Overview
My interests lie in applied, innovative research. I am currently working with Volac International Ltd. to develop their whole genome bioinformatic analysis capability for animal nutirition. This project is a Knowledge Transfer Partnership joint funded by Volac and Innovate UK.
Previously, I generated a large collection of Dictyostelium variants as a community resource (funded by the Wellcome Trust). The social amoeba, Dictyostelium, is an amenable and economical model especially for studying process involved in human health and disease. I have previously worked with the model plant, Arabidopsis, and also developed techniques for introducing variation into individual genes for directed evolution.
I am part of the Microbiomes, Microbes and Informatics (MMI) group.
I am a Biosciences' Research Staff Group representative and part of the Cardiff sciSCREEN organising team.

Research
I specialise in generating and utilising large collections of strains to discover the mechanisms behind biological processes, both in the 'wet-lab' and through informatics. I also develop tools that facilitate others accessing specialist technologies.
As part of a project funded by the Wellcome Trust, I have generated a large collection of Dictyostelium variants as a community resource. The social amoeba, Dictyostelium, is an amenable and economical model especially for studying process involved in human health and disease.
Previously, I have generated and screened a large collection of Arabidopsis variants. One of the variants was further characterised and shown to be a key component in making plants resilient to harsh conditions such as drought; this knowledge is now being used to study how crop yields will not be compromised in an unreliable climate.
I have also developed techniques for directed evolution including TriNEx which is a method for generating large libraries of single amino acid substitutions for single proteins which can be screened in vivo.

Biography
I obtained my B.Sc. degree in Biological Sciences (Biochemistry) from the University of Leicester and subsequently a Ph.D. in Plant Molecular Genetics. I spent 2 years as an International Scholar at the Department of Plant Sciences in UCDavis.
I joined Cardiff University in 2006 to develop direct evolution techniques within Dr Dafydd Jones' group. I have since worked for the Marie Curie Palliative Care Research Centre (MCPCRC) based within the Wales Clinical Trials Unit (WCTU), and the Wales Gene Park as a Public Engagement Officer. In 2014 I joined the Harwood group in the Cardiff School of Biosciences to generate a genome wide mutant resource for Dictyostelium functional genomics (REMI-seq).
Presently, I am developing whole genome bioinformatic analysis capability for animal nutrition. This is a partnership between an international dairy business (Volac Int. Ltd.) and Cardiff University's Microbiomes, Microbes and Informatics (MMI) group.

Engagement
You can read about my current research project in my latest article for The Conversation: ‘We’re holding an amoeba Olympics to uncover the mechanisms behind human diseases’.
I am a member of the organising team for the popular engagement series, Cardiff sciSCREEN. Cardiff sciSCREEN is a cross-disciplinary programme that uses local academic expertise to discuss themes and issues raised by contemporary cinema in an entertaining and informative way. We have run more than 50 events to date exploring topics such as cloning, memory, gene environment interactions, natural selection, engaging with the outdoors and mental health. To find out more visit our website or Twitter feed @sciscreen. If you are interested in engaging the public with your research via film please get in touch.
You can find out more in our recent article in the first issue of the new engagement journal ‘Research for All’: Cardiff sciSCREEN: A model for using film screenings to engage publics in university research.
I have contributed to the SOCSI M.Sc. module ‘Public Engagement with Science and Technology’, and taught the BBSRC DTP PhD students about ‘Social Media: Understanding and exploiting its potential for research’.
Brain Games: fun and interactive activities with the Porthcawl Cub Scout group and St. Paul’s Primary School (#MRCFestival).
While working for the Wales Gene Park I organised the biennial Genetics Roadshow, which visited 19 of the 22 Welsh counties. More than 4,000 students from 73 schools and colleges heard about the latest advances in genetics from experts from universities, the NHS and police forces. The students also gained an insight into genetics-related courses and careers.
