Background

Louise Reynard is a Lecturer within the Biosciences Institute at Newcastle University, UK. She graduated from the University of Cambridge with a 1st Class MA Cantab in Natural Sciences, specialising in Genetics. She completed her PhD studies in Developmental Genetics at the MRC National Institute for Medical Research and University College London. Louise joined Newcastle University in 2009 as a post-doctoral researcher, was made a Research Fellow in 2010 and was promoted to Lecturer in 2017. Her research focuses on elucidating the molecular mechanisms through which genetic variation and epigenetic mechanisms impact on gene expression to predispose to musculoskeletal ageing and disease.


Research


Laboratory Techniques

  • targeted chromosome confirmation capture (Capture-C) to identify promoter-transcriptional enhancer interactions
  • ATACseq open chromatin profiling
  • histone ChIPseq and chromatin state learning
  • CRISPR mediated genetic deletion (Cas9) and epigenetic editing (dCas9-DNMT3, dCas9-TET), CRISPRa (dCas9-VPR), CRISPRi (dCas9-KRAB) and CRISPR tagging (dCas9-FLAG)
  • human cell line and primary cell culture
  • transcriptional enhancer reporter assays (luciferase, B -gal)
  • targeted and genome wide DNA methylation profiling (bisulphite pyrosequencing, methylation arrays)
  • transcriptional analysis (RNAseq, qRT-PCR, RNA splicing quantification)
  • EMSAs and in vitro methylation to study effect of DNA methylation on regulatory activity and transcription factor binding
  • western blot, IHC and ICC protein analysis
  • Lentiviral mediated overexpression and siRNA knock downs
  • cloning and bacterial cell culture


Collaborations

Dr Reynard has a wide-ranging network of local, national and international collaborators. Within Newcastle University, Dr Reynard collaborates with Professor David Young to understand the contribution of epigenetics in cartilage development, ageing and disease, and with Professor David Elliott to examine alternative RNA splicing in male infertility and in cartilage development, differentiation, ageing and disease. She also investigates the role of DNA methylation as a mediator, modulator and biomarker of the autoimmune disease rheumatoid arthritis through collaborations with Dr Arthur Pratt, Dr Faye Cooles and Professor John Isaacs, and has recently established a collaboration with Professor Mark Pearce and Dr Andrew Kingston to explore if DNA methylation can act as a biomarker of biological age and predictor of disease risk in the Newcastle 1000 families and 85+ longitudinal cohorts. Dr Reynard is a member of the MRC-ARUK Centre for Integrated Research into Musculoskeletal Ageing and collaborates closely several researchers at the University of Liverpool and University of Manchester. She also works with researchers from Maastrict University and Leiden University in the Netherlands, Harvard University, University of Oklahoma and The Scripps Research Institute in the USA and the University of Sydney, Australia. 


Funding

Dr Reynard’s research is funded by the BBSRC, MRC, Versus Arthritis, the JGW Patterson Foundation, the Dunhill Medical Trust, the Community Foundation, the Newcastle upon Tyne Hospitals Joint Research Executive Scientific Committee and the Lincoln Centre, Sydney, Australia. 


Teaching

Dr Reynard lectures on the undergraduate modules Medical genomics: from DNA to disease, Research in Biochemistry & Genetics, Research in Pharmacological Sciences, and Research in Physiological Sciences, and Masters level modules Chromosome Biology and Cell Cycle Control in Health and Disease, Clinical Epidemiology, Developmental Genetics and Bioinformatics for Biomedical Scientists. Her lectures cover a range of topics from sex-linked genetic disorders and techniques for measuring gene expression to epigenetics and bioinformatic analysis.


Dr Reynard is a member of the MRes Programmes academic team, the largest Masters programme within Newcastle University Faculty of Medical Science, with between 180 and 260 students per year. As part of this role, Dr Reynard is a member of the MRes Curriculum Committee, MRes Board of Studies and MRes Examination Committee. She was the Examination Committee Deputy Chair from 2018 to 2022 and was a member of MRes Moderation and Scaling Committee, MRes Staff-Student Committee, MRes Disciplinary Committee and the MRes Personal Extenuating Circumstances committee during this time.


Dr Reynard supervises undergraduate and MRes laboratory project students, undergraduate vacation project students and PhD students. She was nominated for The Education Awards in 2022 and 2023 in the ‘Research Supervisor of the Year’ category. Louise sits on several PhD progression panels and has acted as an external PhD examiner for the University of Liverpool, University of Manchester and Leiden University, the Netherlands.
