental studies of crystallisation, using microfluidics as a tool. Screening and optimisation of crystal habit, crystalline phase and crystal size distribution can be achieved with high throughput microfluidic techniques and the effect of confinement.

Prior to this project, I received my Ph.D. degree in the Veesler group at CINaM, Aix-Marseille University. My Ph.D. is focused on the design and validation of a versatile microfluidic platform for screening and optimisation of protein crystallisation conditions.

Outside the lab, I like hiking, jogging and yoga. My cat, who kindly came with me to Leeds, likes eating, sleeping, biting and scratching me.

Dr Thembaninkosi Gaule - Postdoctoral Research Assistant

Thembi

Biological organisms, such as diatoms, have the amazing ability to fabricate a wide variety of inorganic materials into complex structures. These genetically encoded structures are made with great precision and detail far exceeding our human capabilities. The ability of biological systems to synthesise inorganic materials under physiological conditions has inspired the development of new approaches to inorganic material synthesis. Prof. Fiona Meldrum, Prof. Michael McPherson and I aim to use biomolecules to direct the in vitro synthesis of inorganic materials. We will use directed evolution techniques coupled with droplet based microfluidics to synthesise genetically encoded inorganic materials. As my research progresses, structural studies will be carried out in order to relate the structure of the active biomolecules to their function.

I received my PhD degree from the School of molecular and cellular biology at the University of Leeds. My research focused on the biophysical and mechanistic properties of copper amine oxidases.

Dr Angela Bejarano-Villafuerte - Postdoctoral Research Assistant

Angela

My name is Angela Bejarano-Villafuerte. I am Chemist from the University of Seville (Spain). I did my MSc in Nanoscience and Nanotechnology and MSc in Fundaments and Applications of Synchrotron Radiation at the Autonomous University of Barcelona (2010 and 2013). My PhD in Nanoscience was conducted in the Material Science of Barcelona Institute (ICMAB-CSIC) and done at the University of Barcelona (Spain). In 2014, I worked as a Postdoctoral researcher in the University of Limerick (Ireland) in the SSPC (Synthesis and Solid State Pharmaceutical Centre) framework, involved Nanoparticle–Stabiliser Interactions.

Currently, I am a Postdoctoral Researcher Associate to the project "Control of Crystal Nucleation on Surfaces" to study crystal nucleation from vapour, from liquid and from solution on surfaces. My research has been focused on the heterogeneous nucleation control for several approaches as chiral compounds on micropatterned surfaces crystallisation study in order to determine the chiral recognition at the interface.

Outside the lab, I like swimming and dancing. I love travelling, photography, cinema and series. I enjoy meeting new people and a nice dinner in a good company trying to fix the world.

Joe Marchant - PhD Student

Joe

Hi, I’m Joe. I am from Castleford, West Yorkshire, and I am a PhD Student, carrying out a research project in the Meldrum group. Previously I had participated in a summer research project and an Integrated Masters project with the Meldrum group as part of my undergraduate studies at the University of Leeds. My Masters project involved using an evolution-inspired genetic algorithm to screen oils for their suitability in microfluidics, more specifically, for efficiency in emulsion PCR. I hope to further explore this work in my PhD Project, with the intention of exploring genetically evolved microfluidic systems to support biological reactions.

Outside of the lab, I like to play guitar, and also practise archery. I enjoy going out with friends to restaurants and movies.

Phillip Lee - PhD Student

Phil

My name is Phillip Lee and I am currently pursuing an industrially sponsored Ph.D. under the supervision of Prof. Fiona Meldrum in collaboration with Unilever. My research is aimed at elucidating the surface structures of a substrate that promote or inhibit crystallisation, using calcium carbonate as a model system. Using clean room techniques applied to silicon, I engineer precisely defined surface topographies; crystallisation is then carried out on these substrates under microfluidic conditions in order to investigate the geometrical effect of specific surface features on the nucleation and growth of crystals.

I received my bachelor’s degree in Nanotechnology from the University of Leeds after which I began my Ph.D. Outside of the lab I enjoy playing/watching football, bike rides, fishing, reading and I am also interested in learning about anything to do with Nature.

Clara Anduix - PhD Student

Clara

My name is Clara Anduix and I am a PhD student at Leeds University. I did a 5 years Chemistry degree at University of Valencia, Spain. Moreover, the last year of my degree I did a crystallisation project in Fiona Meldrum’s group. My research is focused on the crystallisation of inorganic solids in small volumes such as nano-pores, microfluidic devices and Crossed-Cylinders apparatus to see how the crystallisation processes are influenced by confinement. In addition, I’m investigating how changes on the surface chemistry of the materials affect crystallisation. Further work will attend to crystallise proteins in these confinement systems in order to better understand the growth mechanism and crystallisation processes of different proteins.

In my spare time I love travelling and visiting exotic places. I like swimming but also hiking in the mountain. I also enjoy reading and writing, going out with friends and shopping.

Mark Levenstein - PhD Student

Mark

I'm a postgraduate student from the United States. I received my undergraduate degree in Mechanical Engineering at Old Dominion University and subsequently travelled to Leeds as a Fulbright Scholar to complete my Master’s degree with Professor Nik Kapur of the School of Mechanical Engineering and the Meldrum group. Continuing the work I began during my Master’s, now as a PhD student, I seek to utilise microfluidic devices for the processing and screening of biomineralization reactions. More specifically, I use small fluid droplets to compartmentalize these reactions and control morphology and structure by varying flow conditions and fluid properties. I'm also interested in the effect various additives and bio-molecules, added to reactions at different time points, have on crystallization. A significant portion of my research looks at using microfluidics combined with synchrotron X-ray sources for time-resolved crystallization analysis.

Outside of the lab, I love to travel, run and hike, play and listen to music, and enjoy a pint in one of Leeds' many fine pubs!
