- High-throughput technologies such as next generation sequencing (NGS) can routinely produce massive amounts of data that can be used for tasks such as identifying biological samples with aberrant expression patterns or allow us to describe all variants in a genome. However, such datasets pose new challenges in the way the data have to be analyzed, annotated and interpreted which are not trivial and are daunting to the wet-lab biologist. My interests lie in making the analysis and results of high-throughput data accessible to the non-bioinformatician; via specialised training courses and by developing computational pipelines and workflows.I am currently exploring technologies that facilitate reproducible research and promote an open attitude to scientific research, and endeavour to make my talks, code, and analysis available whenever possible.

Postdoctoral Research Associate, Department of Animal and Plant Sciences
My research is predominantly focused on different aspects of plant-microbe Interactions. Coming from a molecular biology background, I process sequencing data sets and metabolomic data to identify genes, genomic features and metabolic signatures that are involved in the molecular-genetic basis underpinning pathogen virulence and plant immunity. Examples include identifying disease-promoting effectors of Bremia lactucae by de novo assembly of RNAseq from mixed Bremia/host tissue, as well as improving the genome sequence assembly and annotation of Botrytis cinerea. My current project investigates the molecular and epigenetic basis of the onset and long-term (transgenerational) maintenance of plant immune priming.

Lecturer in Bioinformatics, Department of Molecular Biology and Biotechnology
How do cells integrate information to make decisions about what genes should be expressed at a given time and in a given place? How do these processes malfunction to produce disease states? The correct regulation of gene expression is essential for the proper functioning of the cell, and incorrect regulation of genes is central to the mechanisms of many diseases. My interests rest in understanding how the many levels of eukaryotic gene regulation work together to perform these functions, using computational and functional genomics tools.
Examples of recent projects:
- The Polycomb Repressive Complex is targeted to CpG islands by KDM2b
- Reconfiguration of the 3D structure of the genome by a disease causing SNP
- Activation of the WNT pathway by androgen ablation therapy in prostate cancer.
- Association of RNA binding actors with coding and non-coding transcripts
Genome-wide measurement of gene expression at all stages of regulation:
- Transcription (ChIP-seq, ChIP-exo, 4/5/HiC)
- RNA processing (HITS-CLIP/iCLIP)
- RNA stability (RNA-seq, small RNA-seq)
- Translation (Ribosome Profiling)

Lecturer in Genomic Medicine, Department of Neuroscience
We focus on translating the complex patterns of genomic data generated in the lab to enable the development of personalized medicines that can benefit patients suffering from complex diseases. Of computational interest, this involves integrating genomics information of various data types in order to build algorithms that predict clinical outcome and identifying genetic biomarkers through feature selection. Of biomedical interest, we survey the genomic landscape of disease subtypes, as well preclinical models, to better understand how we can stratify patients for different treatments. Both of these aims enable us to work towards the ultimate goal of developing data driven approaches for personalizing medicine.
Examples of recent projects:
- Prognostic impact of genomic instability and immunogenicity in cancer and pulmonary diseases
- Personalizing drug combinations based on genomic features
- Probabilistic modelling of drug response
- Assessment of variant calling metrics for clinical diagnostics (eg. 100K Genome Project)
- Molecular stratification of dementia and Alzheimer’s cases
- Genomic applications in medicine (I co-lead the MSc in Genomic Medicine)
- Statistical inference and machine learning prediction for pharmaco-genomic applications

Senior Lecturer in Genomics and Bioinformatics, Department of Biosciences and Chemistry, Sheffield Hallam University
My interest is using next generation sequencing technologies to understand the genetic basis of disease. Next generation sequencing enables us to detect nearly all the genetic variants in an individual but there are hundreds of thousands of these. The difficulty is in pinpointing which of these contribute to a specific disease. My research explores ways to identify processes that are disrupted in disease from moderate-sized patient groups, assuming that individuals have different variants but that affect a common pathway. I am particularly interested in unravelling the genetic causes of schizophrenia.
