Evie Smith, PhD

Postdoctoral Research Associate

In July 2018 I graduated from an integrated MChem in Chemistry with Biological and Medicinal Chemistry from the University of Sheffield. My Masters' project looked at developing a drug screening assay to find protein interaction inhibitors between amyloid-beta oligomers and cellular prion protein for the potential use in Alzheimer's disease. In October 2018 I began studying for a PhD supervised by Dr. Alison Twelvetrees and Dr Tim Craggs, applying single molecule FRET to understand kinesin activation. I successfully completed my PhD in January 2023 and now work as a postdoc.

I grew up in Cornwall taking part in the traditional pastime of playing in a brass band. I have been lucky enough to play at the Royal Albert Hall twice; once during my time in the National Youth Brass Band of Great Britain.

Emma Turner, PhD

Postdoctoral Research Associate

Emma graduated with a BSc from the University of Sheffield in 2018 and followed this up with an MSc in Translational Neuroscience in 2019. Emma’s MSc project in the Twelvetrees lab led to the award of a PhD scholarship to continue her research career, studying how mutations in kinesin-1 cause neurodegenerative disease. Emma successfully completed he PhD in 2023 and is now continuing her research in her postdoc position in the lab.

J. Michelle Tejeda Rodriguez

PhD student

I did my BA in Clinical Psychology at the Iberoamerican University in The Dominican Republic, which is my home country. During my undergraduate degree, I also undertook two concentrations: Concentration in Research, and Concentration in Neurocognition and Psychophysiology. Afterwards, I worked as a Research Assistant for more than three years at the Iberoamerican University and at the Institute of Tropical Medicine and Global Health in Santo Domingo. In 2020, I received the Chevening Scholarship Award to further my studies and I completed an MSc in Systems Neuroscience at the University of Sheffield. My PhD project aims to assess the tubulin dynamics supporting neuronal longevity and how this goes wrong in neurodegenerative disorders.

Haydn Tortoishell

PhD student

I graduated with a BSc in Biosciences from Durham University in 2019. I then continued my studies at the University of Manchester, where I completed a research Masters degree in Neuroscience. During my project I investigated mechanistic links between kinesin dysfunction, subsequent microtubule damage, and axonopathy. Following on from this I tried my hand in Industry, working at AstraZeneca for a year and a half. Deciding that academic research is the path I am most passionate about, I have now started my PhD journey at SITraN. During my project my initial aim is to investigate cross-talk between axon maintenance and DNA damage repair, and possible links with neurodegeneration.

Ali Twelvetrees

I currently hold a Sir Henry Dale Fellowship to study the molecular mechanisms of slow axonal transport. In 2017 I moved to Sheffield University and the Sheffield Institute for Translational Neuroscience as a Vice Chancellor’s Fellow, where I have established my independent research group. Prior to this, as a post-doc I worked on the coordination of microtubule-dependent motors during axonal transport with Prof Erika Holzbaur at the University of Pennsylvania and Prof Giampietro Schiavo at the UCL Institute of Neurology. I obtained my PhD under the supervision of Prof Josef Kittler in the department of Neuroscience, Physiology and Pharmacology at University College London (UCL) whilst studying the molecular mechanisms of gamma-aminobutyric acid type A receptor (GABA-A receptor) transport by kinesin in neurons.

I knit, garden and walk to unwind when I can. I recently started running and I’m rubbish at it, but Sheffield scenery makes up for it!

2023

Ashleigh Davey, PhD

Ashleigh graduated with an MBiolSci integrated Masters from the University of Sheffield in 2019, which involved an extended laboratory project in the Twelvetrees lab constructing microfluidic devices to study axonal transport. Ashleigh was awarded a PhD scholarship to continue her research career, investigating the mechanisms behind the translocation of ribosomes in neurons in collaboration with the Thomson Lab in the School of Biological Sciences. During her postgraduate studies Ashleigh explored the world of science writing and communication, contributing to the PreLights preprint highlighting project. She now works as a science writer for Frontline Genomics.

2023 was a busy year for the lab, as both current postdocs Emma and Evelyn also successfully defended their theses!
